Description

An embodiment of the present invention relates to a vehicle slide rail device.

Conventionally, a slide rail device for a vehicle including a lower rail fixed to the floor of a vehicle and an upper rail fixed to a seat is known. The upper rail is attached to the lower rail and can move with the seat along the lower rail.

The lower rail is provided with an opening extending in the moving direction of the upper rail. The upper rail is arranged inside and outside the lower rail through the opening. The vehicle slide rail device comprises, for example, a pair of covers capable of covering the opening.

The pair of covers attach to the lower rail and extend along the opening. Each pair of covers has a soft portion. When the two soft parts come into contact with each other or are in close proximity to each other on the opening, the soft parts close the opening. The upper rail moves along the opening while elastically deforming the soft portion so as to widen the gap between the two soft portions (Patent Document 1).

Japanese Unexamined Patent Publication No. 2007-609854

However, in the conventional configuration, a gap may occur between the pair of covers. In this case, foreign matter may enter the inside of the lower rail through the opening through the gap between the pair of covers.

Therefore, the present invention has been made in view of the above, and provides a slide rail device for a vehicle capable of suppressing foreign matter from entering the inside of the rail.

The vehicle slide rail device according to the embodiment of the present invention has, for example, a first wall extending in a first direction, extending in the first direction, and orthogonal to the first direction from the first wall. A rail that has a second wall that is spaced apart in a second direction and is provided with an opening extending in the first direction between the first wall and the second wall and is mounted on the floor. And a slider that is at least partially located inside the opening and movably attached to the rail in the first direction, and attached to at least one of the rail and the floor outside the rail. A cover comprising a mounting portion, a covering portion movably connected to the mounting portion between a closed position covering the entire area of the opening in the second direction and an open position separated from the opening, and the said. A holding portion for holding the covering portion in the closed position is provided. Therefore, as an example, one covering portion covers the entire area of the opening in the second direction, and the covering portion is held at the closed position by the holding portion, so that foreign matter is suppressed from entering the inside of the rail from the opening. Rail.

In the vehicle slide rail device, as an example, the mounting portion is attached to at least one of the rail and the floor at a position separated from the second wall in a third direction opposite to the second direction. Attached, the holding portion is provided on the covering portion of the rail and the floor at a position separated from the first wall in the second direction when the covering portion is located at the closed position. It is held in at least one. Therefore, as an example, the portion where the mounting portion is mounted and the portion where the holding portion is held are separated from each other and are less likely to interfere with each other, so that the degree of freedom in designing the slide rail device is improved.

In the vehicle slide rail device, as an example, the rail is orthogonal to the first direction and is orthogonal to the second direction from the end of the second wall in the second direction or the end in the third direction. It has a third wall extending in a fourth direction intersecting the direction of the above, and the holding portion is held by the third wall when the covering portion is located at the closed position. Therefore, as an example, it is not necessary to provide a structure for holding the holding portion on the second wall, and the width of the second wall in the second direction can be shortened.

In the vehicle slide rail device, as an example, the holding portion includes a first portion provided on the covering portion and a second portion provided on at least one of the rail and the floor. The cover portion is held in the closed position by having one of the first portion and the second portion caught on the other with elastic deformation. Therefore, as an example, it is possible to simplify the structure of the holding portion.

In the vehicle slide rail device, as an example, the slider has a release portion that releases the holding portion of the cover portion by the holding portion as the slider moves. Therefore, as an example, since the covering portion can move from the closed position to the open position with the movement of the slider, the movement of the slider and the covering portion becomes smooth.

In the vehicle slide rail device, as an example, the slider has a first pressing portion that pushes the covering portion separated from the opening to the closed position. Therefore, as an example, even if the holding portion is provided, the covering portion that can move between the open position and the closed position can surely move to the closed position and cover the opening.

In the vehicle slide rail device, as an example, the slider is such that one of the first portion and the second portion is caught on the other with elastic deformation as the slider moves. The cover portion separated from the opening is pushed to the closed position. Therefore, as an example, the covering portion that is accompanied by elastic deformation of the first portion or the second portion when moving from the open position to the closed position can be reliably moved to the closed position.

In the vehicle slide rail device, as an example, the second portion has a first state in which the cover portion can be caught in the first portion when the cover portion is located at the closed position, and the cover portion. Is elastically deformable between a second state, which is more distant from the first portion than the first state, when is located in the closed position, and the slider is moved with the movement of the slider. The second portion of the first state is described so that the second portion is in the second state at the position where the first pressing portion in the first direction pushes the covering portion. It has a second pressing portion that elastically deforms to the second state. Therefore, as an example, it is not necessary for the first portion to significantly elastically deform the second portion, and the second portion can suppress the generation of noise due to the elastic deformation.

(First Embodiment)
Hereinafter, the first embodiment will be described with reference to FIGS. 1 to 6. In this specification, the constituent elements according to the embodiment and the description of the elements may be described in a plurality of expressions. The components and their description are examples and are not limited by the representations herein. The components may also be identified by names different from those herein. The components may also be described by expressions different from those herein.

FIG. 1 is a side view schematically showing the seat device 10 of the first embodiment. The seat device 10 is mounted on the floor 2 of a vehicle 1 such as a four-wheeled vehicle, and has a slide rail device 11 and a seat 12. The seat 12 has a seat cushion 12a and a seat back 12b rotatably attached to the seat cushion 12a.

As shown in each drawing, the X-axis, Y-axis and Z-axis are defined herein for convenience. The X-axis, Y-axis, and Z-axis are orthogonal to each other. The X-axis is provided along the left-right direction of the vehicle 1. The Y-axis is provided along the front-rear direction of the vehicle 1. The Z-axis is provided along the vertical direction of the vehicle 1.

Further, in the present specification, the X direction, the Y direction and the Z direction are defined. The X direction is a direction along the X axis and includes the + X direction (left direction) indicated by the arrow on the X axis and the −X direction (right direction) which is the opposite direction of the arrow on the X axis. The Y direction is a direction along the Y axis and includes a + Y direction (forward direction) indicated by an arrow on the Y axis and an −Y direction (rear direction) which is the opposite direction of the arrow on the Y axis. The Z direction is a direction along the Z axis, and includes a + Z direction (upward direction) indicated by an arrow on the Z axis and a −Z direction (downward direction) opposite to the arrow on the Z axis.

FIG. 2 is a cross-sectional view showing a part of the slide rail device 11 of the first embodiment. The slide rail device 11 shown in FIG. 2 has two rails 21, two sliders 22, and a drive device 23. 1 and 2 show one rail 21 and one slider 22.

Each of the two rails 21 has a lower rail 25. The lower rail 25 is attached to the floor 2 of the vehicle 1 so as to extend in the Y direction. The Y direction may also be referred to as the first direction. The + Y direction or the −Y direction may be referred to as the first direction.

The floor 2 has a floor surface 2a facing in the substantially + Z direction. The floor surface 2a may have a portion facing in another direction. Two grooves 2b are provided on the floor surface 2a. FIG. 2 shows one groove 2b. The groove 2b is recessed from the floor surface 2a in the substantially −Z direction and extends in the Y direction.

The groove 2b has, for example, a substantially rectangular cross section in a cross section orthogonal to the Y direction as shown in FIG. In this case, the floor 2 has a bottom surface 2ba and two inner side surfaces 2bb forming one groove 2b.

The bottom surface 2ba is separated from the floor surface 2a in the substantially −Z direction and faces in the substantially + Z direction. The two inner side surfaces 2bb extend in the substantially Z direction between both ends of the bottom surface 2ba in the X direction and the floor surface 2a. The two inner side surfaces 2bb are separated from each other in the X direction and face each other in the substantially X direction.

The bottom surface 2ba is formed by, for example, the floor panel 2c. The floor surface 2a and the inner side surface 2bb are formed of, for example, a carpet 2d. The floor 2 is not limited to this example. For example, the floor panel 2c may form the bottom surface 2ba and the inner side surface 2bb.

The two grooves 2b are arranged apart from each other in the X direction. The lower rail 25 of the corresponding rail 21 is accommodated in each of the two grooves 2b. As a result, the two lower rails 25 are arranged apart from each other in the X direction. The lower rail 25 is attached to, for example, the bottom surface 2ba of the groove 2b by a bolt. The lower rail 25 may be attached to the floor 2 by other means.

The slider 22 has an upper rail 26 and a guide member 27, respectively. The upper rail 26 extends in the Y direction and is slidably movable in the Y direction, and is attached to the lower rail 25.

The Y direction is the longitudinal direction of the lower rail 25 and the longitudinal direction of the upper rail 26. Further, the X direction is the width direction of the lower rail 25 and the width direction of the upper rail 26.

A pair of left and right sliders 22 support one seat 12. The pair of sliders 22 are connected to each other by, for example, a sheet 12. Therefore, the pair of sliders 22 slide and move integrally in the Y direction together with the seat 12. In addition, another member may connect a pair of sliders 22.

In the following description, one of the two lower rails 25 arranged in the X direction and one of the pair of left and right sliders 22 arranged in the X direction will be typically described. The other of the two lower rails 25 arranged in the X direction and the other of the pair of left and right sliders 22 arranged in the X direction are formed mirror-symmetrically in the X direction with respect to the lower rail 25 and the slider 22 described, for example. ..

One of the two lower rails 25 arranged in the X direction, which is described, is separated from the other in the −X direction. Further, one of the pair of sliders 22 arranged in the X direction, which is described, is separated from the other in the −X direction. Therefore, in the following description, the + X direction may be referred to as the inside in the width direction, and the −X direction may be referred to as the outside in the width direction. That is, the inside in the width direction is the direction toward the other lower rail 25 and the slider 22 in the X direction. The outer side in the width direction is the direction opposite to the direction toward the lower rail 25 and the slider 22 in the other X direction.

FIG. 3 is a cross-sectional view showing the lower rail 25 and the upper rail 26 of the first embodiment. As shown in FIG. 3, the lower rail 25 is made of, for example, a single bent sheet metal and has a substantially C-shaped cross section. The lower rail 25 is not limited to this example.

The lower rail 25 has a bottom wall 31, two outer walls 32, 33, two upper walls 34, 35, and two inner walls 36, 37. The upper wall 34 may also be referred to as a first wall or wall. The upper wall 35 may also be referred to as a second wall. The upper wall 34 may be referred to as a second wall, and the upper wall 35 may be referred to as a first wall.

The bottom wall 31 is a substantially rectangular plate-shaped wall that extends substantially in the XY plane and extends in the Y direction. The bottom wall 31 extends in the substantially X direction in a cross section orthogonal to the Y direction as shown in FIGS. 2 and 3. The bottom wall 31 may have, for example, uneven and bent portions.

The outer wall 32 is connected to the end of the bottom wall 31 on the outer side in the width direction (−X direction) and extends in the substantially Z direction. As shown in FIG. 3, a diagonally extending corner portion may be provided between the bottom wall 31 and the outer wall 32. The outer wall 32 has an outer surface 32a facing the outside of the lower rail 25. The outer surface 32a faces in the substantially -X direction. The outer surface 32a faces the inner side surface 2bb on the outer side in the width direction of the floor 2.

The outer wall 33 is connected to the end of the bottom wall 31 on the inner side in the width direction (+ X direction) and extends in the substantially Z direction. As shown in FIG. 3, a diagonally extending corner portion may be provided between the bottom wall 31 and the outer wall 33. The outer wall 33 has an outer surface 33a facing the outside of the lower rail 25. The outer surface 33a faces in the substantially + X direction. The outer surface 33a faces the inner side surface 2bb on the inner side in the width direction of the floor 2.

The upper wall 34 is a substantially rectangular plate-shaped wall that extends on the XY plane and extends in the Y direction. The upper wall 34 is connected to the end of the outer wall 32 in the + Z direction and extends from the outer wall 32 in the substantially + X direction. The upper wall 34 has an outer surface 34a facing the outside of the lower rail 25. The outer surface 34a is formed substantially flat and faces in the substantially + Z direction.

The upper wall 35 is a substantially rectangular plate-shaped wall that extends on the XY plane and extends in the Y direction. The upper wall 35 is connected to the end of the outer wall 33 in the + Z direction and extends from the outer wall 32 in the substantially −X direction. That is, the upper wall 34 and the upper wall 35 extend so as to approach each other. The upper wall 35 has an outer surface 35a facing the outside of the lower rail 25. The outer surface 35a is formed substantially flat and faces in the substantially + Z direction.

The upper wall 35 is separated from the upper wall 34 in the radial direction (+ X direction). The radial inside (+ X direction) is orthogonal to the Y direction and may also be referred to as a second direction. In the Z direction, the upper wall 34 and the upper wall 35 are provided at substantially the same position. Therefore, the outer surface 34a of the upper wall 34 and the outer surface 35a of the upper wall 35 are arranged on substantially the same plane. As shown in FIG. 2, the outer surface 34a of the upper wall 34 and the outer surface 35a of the upper wall 35 are separated from the floor surface 2a of the floor 2 in the −Z direction. The outer surfaces 34a and 35a may be arranged on substantially the same plane as the floor surface 2a.

As shown in FIG. 3, the inner wall 36 is a substantially rectangular plate-shaped wall that extends on the YZ plane and extends in the Y direction. The inner wall 36 extends in the substantially −Z direction from the + X direction end of the upper wall 34. The end of the inner wall 36 in the −Z direction is separated from the bottom wall 31.

The inner wall 37 is a substantially rectangular plate-shaped wall that extends on the YZ plane and extends in the Y direction. The inner wall 37 extends in the −Z direction from the −X direction end of the upper wall 35. The end of the inner wall 37 in the −Z direction is separated from the bottom wall 31.

As described above, the inner wall 37 extends in the −Z direction from the widthwise outer (−X direction) end of the upper wall 35. Further, the outer wall 33 extends in the −Z direction from the inner end (+ X direction) in the width direction of the upper wall 35. The outer side in the width direction (-X direction) is the opposite direction to the + X direction, and may also be referred to as a third direction. The −Z direction is orthogonal to the Y direction and intersects the + X direction, and may also be referred to as a fourth direction. The outer wall 33 and the inner wall 37 may also be referred to as a third wall.

The inner walls 36, 37 are located between the two outer walls 32, 33. The inner walls 36 and 37 are separated from the outer walls 32 and 33 in the X direction. Further, the inner wall 37 is separated from the inner wall 36 in the + X direction.

The lower rail 25 is provided with an internal space 38 and an opening 39. The opening 39 may also be referred to as a groove. The internal space 38 is provided inside the lower rail 25. For example, the internal space 38 is surrounded by the bottom wall 31, the outer walls 32, 33, and the upper walls 34, 35, and extends in the Y direction.

The opening 39 is formed (defined) between the two inner walls 36, 37 by, for example, two inner walls 36, 37. Therefore, the opening 39 is provided between the upper wall 34 and the upper wall 35, and extends in the Y direction. The opening 39 communicates the internal space 38 with the outside of the lower rail 25.

The upper rail 26 is made of, for example, a single sheet metal that has been bent. The upper rail 26 is not limited to this example. The upper rail 26 has an upper wall 41, two side walls 42, and two curved walls 43.

The upper wall 41 is a substantially rectangular plate-shaped wall that extends on the XY plane and extends in the Y direction. The upper wall 41 extends in the X direction in a cross section orthogonal to the Y direction. The upper wall 41 is located outside the lower rail 25.

The two side walls 42 extend in the substantially −Z direction from both ends of the upper wall 41 in the X direction. The two side walls 42 extend substantially parallel and are separated from each other. The side wall 42 extends through the opening 39 of the lower rail 25. Therefore, the upper rail 26 is located at least partially inside the opening 39.

In the cross section orthogonal to the Y direction, the two curved walls 43 are located in the internal space 38 of the lower rail 25. The widthwise outer curved wall 43 extends from the widthwise outer side wall 42 toward the space between the outer wall 32 and the inner wall 36. The curved wall 43 on the inner side in the width direction extends from the side wall 42 on the inner side in the width direction toward the space between the outer wall 33 and the inner wall 37.

The curved wall 43 is formed in a barb shape. The shape of the curved wall 43 is not limited to this example. For example, when an impact acts on the vehicle 1, the seat 12 and the upper rail 26 may move in the substantially + Z direction. In this case, the curved wall 43 is received by the lower rail 25. As a result, the upper rail 26 is prevented from being arbitrarily detached from the lower rail 25.

A plurality of rollers 45, 46 are attached to the side wall 42. The plurality of rollers 45 can roll in the Y direction on the bottom wall 31 of the lower rail 25. As a result, the slider 22 can move smoothly in the Y direction. The plurality of rollers 46 abut on the inner wall 36 or the inner wall 37 of the lower rail 25, and restrict the upper rail 26 from moving in the Z direction with respect to the lower rail 25.

For example, in the Y direction, the curved wall 43 is not provided at the portion of the upper rail 26 to which the rollers 45 and 46 are attached. The upper rail 26 is not limited to this example, and for example, the curved wall 43 may be provided with a hole or a notch through which the rollers 45 and 46 pass.

FIG. 4 is a perspective view showing the slider 22 of the first embodiment in an exploded manner. The guide member 27 shown in FIG. 4 is a member different from the upper rail 26 made of, for example, a synthetic resin. The guide member 27 may be made of another material. The guide member 27 has a mounting wall 51, a guide side wall 52, and two guide end walls 53.

The mounting wall 51 is a substantially rectangular plate-shaped wall that extends on the XY plane and extends in the Y direction. The mounting wall 51 is arranged on the upper wall 41 of the upper rail 26. The mounting wall 51 is attached to the upper wall 41, for example, by a bolt. The guide member 27 may be attached to the upper rail 26 at another position.

The guide side wall 52 projects from the mounting wall 51 so as to be away from the upper rail 26. For example, the guide side wall 52 projects outward in the width direction from the end 51a on the outer side in the width direction of the mounting wall 51. The guide side wall 52 projects outward in the width direction from the side wall 42 on the outer side in the width direction of the upper rail 26. The guide side wall 52 may protrude from the mounting wall 51 in another direction such as the + Z direction.

The guide side wall 52 has, for example, a first support edge 52a and two second support edges 52b. The first support edge 52a and the second support edge 52b are widthwise outer edges of the guide side wall 52.

The first support edge 52a extends substantially linearly in the Y direction. The two second support edges 52b extend between both ends of the first support edge 52a in the Y direction and the two guide end walls 53. The distance between the second support edge 52b and the mounting wall 51 in the X direction becomes shorter as the distance from the first support edge 52a increases.

The two guide end walls 53 project from both ends of the mounting wall 51 in the Y direction. At least a portion of the guide end wall 53 is located between the two side walls 42 of the upper rail 26 in the X direction.

Each of the two guide end walls 53 has a support surface 53a. The distance between the support surface 53a and the bottom wall 31 of the lower rail 25 in the Z direction becomes shorter as the distance from the mounting wall 51 increases. In other words, the support surface 53a extends diagonally downward from the mounting wall 51.

The drive device 23 shown in FIG. 2 moves the slider 22 in the Y direction with respect to the lower rail 25. The drive device 23 includes a screw rod 61, a motor 62, and a conversion mechanism 63. FIG. 2 schematically shows the motor 62.

The screw rod 61 is fixed to the lower rail 25, for example, and extends in the Y direction. The screw rod 61 is located in the internal space 38 or the opening 39, and is located inside the upper rail 26. A male screw is formed on the outer surface of the screw rod 61.

The motor 62 is attached to the slider 22 via various members, for example, at a position separated inward in the width direction from the slider 22. The motor 62 is, for example, a servomotor, and is driven according to the control of the ECU (Electronic Control Unit) of the vehicle 1. In this embodiment, one motor 62 is attached to one slider 22. However, one common motor 62 may be provided for the pair of left and right sliders 22.

The conversion mechanism 63 is attached to the slider 22. The conversion mechanism 63 includes, for example, a nut attached to the screw rod 61 and various components such as shafts, gears, worms, and worm wheels that transmit rotation between the nut and the motor 62.

When the nut of the conversion mechanism 63 is rotationally driven by the motor 62, the slider 22 moves relative to the lower rail 25 in the Y direction. In this way, the conversion mechanism 63 converts the rotation generated by the motor 62 into the linear motion of the slider 22.

As described above, the seat device 10 of the present embodiment is a power seat driven by a motor 62. However, the seat device 10 may be able to manually move the slider 22 in the Y direction by the user.

Each of the two rails 21 further comprises a fixture 70. The fixture 70 is made of, for example, a single bent sheet metal. The fixture 70 may be made of another material.

The fixture 70 is located outside the lower rail 25 and is attached to the lower rail 25. In the present embodiment, a plurality of attachments 70 are arranged in the Y direction with an interval, and are attached to the lower rail 25. In addition, one fixture 70 may be attached to the lower rail 25. The fixture 70 has a lower wall 71, a standing wall 72, and a holding claw 73.

The lower wall 71 is attached to the bottom wall 31 of the lower rail 25, for example, by welding or by bolts. The lower wall 71 is located between the bottom wall 31 and the bottom surface 2ba of the groove 2b of the floor 2. The lower wall 71 extends outward in the width direction from the bottom wall 31 and projects outward in the width direction from the outer wall 32 of the lower rail 25.

The vertical wall 72 extends in the substantially + Z direction from the end of the lower wall 71 on the outer side in the width direction. The vertical wall 72 extends along the outer wall 32. The vertical wall 72 is located between the outer surface 32a of the outer wall 32 and the inner side surface 2bb on the outer side in the width direction of the groove 2b of the floor 2. However, the fixture 70 of the present embodiment is not provided between the outer surface 33a of the outer wall 33 and the inner side surface 2bb on the inner side of the groove 2b of the floor 2 in the width direction. A part of the fixture 70 may be provided between the outer surface 33a and the inner side surface 2bb on the inner side in the width direction.

The vertical wall 72 may be in contact with the outer wall 32 or may be separated from the outer wall 32. The vertical wall 72 can be elastically deformed so as to be separated from the outer wall 32 with the connecting portion of the lower wall 71 and the vertical wall 72 or its vicinity as a fulcrum.

The holding claw 73 is provided at the end of the standing wall 72 in the + Z direction. The holding claw 73 is bent so as to be recessed outward in the width direction. In other words, the holding claw 73 is bent so as to be recessed in a direction away from the outer wall 32. Therefore, a holding space 75 is provided between the holding claw 73 and the outer wall 32. The end of the holding claw 73 in the + Z direction is substantially at the same position as the outer surface 34a of the upper wall 34 in the Z direction, or is separated from the outer surface 34a in the −Z direction.

The slide rail device 11 further comprises two covers 80 corresponding to the two rails 21. FIG. 2 shows one cover 80. The slide rail device 11 may have three or more covers 80.

The cover 80 is arranged apart from the bottom surface 2ba of the groove 2b of the floor 2 in the + Z direction (upward direction). The cover 80 can cover the corresponding rail 21 and the groove 2b in which the rail 21 is housed. Each cover 80 has a mounting portion 81, a plurality of covering portions 82, a plurality of flexible portions 83, and a plurality of holding portions 84. The holding portion 84 may also be referred to as a first portion.

The mounting portion 81, the covering portion 82, and the holding portion 84 are made of, for example, a synthetic resin such as polyacetal (POM).

The engaging portion 92b is provided on the protruding portion 92a at a position separated from the base portion 91 in the −Z direction.

In the X direction, the width of the engaging portion 92b is larger than the width of the protruding portion 92a. For example, the engaging portion 92b has a portion protruding outward in the width direction from the protruding portion 92a. That is, the protrusion 92 is thin at the protrusion 92a near the base 91 and thick at the engagement portion 92b away from the base 91.

As shown in FIG. 2, the protrusion 92 is arranged between the outer surface 32a of the outer wall 32 of the lower rail 25 and the holding claw 73 of the fixture 70. For example, the protrusion 92 elastically deforms the standing wall 72 of the fixture 70 and is inserted into the gap between the outer surface 32a and the holding claw 73. The protrusion 92 may be elastically deformed and inserted into the gap between the outer surface 32a and the holding claw 73.

The mounting portion 81 is mounted on the rail 21 by accommodating the engaging portion 92b of the protrusion 92 in the holding space 75. For example, the holding claw 73 abuts on the engaging portion 92b and limits the engaging portion 92b from coming off the holding space 75 in the + Z direction. The mounting portion 81 may be mounted on the rail 21 by, for example, an adhesive, a screw, or other means.

In this embodiment, the mounting portion 81 is mounted on the rail 21, but the mounting portion 81 is not limited to this example. For example, the mounting portion 81 may be mounted on the floor 2 by an adhesive, screws, or other means.

Further, for example, even if the fixture 70 is omitted from the rail 21, the protrusion 92 is sandwiched (held) between the outer surface 32a of the outer wall 32 of the lower rail 25 and the inner side surface 2bb of the groove 2b on the outer side in the width direction of the floor 2. good. In this case, the mounting portion 81 is mounted on the floor 2 and the rail 21.

Each of the plurality of covering portions 82 is movably connected to the mounting portion 81 between the closed position Pc and the open position Po by the corresponding flexible portion 83.

The covering portion 82 of the closed position Pc extends on the XY plane and extends in the X direction. At the covering portion 82 of the closed position Pc, the length in the Y direction is shorter than the length in the X direction. The dimension of the covering portion 82 is not limited to this, and the length in the Y direction may be the same as or longer than the length in the X direction. In the Y direction, the covering portion 82 is shorter than the mounting portion 81.

At the closed position Pc, the covering portion 82 extends inward in the width direction from the flexible portion 83 and covers the opening 39 of the lower rail 25 at least partially. In the present embodiment, as described below, the covering portion 82 of the closed position Pc covers the entire area of the opening 39 in the X direction and also covers a part of the opening 39 in the Y direction. The covering portion 82 of the closed position Pc covers, for example, the screw rod 61 located inside the lower rail 25.

In the X direction, the length of the covering portion 82 of the closed position Pc is longer than the width of the opening 39. The covering portion 82 of the closing position Pc covers the entire area of the opening 39 in the X direction. In other words, the covering portion 82 of the closed position Pc covers from the end in the −X direction to the end in the + X direction of the opening 39. Further, in the present embodiment, the covering portion 82 of the closed position Pc covers at least a part of the upper wall 34 in the X direction and the entire area of the upper wall 35 in the X direction. The covering portion 82 of the closed position Pc may expose the upper wall 35 as long as it covers the entire area of the opening 39 in the X direction.

In the Y direction, the length of the covering portion 82 is shorter than any of the lengths of the opening 39, the upper wall 34, and the upper wall 35. Therefore, in the Y direction, one covering portion 82 covers a part of the opening 39, a part of the upper wall 34, and a part of the upper wall 35.

On the other hand, at the open position Po, the covering portion 82 is separated from the opening 39 of the lower rail 25. The covering portion 82 of the open position Po extends away from the opening 39 as it goes away from the mounting portion 81 and the flexible portion 83. In other words, the covering portion 82 extends diagonally upward from the flexible portion 83. Therefore, the covering portion 82 of the open position Po is exposed without covering the opening 39.

The plurality of covering portions 82 are arranged side by side in the Y direction. As a result, the plurality of covering portions 82 located at the closed position Pc cover the opening 39. A gap may be provided between two adjacent covering portions 82. The gap is shorter than the length (width) of the covering portion 82 in the Y direction. The width of the gap is set so that, for example, human fingers, pens, lighters, and high heels can be prevented from passing through. The gap is not limited to this example. Further, the two adjacent covering portions 82 may be in close contact with each other without a gap.

At the closed position Pc, the first surface 82a faces in the substantially + Z direction. As shown in FIG. 2, the first surface 82a of the closed position Pc is located substantially on the same plane as the upper surface 91b of the base 91 of the mounting portion 81 and the floor surface 2a of the floor 2.

At the closed position Pc, the second surface 82b faces in the substantially −Z direction. As shown in FIG. 2, the second surface 82b of the closed position Pc is supported by the outer surface 34a of the upper wall 34, the outer surface 35a of the upper wall 35, and the concave surface 2e. Therefore, the cover 80 of the present embodiment can cover the entire area of the groove 2b in the X direction.

The covering portion 82 of the closed position Pc and the inner side surface 2bb on the inner side in the width direction of the groove 2b may be aligned in the X direction through a gap. Further, the base portion 91 of the mounting portion 81 and the inner side surface 2bb on the outer side in the width direction of the groove 2b may be aligned in the X direction through a gap. In this case, the distance between the cover 80 and the inner surface 2bb is set so that, for example, human fingers, pens, lighters, and high heels can be prevented from passing through.

As shown in FIG. 6, the end face 82c is provided at one end in the direction in which the covering 82 extends. When the covering portion 82 is located at the closed position Pc, the end surface 82c is located at the outer end in the width direction of the covering portion 82 and faces outward in the width direction. The end face 82c at the closed position Pc faces the end face 91c of the base 91 via an interval.

The flexible portion 83 connects the mounting portion 81 and the covering portion 82. In the present embodiment, the flexible portion 83 connects the end surface 91c of the base portion 91 of the mounting portion 81 and the end surface 82c of the covering portion 82. The flexible portion 83 may connect the mounting portion 81 and other portions of the covering portion 82 to each other.

The accommodating groove 91d and the engaging groove 91e are provided in the base portion 91 of the mounting portion 81. The accommodating groove 91d may also be referred to as a first recess. The engaging groove 91e may also be referred to as a second recess. The accommodating groove 91d is a substantially rectangular groove that is recessed outward in the width direction from the end surface 91c of the base portion 91. The radial outside may also be referred to as a third direction. The engaging groove 91e is a substantially rectangular groove that is recessed from the inner surface of the accommodating groove 91d in, for example, the −Z direction at a position separated from the end surface 91c. The −Z direction is a direction that intersects the outside in the width direction, and may also be referred to as a fourth direction. The accommodating groove 91d and the engaging groove 91e extend in the Y direction.

An accommodating groove 82d and an engaging groove 82e are provided on the end surface 82c of the covering portion 82. The accommodating groove 82d may also be referred to as a first recess. The engaging groove 82e may also be referred to as a second recess. The accommodating groove 82d is a substantially rectangular groove that is recessed inward in the width direction from the end surface 82c of the covering portion 82. The radial medial side may also be referred to as a third direction. The engaging groove 82e is a substantially rectangular groove that is recessed from the inner surface of the accommodating groove 82d in, for example, the −Z direction at a position separated from the end surface 82c. The −Z direction is a direction that intersects the inside of the width direction, and may also be referred to as a fourth direction.

The flexible portion 83 has a first end portion 83a, a second end portion 83b, and an intermediate portion 83c. The first end portion 83a is a part of the flexible portion 83 and is accommodated in the accommodating groove 91d and the engaging groove 91e of the base 91. The second end portion 83b is a part of the flexible portion 83 and is accommodated in the accommodating groove 82d and the engaging groove 82e of the covering portion 82. The intermediate portion 83c is provided between the first end portion 83a and the second end portion 83b.

The first end portion 83a is fixed to the inner surface of the accommodating groove 91d and the inner surface of the engaging groove 91e. Further, since the first end portion 83a has entered the engaging groove 91e, the inner surface of the engaging groove 91e restricts the flexible portion 83 from coming out of the accommodating groove 91d and the engaging groove 91e.

The second end portion 83b is fixed to the inner surface of the accommodating groove 82d and the inner surface of the engaging groove 82e. Further, since the second end portion 83b has entered the engaging groove 82e, the inner surface of the engaging groove 82e restricts the flexible portion 83 from coming out of the accommodating groove 82d and the engaging groove 82e.

The intermediate portion 83c covers a part of the upper wall 34 in the X direction. When the covering portion 82 is located at the closed position Pc, the intermediate portion 83c is supported by the outer surface 34a of the upper wall 34. When the covering portion 82 is located at the closed position Pc, the intermediate portion 83c may be separated from the upper wall 34.

The flexible portion 83 is more easily deformed than any of the mounting portion 81, the covering portion 82, and the holding portion 84. Therefore, the covering portion 82 moves between the closed position Pc and the open position Po with the deformation of the flexible portion 83. In other words, the covering portion 82 moves between the closed position Pc and the open position Po while bending the flexible portion 83. When the covering portion 82 is moved, the flexible portion 83 is elastically deformed, for example. Further, the covering portion 82 may be deformed when the covering portion 82 moves between the closed position Pc and the open position Po.

In this embodiment, a plurality of flexible portions 83 connect the corresponding covering portion 82 and the mounting portion 81. However, one flexible portion 83 may connect the plurality of covering portions 82 and the mounting portion 81. For example, in one flexible portion 83, a plurality of intermediate portions 83c may be connected to one first end portion 83a.

As shown in FIG. 2, the holding portion 84 of the present embodiment is a claw-shaped protrusion provided on the covering portion 82. The holding portion 84 is not limited to this example, and may be provided in a portion different from the cover 80. The holding portion 84 has a protruding portion 84a and an engaging portion 84b.

The protruding portion 84a protrudes from the second surface 82b of the covering portion 82. The protrusion 84a is, for example, a substantially rectangular plate-shaped wall extending in the Y direction. The engaging portion 84b is provided on the protruding portion 84a at a position separated from the covering portion 82. When the covering portion 82 is located at the closed position Pc, the width of the engaging portion 84b is larger than the width of the protruding portion 84a in the X direction. For example, the engaging portion 84b has a portion protruding outward in the width direction from the protruding portion 84a. That is, the holding portion 84 is thin at the protruding portion 84a near the covering portion 82 and thick at the engaging portion 84b away from the covering portion 82.

When the covering portion 82 is located at the closed position Pc, the holding portion 84 is arranged between the outer surface 33a of the outer wall 33 of the lower rail 25 and the inner side surface 2bb on the inner side in the width direction of the groove 2b. The holding portion 84 abuts on the outer surface 33a of the outer wall 33 at the engaging portion 84b while elastically deforming the protruding portion 84a. As a result, the holding portion 84 pushes the outer surface 33a of the outer wall 33 by the restoring force of the elastic deformation.

Since the holding portion 84 elastically presses the outer surface 33a of the outer wall 33, when the covering portion 82 moves from the closed position Pc to the open position Po, a static frictional force is generated between the holding portion 84 and the outer wall 33. As a result, when the covering portion 82 is located at the closing position Pc, the holding portion 84 is held by the outer wall 33 of the rail 21 to hold the covering portion 82 at the closing position Pc. In other words, the holding portion 84 holds the covering portion 82 at the closed position Pc by being caught on the outer wall 33 with elastic deformation. The outer wall 33 may also be referred to as a second portion. As described above, the holding portion 84 holds the covering portion 82 at the closed position Pc by snap-fitting using the elastic deformation of the holding portion 84.

The holding method by the holding portion 84 is not limited to the above example. For example, when the covering portion 82 is located at the closed position Pc, the engaging portion 84b may be fitted into a hole or a recess opened in the outer surface 33a of the outer wall 33. In this case, the holding portion 84 limits the movement of the covering portion 82 from the closed position Pc to the open position Po by abutting the engaging portion 84b on the edge of the hole or the recess, and causes the covering portion 82 to be closed at the closed position Pc. Hold on.

Further, the holding portion 84 may abut on the inner side surface 2bb on the inner side in the width direction of the carpet 2d, and at least one of the holding portion 84 and the carpet 2d may be elastically deformed. In this case, when the covering portion 82 moves from the closed position Pc to the open position Po, a static frictional force is generated between the holding portion 84 and the inner side surface 2bb. As a result, the holding portion 84 is held on the floor 2 to hold the covering portion 82 at the closed position Pc. In other words, the holding portion 84 holds the covering portion 82 at the closed position Pc by being caught on the floor 2 with elastic deformation. Floor 2 may also be referred to as the second part.

Further, the holding portion 84 may be sandwiched (held) between the outer surface 33a of the outer wall 33 of the lower rail 25 and the inner side surface 2bb on the inner side in the width direction of the groove 2b of the floor 2. In this case, when the covering portion 82 moves from the closed position Pc to the open position Po, a static frictional force is generated between the holding portion 84 and the outer wall 33, and between the holding portion 84 and the inner side surface 2bb. As a result, the holding portion 84 is held by the rail 21 and the floor 2 to hold the covering portion 82 at the closed position Pc.

As described above, the holding portion 84 is held by at least one of the rail 21 and the floor 2 at a position separated inward in the width direction from the upper wall 34 when the covering portion 82 is located at the closed position Pc. .. Therefore, the mounting portion 81 is mounted on at least one of the rail 21 and the floor 2 on the outer side in the width direction with respect to the rail 21, and the holding portion 84 is mounted on the rail 21 and the floor 2 on the inner side in the width direction with respect to the rail 21. It is held in at least one of them.

The cover 80 described above may be manufactured, for example, by forming a plate shape by two-color molding and then dividing the cover portion 82, the flexible portion 83, and the holding portion 84 into a plurality of parts by cutting. good. According to the manufacturing method, a cover 80 having one mounting portion 81, a plurality of covering portions 82, a plurality of flexible portions 83, and a plurality of holding portions 84 can be easily manufactured.

In the present embodiment, the cover 80 has one mounting portion 81, a plurality of covering portions 82, a plurality of flexible portions 83, and a plurality of holding portions 84. However, the slide rail device 11 may have a plurality of covers 80, each having one mounting portion 81, one covering portion 82, one flexible portion 83, and one holding portion 84. In this case, a plurality of covers 80 are arranged in the Y direction.

In the present embodiment, for example, the covering portion 82 within the range where the slider 22 is located in the Y direction is located at the open position Po. The guide side wall 52 and the guide end wall 53 of the guide member 27 support the covering portion 82 within the range where the slider 22 is located in the Y direction at the open position Po. In other words, the guide side wall 52 and the guide end wall 53 support the covering portion 82 facing (adjacent to each other) in the X direction with the slider 22 at the open position Po. As a result, the guide side wall 52 and the guide end wall 53 prevent the covering portion 82 from returning from the open position Po to the closed position Pc due to its own weight.

At the open position Po, the covering portion 82 is separated from the opening 39 and is supported by the guide member 27. Further, at the open position Po, the covering portion 82 is separated from a member different from the guide member 27, such as the seat 12 and the conversion mechanism 63. In other words, the open position Po is set at a position where the covering portion 82 does not interfere with a member different from the guide member 27. The open position Po is not limited to this example.

Since the opening 39 is exposed in the range where the covering portion 82 is located at the open position Po in the Y direction, the upper rail 26 can be at least partially located at the opening 39. According to another expression, the covering portion 82 is located at the open position Po to avoid the upper rail 26 located at the opening 39.

As the slider 22 moves in the Y direction, the guide end wall 53 of the guide member 27 moves at least one of the plurality of covering portions 82 from the closed position Pc to the open position Po. Hereinafter, the movement of the cover portion 82 from the closed position Pc to the open position Po will be described with a focus on one cover portion 82.

First, as shown in FIG. 5, the slider 22 moves in the Y direction so as to approach the cover portion 82, so that the support surface 53a of the guide end wall 53 comes into contact with the cover portion 82. As described above, the support surface 53a extends diagonally downward from the mounting wall 51. Therefore, when the slider 22 further moves in the Y direction, the covering portion 82 is pushed upward by the support surface 53a.

When the covering portion 82 is pushed by the support surface 53a, the covering portion 82 moves from the closed position Pc to the open position Po while deforming the flexible portion 83. In other words, the covering portion 82 rotates from the closed position Pc to the open position Po by bending the flexible portion 83. The central axis of rotation of the covering portion 82 passes through the inside of the flexible portion 83 or is located in the vicinity of the flexible portion 83, and extends in the substantially Y direction.

The covering portion 82 slides on the guide end wall 53 along the support surface 53a and reaches the guide side wall 52. At least when the covering portion 82 comes into contact with the guide side wall 52, the covering portion 82 reaches the open position Po and is separated from the opening 39.

When the slider 22 further moves in the Y direction, the covering portion 82 slides on the guide side wall 52 along the second support edge 52b and the first support edge 52a. The inclination angle of the covering portion 82 with respect to the upper walls 34 and 35 is such that when the covering portion 82 is supported by the guide end wall 53, when the covering portion 82 is supported by the second support edge 52b, and when the covering portion 82 is supported by the second support edge 52b. When supported by the support edge 52a of 1, the number increases in order.

As described above, the guide end wall 53 pushes the cover portion 82 from the closed position Pc to the open position Po by moving the slider 22 so as to approach the cover portion 82. The guide side wall 52 supports the cover 82 so that the cover 82 is kept in the open position Po.

On the other hand, by moving the slider 22 in the Y direction, at least one of the plurality of covering portions 82 is moved from the open position Po to the closed position Pc. Hereinafter, the movement of the cover portion 82 from the open position Po to the closed position Pc will be described with a focus on one cover portion 82.

First, the slider 22 moves in the Y direction so as to move away from the cover portion 82 located at the open position Po. As a result, the covering portion 82 passes from the first support edge 52a, passes through the second support edge 52b, and reaches the support surface 53a of the guide end wall 53. The covering portion 82 approaches the closed position Pc from the open position Po due to its own weight and the restoring force of the flexible portion 83 while being supported in order by the first support edge 52a, the second support edge 52b, and the support surface 53a.

When the covering portion 82 approaches the closed position Pc from the open position Po, the holding portion 84 comes into contact with, for example, the corner portion between the outer wall 33 and the upper wall 35 of the lower rail 25. For example, the slider 22 is provided with a member that pushes down the covering portion 82 supported by the corner portion. By the member, the covering portion 82 is moved to the closed position Pc with the elastic deformation of the holding portion 84. The holding portion 84 is inserted into the gap between the outer surface 33a and the inner side surface 2bb on the inner side in the width direction while elastically deforming.

When the cover portion 82 reaches the closed position Pc, the slider 22 is separated from the cover portion 82. By moving the slider 22 away from the cover portion 82 in this way, the cover portion 82 moves from the open position Po to the closed position Pc.

In the slide rail device 11 according to the first embodiment described above, the covering portion 82 covers the entire area of the opening 39 in the X direction at the closing position Pc and is separated from the opening 39 at the opening position Po. Since the entire area of the opening 39 in the X direction is covered by one covering portion 82, foreign matter can be suppressed from entering the inside of the rail 21 from the opening 39, and the number of parts of the slide rail device 11 can be reduced. Further, the covering portion 82 is connected to the mounting portion 81 by the flexible portion 83, and moves between the closed position Pc and the open position Po with the deformation of the flexible portion 83. As a result, the covering portion 82 can be smoothly moved between the closed position Pc and the open position Po, and thus the slider 22 can be smoothly moved.

The flexible portion 83 covers a part of the upper wall 34. Therefore, for example, when the flexible portion 83 is stepped on by the passenger of the vehicle 1, the flexible portion 83 is supported by the upper wall 34, so that deformation is suppressed. Therefore, the durability of the cover 80 can be improved.

The flexible portion 83 has a lower rigidity than that of the mounting portion 81 and the covering portion 82. The material of the flexible portion 83 is different from the material of the mounting portion 81 and the material of the covering portion 82. The mounting portion 81, the covering portion 82, and the flexible portion 83 are integrally formed. As a result, the cover 80 including the mounting portion 81, the covering portion 82, and the flexible portion 83 can be treated as an integral part while the flexible portion 83 is easily deformed. Therefore, the slide rail device 11 can be easily assembled and the number of parts of the slide rail device 11 can be reduced.

The mounting portion 81 has an end surface 91c, and is provided with an accommodating groove 91d recessed outward in the width direction from the end surface 91c and an engaging groove 91e recessed in the −Z direction from the inner surface of the accommodating groove 91d. The first end portion 83a, which is a part of the flexible portion 83, is accommodated in the accommodating groove 91d and the engaging groove 91e. Further, the covering portion 82 has an end surface 82c, and is provided with an accommodating groove 82d recessed inward in the width direction from the end surface 82c and an engaging groove 82e recessed in the −Z direction from the inner surface of the accommodating groove 82d. A second end portion 83b, which is a part of the flexible portion 83, is accommodated in the accommodating groove 82d and the engaging groove 82e. As a result, when the flexible portion 83 is about to come off from the mounting portion 81 and the covering portion 82, the flexible portion 83 is caught on the inner surface of the engaging grooves 82e and 91e, and the flexible portion 83 engages with the accommodating grooves 82d and 91d. It is suppressed that the groove 82e and 91e deviate from the groove 82e and 91e.

The covering portion 82 covers the entire area of the opening 39 in the X direction (+ X direction) at the closed position Pc, and is separated from the opening 39 at the open position Po. The holding portion 84 holds the covering portion 82 at the closed position Pc. Since one covering portion 82 covers the entire area of the opening 39 in the X direction and the covering portion 82 is held at the closed position Pc by the holding portion 84, foreign matter is suppressed from entering the inside of the rail 21 from the opening 39. .. For example, the cover 82 is arbitrarily moved to the open position Po by the occupant's mischief, and foreign matter is suppressed from entering the inside of the rail 21 through the exposed opening 39. Further, it is possible to prevent the moving slider 22 and the seat 12 from interfering with the cover portion 82 that has been arbitrarily moved to the open position Po by the occupant's mischief.

The mounting portion 81 is mounted on at least one of the rail 21 and the floor 2 at a position separated from the upper wall 35 in the −X direction opposite to the + X direction. The holding portion 84 is provided on the covering portion 82, and is held by at least one of the rail 21 and the floor 2 at a position separated from the upper wall 34 in the + X direction when the covering portion 82 is located at the closed position Pc. As a result, the arrangement of the portion where the mounting portion 81 is mounted and the portion where the holding portion 84 is held is less likely to interfere with each other, so that the degree of freedom in designing the slide rail device 11 is improved.

The rail 21 has an outer wall 33 and an inner wall 37 extending in the −Z direction, which is orthogonal to the Y direction and intersects the + X direction from the end of the upper wall 35 in the + X direction or the end in the −X direction. The holding portion 84 is held by the outer wall 33 when the covering portion 82 is located at the closed position Pc. Therefore, it is not necessary to provide the upper wall 35 with a structure for holding the holding portion 84, the width of the upper wall 35 in the X direction can be shortened, and the width of the rail 21 in the X direction can be shortened. can.

One of the holding portion 84 provided on the covering portion 82 and the outer wall 33 provided on the rail 21 is caught by the other with elastic deformation, so that the covering portion 82 is held at the closed position Pc. That is, the holding portion 84 holds the covering portion 82 at the closed position Pc by snap-fitting. This makes it possible to simplify the structure of the holding portion 84 and suppress an increase in the cost of the slide rail device 11.

(Second embodiment)
The second embodiment will be described below with reference to FIG. 7. In the following description of the plurality of embodiments, the components having the same functions as the components already described may be designated by the same reference numerals as those described above, and the description may be omitted. .. Further, the plurality of components with the same reference numerals do not necessarily have all the functions and properties in common, and may have different functions and properties according to each embodiment.

FIG. 7 is a cross-sectional view showing a part of the slide rail device 11 of the second embodiment. As shown in FIG. 7, the holding portion 84 of the second embodiment has two hooks 101 and 102. The hooks 101 and 102 may also be referred to as a first portion. The two hooks 101 are claw-shaped protrusions provided on the covering portion 82 and protruding from the second surface 82b of the covering portion 82 at positions separated from each other in the X direction.

When the cover portion 82 is located at the closed position Pc, the hook 101 is held by the outer wall 33 of the lower rail 25 as in the holding portion 84 of the first embodiment. That is, the hook 101 is held by the outer wall 33 by the static friction force by elastically pressing the outer surface 33a of the outer wall 33. In other words, the hook 101 holds the covering portion 82 at the closed position Pc by being caught on the outer wall 33 with elastic deformation. The hook 101 may be fitted into a hole or a recess opened in the outer surface 33a of the outer wall 33.

The hook 102 is separated from the hook 101 outward in the width direction. When the cover 82 is located at the closed position Pc, the hook 102 is held by the inner wall 37 of the lower rail 25. In the second embodiment, the outer wall 33 and the inner wall 37 may also be referred to as a third wall.

The hook 102 abuts on the inner wall 37 while elastically deforming. As a result, the hook 102 pushes the inner wall 37 by the restoring force of the elastic deformation. Since the hook 102 elastically presses the inner wall 37, a static frictional force is generated between the hook 102 and the inner wall 37 when the covering portion 82 moves from the closed position Pc to the open position Po. As a result, the hook 102 is held by the inner wall 37 when the covering portion 82 is located at the closing position Pc, thereby holding the covering portion 82 at the closing position Pc. In other words, the hook 102 is caught on the inner wall 37 with elastic deformation, thereby holding the covering portion 82 at the closed position Pc.

The hooks 101 and 102 of the second embodiment hold the covering portion 82 at the closed position Pc by a snap fit utilizing the elasticity of the hooks 101 and 102. Further, the outer wall 33, the upper wall 35, and the inner wall 37 of the lower rail 25 are sandwiched (held) between the two hooks 101 and 102.

When the slider 22 moves in the Y direction so as to approach the cover portion 82, the guide end wall 53 of the guide member 27 abuts on the cover portion 82 or the hook 102. When the guide end wall 53 abuts on the cover portion 82, the guide end wall 53 pushes the cover portion 82 in the + Z direction as the slider 22 moves. When the cover portion 82 is pushed up in the + Z direction, the hook 102 is pulled up to the cover portion 82 and comes off from the inner wall 37. On the other hand, when the guide end wall 53 abuts on the hook 102, the guide end wall 53 pushes the hook 102 outward in the width direction as the slider 22 moves. As a result, the hook 102 is elastically deformed so as to be separated from the inner wall 37. That is, the guide member 27 releases the holding of the covering portion 82 by the holding portion 84 as the slider 22 moves. The guide member 27 may also be referred to as a release portion.

When the covering portion 82 that moves from the closed position Pc to the open position Po rotates, the hook 101 is tilted so that the tip of the hook 101 is separated from the outer wall 33. Therefore, when the covering portion 82 moves from the closed position Pc to the open position Po, the force with which the hook 101 pushes the outer wall 33 is slightly increased, maintained, or decreased.

On the other hand, when the covering portion 82 that moves from the closed position Pc to the open position Po rotates, the hook 102 tilts so that the tip of the hook 102 approaches the inner wall 37. Therefore, when the covering portion 82 moves from the closed position Pc to the open position Po, the force with which the hook 102 pushes the inner wall 37 is greatly increased. However, in the second embodiment, when the guide end wall 53 directly abuts on the hook 102, the guide end wall 53 separates the hook 102 from the inner wall 37 in advance, so that the hook 102 is desired for the covering portion 82. Obstruction of movement is suppressed.

In the second embodiment, the flexible portion 83 is provided longer than in the first embodiment. Specifically, when the covering portion 82 is located at the closed position Pc, the length of the flexible portion 83 in the X direction is between the inner side surface 2bb on the outer side in the width direction of the groove 2b of the floor 2 and the outer wall 32. Longer than the distance. As a result, the covering portion 82 can be smoothly moved between the closed position Pc and the open position Po, and thus the slider 22 can be smoothly moved.

When the covering portion 82 is located at the closed position Pc, the flexible portion 83 is supported by the base portion 91 of the mounting portion 81. As a result, for example, when the flexible portion 83 is stepped on, the flexible portion 83 is supported by the mounting portion 81, so that deformation is suppressed. Therefore, the durability of the cover 80 can be improved.

In the slide rail device 11 of the second embodiment described above, the holding portion 84 has a hook 101 that abuts on the outer wall 33 and a hook 102 that abuts on the inner wall 37 at the closed position Pc. As a result, as compared with the first embodiment, the covering portion 82 is moved to the open position Po by the passenger's mischief, and foreign matter enters the inside of the rail 21 from the exposed opening 39. Can be suppressed.

The slider 22 has a guide member 27 that releases the holding of the covering portion 82 by the holding portion 84 as the slider 22 moves. As a result, the cover portion 82 can move from the closed position Pc to the open position Po with the movement of the slider 22, so that the slider 22 and the cover portion 82 move smoothly.

(Third embodiment)
Hereinafter, the third embodiment will be described with reference to FIGS. 8 and 9. FIG. 8 is a cross-sectional view showing a part of the slide rail device 11 of the third embodiment. FIG. 9 is a cross-sectional view showing a part of the slide rail device 11 in which the covering portion 82 is located at the open position Po in the third embodiment.

In the third embodiment, the mounting portion 81, the plurality of covering portions 82, the plurality of flexible portions 83, and the plurality of holding portions 84 are made of, for example, a synthetic resin such as polyacetal (POM). In other words, the mounting portion 81, the covering portion 82, the flexible portion 83, and the holding portion 84 are integrally formed of one material. The mounting portion 81, the covering portion 82, the flexible portion 83, and the holding portion 84 may be formed of a plurality of materials or functionally graded materials.

The flexible portion 83 has a thin-walled portion 121. The thin-walled portion 121 is a portion of the integrally formed cover 80 that is thinner than the other portions. For example, the thin wall portion 121 is thinner than the cover portion 82 and thinner than the base portion 91 of the mounting portion 81. Therefore, the thin-walled portion 121 has a lower rigidity than that of the mounting portion 81 and the covering portion 82.

The thin-walled portion 121 connects the covering portion 82 and the base portion 91 of the mounting portion 81. The thin portion 121 extends in the substantially Y direction. For example, by providing a groove extending in the substantially Y direction on a plate-shaped wall having a substantially constant thickness, the wall is divided into a base portion 91 of the mounting portion 81 and a covering portion 82 by the groove. Further, the portion provided with the groove becomes the thin-walled portion 121 of the flexible portion 83.

As shown in FIGS. 8 and 9, the covering portion 82 moves between the closed position Pc and the open position Po with the deformation of the thin-walled portion 121. In other words, the covering portion 82 moves between the closed position Pc and the open position Po while bending the thin-walled portion 121.

The thin portion 121 is separated from the upper wall 34. As a result, when the covering portion 82 moves between the closed position Pc and the open position Po, it is possible to prevent the mounting portion 81 and the covering portion 82 from interfering with each other. Further, the first surface 82a of the covering portion 82 and the upper surface 91b of the base portion 91 of the mounting portion 81 are smoothly continuous with each other via the flexible portion 83. This improves the appearance of the cover 80.

The holding portion 84 has a first snap button 125 and a second snap button 126. The first snap button 125 may also be referred to as the second part. The second snap button 126 may also be referred to as the first portion. The first snap button 125 is provided on the upper wall 35 of the lower rail 25. The second snap button 126 is provided on the second surface 82b of the cover 82.

The first snap button 125 is a male snap button and projects from the outer surface 35a of the upper wall 35. The first snap button 125 may be attached to the upper wall 35, or may be integrally provided on the upper wall 35 by, for example, pressing. Further, the first snap button 125 may be a female snap button.

The second snap button 126 is a female snap button and includes a recess recessed from the second surface 82b of the cover 82. The second snap button 126 may be provided on the covering portion 82 by injection molding, for example, or may be attached to the covering portion 82. Further, the second snap button 126 may be a male snap button.

When the covering portion 82 is located at the closed position Pc, the first snap button 125 and the second snap button 126 are fitted to each other. As a result, the holding portion 84 holds the covering portion 82 at the closed position Pc by snap-fitting.

The first snap button 125 includes, for example, a substantially columnar protrusion provided with a recess on the outer peripheral surface. The second snap button 126 is provided with, for example, a substantially circular recess capable of accommodating the protrusion, and has a claw protruding from the inner peripheral surface of the recess. The protrusion is fitted into the recess while elastically deforming the claw. By fitting the claw into the recess of the protrusion, the protrusion is prevented from coming off the recess. In other words, the second snap button 126 is hooked on the first snap button 125 with elastic deformation, thereby holding the cover portion 82 at the closed position Pc. As described above, the first snap button 125 and the second snap button 126 hold the covering portion 82 at the closed position Pc by the snap fit utilizing the elastic deformation of the claw.

In the slide rail device 11 of the third embodiment described above, the mounting portion 81, the covering portion 82, and the flexible portion 83 are integrally formed. The flexible portion 83 is thinner than the covering portion 82. By forming the flexible portion 83 thinner than the covering portion 82, the flexible portion 83 can be made less rigid than either the mounting portion 81 or the covering portion 82. Therefore, the covering portion 82 can move with the deformation of the flexible portion 83. Therefore, for example, the flexible portion can be easily deformed while the mounting portion 81, the cover portion 82, and the flexible portion 83 are formed of the same material, and the cost of the slide rail device 11 can be reduced.

As described above, the holding portion 84 may be a claw-shaped protrusion of the first and second embodiments, or may be a snap button of the third embodiment. Further, the holding unit 84 is not limited to the above examples, and may include the following examples.

For example, the holding portion 84 may have a magnet provided on one of the covering portion 82 and the floor 2 and a metal provided on the other. By attracting the metal by the magnetic force of the magnet, the holding portion 84 can hold the covering portion 82 at the closed position Pc. Further, an electromagnet may be applied as the magnet. In this case, for example, the ECU stops the generation of the magnetic force by the electromagnet to release the holding of the covering portion 82 by the holding portion 84.

For example, the holding portion 84 may have a pair of hook-and-loop fasteners provided on the covering portion 82 and the floor 2. By sticking the hook-and-loop fastener provided on the cover portion 82 and the hook-and-loop fastener provided on the floor 2, the holding portion 84 can hold the cover portion 82 at the closed position Pc.

For example, the holding portion 84 may have a suction device provided on one of the covering portion 82 and the floor 2. The suction device is attracted to the other of the covering portion 82 and the floor 2, so that the holding portion 84 can hold the covering portion 82 at the closed position Pc.

The covering portion 226 of the closed position Pc may expose the upper walls 34 and 35 as long as it covers the entire area of the opening 39 in the X direction.

In the Y direction, the length of the covering portion 226 is shorter than any of the lengths of the opening 39, the upper wall 34, and the upper wall 35. Therefore, in the Y direction, one covering portion 226 covers a part of the opening 39, a part of the upper wall 34, and a part of the upper wall 35.

As shown in FIG. 15, at the open position Po, the covering portion 226 is separated from the opening 39 of the lower rail 25. The covering portion 226 of the open position Po extends away from the opening 39 as it goes away from the mounting portion 225. In other words, the covering portion 226 extends upwardly or diagonally upward from the mounting portion 225. Therefore, the covering portion 226 of the open position Po is exposed without covering the opening 39.

As shown in FIG. 13, the mounting portion 225 has a contact surface 225a. The contact surface 225a faces in the substantially −Z direction at the closed position Pc. The contact surface 225a faces the receiving surface 216a of the receiving portion 216 via the space Da in the Z direction.

Normally, the receiving portion 216 including the receiving surface 216a is separated from the mounting portion 225. By providing the recess 217, the receiving portion 216 can avoid the mounting portion 225 that rotates between the closed position Pc and the open position Po, and can suppress interference with the mounting portion 225.

An insertion hole 227 is provided in the mounting portion 225. The insertion hole 227 may also be referred to as an insertion opening. The insertion hole 227 is a substantially oval hole that penetrates the mounting portion 225 in the Y direction. In the present embodiment, when the covering portion 226 is located at the closed position Pc, the length of the insertion hole 227 in the Z direction (−Z direction) is longer than the length of the insertion hole 227 in the X direction (+ X direction).

By passing the mounting shaft 205 through the insertion hole 227, the mounting portion 225 is rotatably mounted on the mounting shaft 205 around the mounting shaft 205. In this way, the mounting portion 225 is mounted on the mounting shaft 205 of the mounting tool 200 of the rail 21.

The insertion hole 227 is provided in the mounting portion 225 so that the covering portion 226 is opened in the −Z direction when the covering portion 226 is located at the closed position Pc. For example, the insertion hole 227 is a groove that opens in the contact surface 225a of the mounting portion 225. Therefore, the inner surface of the insertion hole 227 is formed in a substantially U shape. The insertion hole 227 is not limited to this example, and may be, for example, a hole opened only in the Y direction.

When the covering portion 226 is located at the closed position Pc, the end portion 227a of the insertion hole 227 in the −Z direction opens to the contact surface 225a of the mounting portion 225. In other words, the end portion 227a of the insertion hole 227 is open to the outside of the mounting portion 225. When the cover portion 226 is located at the closed position Pc, the length (width) of the end portion 227a in the X direction is shorter than the diameter of the mounting shaft 205. Therefore, the mounting shaft 205 is held inside the insertion hole 227.

The mounting portion 225 is detachably attached to the mounting shaft 205 by a snap fit. For example, the mounting portion 225 is elastically deformed so that the end portion 227a expands, and the mounting shaft 205 is attached to and detached from the insertion hole 227 through the end portion 227a. As a result, the mounting portion 225 is mounted on the rail 21 so as to be removable from the respective positions of the plurality of covers 220.

The mounting portion 225 has a bottom surface 227b of the insertion hole 227. The bottom surface 227b is provided at the end of the insertion hole 227 in the + Z direction when the covering portion 226 is located at the closed position Pc. The bottom surface 227b faces in the −Z direction when the covering portion 226 is located at the closed position Pc.

The upper portion 205a of the mounting shaft 205 facing in the + Z direction faces the bottom surface 227b of the insertion hole 227 via the space Db. In the Z direction, the length of the spacing Db is longer than the length of the spacing Da. The + Z direction may also be referred to as a fourth direction. On the other hand, the mounting shaft 205 passing through the insertion hole 227 is supported in the X direction on the inner surface of the insertion hole 227 when the covering portion 226 is located at the closed position Pc. Therefore, the mounting shaft 205 limits the movement of the mounting portion 225 in the X direction when the covering portion 226 is located at the closed position Pc.

The covering portion 226 has a lower surface 226a, an upper surface 226b, and a side surface 226c. The lower surface 226a of the first cover 221 may also be referred to as the first surface. The upper surface 226b of the first cover 221 may also be referred to as a second surface. The lower surface 226a of the second cover 222 may also be referred to as a fourth surface. The upper surface 226b of the second cover 222 may also be referred to as a fifth surface.

The lower surface 226a faces the rail 21 when the covering portion 226 is located at the closed position Pc. For example, the lower surface 226a faces the outer surfaces 34a, 35a of the upper walls 34, 35 of the lower rail 25 by facing the −Z direction when the covering portion 226 is located at the closed position Pc.

The lower surface 226a is provided with a plurality of substantially hexagonal recesses and ribs forming a honeycomb structure. The honeycomb structure can suppress the occurrence of sink marks due to, for example, injection molding of the cover 220, and can reduce the weight of the cover 220.

The upper surface 226b is a substantially flat surface located on the opposite side of the lower surface 226a. Therefore, the upper surface 226b faces in the + Z direction when the covering portion 226 is located at the closed position Pc. The + Z direction may also be referred to as a second direction. The upper surface 226b is continuous with the outer peripheral surface of the substantially columnar mounting portion 225 and extends in the tangential direction of the outer peripheral surface. The upper surface 226b is not limited to this example.

When the covering portion 226 is located at the closed position Pc, the length of the upper surface 226b in the X direction is longer than the length of the lower surface 226a in the X direction. The lengths of the lower surface 226a and the upper surface 226b are not limited to this example.

The side surface 226c extends in the substantially + Z direction from the end of the lower surface 226a in the + X direction when the covering portion 226 is located at the closed position Pc. The side surface 226c faces in the + X direction when the covering portion 226 is located at the closed position Pc.

An engaging groove 226d is provided on the side surface 226c. The engagement groove 226d may also be referred to as a first portion. The engaging groove 226d is recessed from the side surface 226c and extends in the Y direction. The claw 204c of the hook member 204 can be inserted into the engaging groove 226d.

FIG. 18 is a perspective view showing the first cover 221 of the fourth embodiment. FIG. 19 is a perspective view showing the second cover 222 of the fourth embodiment.

As shown in FIG. 18, the cover portion 226 of the first cover 221 further has two support surfaces 226e. The support surface 226e may also be referred to as a third surface. The support surface 226e is a substantially flat surface located on the opposite side of the lower surface 226a, like the upper surface 226b of the first cover 221. The support surface 226e faces in the + Z direction when the covering portion 226 is located at the closed position Pc. That is, the support surface 226e is a surface substantially parallel to the upper surface 226b. The direction in which the support surface 226e faces and the direction in which the upper surface 226b faces may be different from each other.

The upper surface 226b and the support surface 226e are adjacent to each other in the Y direction. That is, in the Y direction, no surface is provided between the upper surface 226b and the support surface 226e so as to face substantially the same direction as the upper surface 226b and the support surface 226e, except for a chamfered curved surface, for example. Not limited to this example, another surface may be provided between the upper surface 226b and the support surface 226e.

The support surface 226e is closer to the lower surface 226a than the upper surface 226b. That is, the support surface 226e is recessed from the upper surface 226b. In the Y direction, the upper surface 226b is located between the two support surfaces 226e. In the Y direction, the length of the lower surface 226a is longer than the length of each of the upper surface 226b and the support surface 226e.

The cover portion 226 of the first cover 221 has a main portion 221a and two support portions 221b. The main portion 221a may also be referred to as a first portion. The support portion 221b may also be referred to as a second portion. The support portion 221b may also be referred to as a fin portion. The main portion 221a is formed in the shape of a substantially rectangular plate, and has a part of the lower surface 226a and the upper surface 226b. That is, the main portion 221a is a portion of the first cover 221 between the lower surface 226a and the upper surface 226b.

The support portion 221b is formed in the shape of a substantially rectangular plate thinner than the main portion 221a. The support portion 221b has a part of the lower surface 226a and a support surface 226e. That is, the support portion 221b is a portion of the first cover 221 between the lower surface 226a and the support surface 226e. The two support portions 221b project from both ends of the main portion 221a in the Y direction. The support portion 221b projects from the main portion 221a toward the cover portion 226 of the adjacent second cover 222.

When the covering portion 226 of the first cover 221 is located at the closed position Pc, both the main portion 221a and the two supporting portions 221b cover the upper walls 34, 35 and the opening 39 of the lower rail 25. The main portion 221a and the support portion 221b are not limited to this example. For example, the support portion 221b may be exposed without covering the upper walls 34 and 35 while covering the opening 39.

As shown in FIG. 19, the covering portion 226 of the second cover 222 further has two concave surfaces 226f. The concave surface 226f may also be referred to as a sixth surface. The concave surface 226f faces the rail 21 when the covering portion 226 is located at the closed position Pc, like the lower surface 226a of the second cover 222. For example, the concave surface 226f faces the outer surfaces 34a and 35a of the upper walls 34 and 35 of the lower rail 25 by facing the −Z direction when the covering portion 226 is located at the closed position Pc. The concave surface 226f is a surface substantially parallel to the lower surface 226a. The direction in which the concave surface 226f faces and the direction in which the lower surface 226a faces may be different from each other.

The concave surface 226f is closer to the upper surface 226b than the lower surface 226a. That is, the concave surface 226f is recessed from the lower surface 226a. In the Y direction, the lower surface 226a is located between the two concave surfaces 226f. In the Y direction, the length of the upper surface 226b is longer than the length of each of the lower surface 226a and the concave surface 226f.

The cover portion 226 of the second cover 222 has a main portion 222a and two extension portions 222b. The main portion 222a is formed in the shape of a substantially rectangular plate, and has a lower surface 226a and a part of the upper surface 226b. That is, the main portion 222a is a portion of the second cover 222 between the lower surface 226a and the upper surface 226b.

The extending portion 222b is formed in the shape of a substantially rectangular plate thinner than the main portion 222a. The extending portion 222b has a part of the upper surface 226b and a concave surface 226f. That is, the extended portion 222b is a portion of the second cover 222 between the upper surface 226b and the concave surface 226f. The two extension portions 222b project from both ends of the main portion 222a in the Y direction.

When the covering portion 226 of the second cover 222 is located at the closed position Pc, both the main portion 222a and the two extending portions 222b cover the upper walls 34, 35 and the opening 39 of the lower rail 25. The main portion 222a and the extension portion 222b are not limited to this example. For example, the extension portion 222b may be exposed while covering the opening 39 but not covering the upper walls 34 and 35.

As shown in FIG. 17, the extension portion 222b of the second cover 222 located at the closed position Pc covers the support portion 221b of the first cover 221 located at the closed position Pc. In other words, the extension portion 222b of the second cover 222 located at the closed position Pc covers the support portion 221b covering the opening 39 of the first cover 221 located at the closed position Pc.

The support surface 226e of the first cover 221 and the concave surface 226f of the second cover 222 face each other when the first cover 221 and the second cover 222 are located at the closed position Pc. In the present embodiment, the support surface 226e contacts and supports the concave surface 226f when the first cover 221 and the second cover 222 are located at the closed position Pc. The support surface 226e may be separated from the concave surface 226f when the first cover 221 and the second cover 222 are located at the closed position Pc.

The extension 222b of one of the two second covers 222 adjacent to the first cover 221 supports one of the first covers 221 located at the closed position Pc when the one is located at the closed position Pc. Cover the portion 221b. Further, the extension portion 222b of the other of the two second covers 222 covers the other support portion 221b of the first cover 221 located at the closing position Pc when the other is located at the closing position Pc.

When the first cover 221 and the second cover 222 are located at the closed position Pc, there is a gap between the main portion 221a of the first cover 221 and the extension portion 222b of the second cover 222. There is. The gap is closed by the support portion 221b of the first cover 221. Therefore, it is possible to prevent the opening 39 from being exposed between the main portion 221a of the first cover 221 and the extension portion 222b of the second cover 222.

The thickness of the main portion 221a of the first cover 221 is substantially equal to the thickness of the main portion 222a of the second cover 222. The thickness of the main portion 221a is the length between the lower surface 226a and the upper surface 226b of the first cover 221. The thickness of the main portion 222a is the length between the lower surface 226a and the upper surface 226b of the second cover 222.

Further, the thickness of each of the main portions 221a and 222a is substantially equal to the sum of the thickness of the support portion 221b of the first cover 221 and the thickness of the extension portion 222b of the second cover 222. The thickness of the support portion 221b is the length between the lower surface 226a and the support surface 226e. The thickness of the extending portion 222b is the length between the upper surface 226b and the concave surface 226f. Therefore, when the first cover 221 and the second cover 222 are located at the closed position Pc, the upper surface 226b of the first cover 221 and the second cover 222 are arranged substantially flat.

In the present embodiment, the upper surface 226b of the first cover 221 and the second cover 222 located at the closed position Pc forms a substantially flat surface. Specifically, the upper surface 226b of the first cover 221 located at the closed position Pc and the upper surface 226b of the second cover 222 located at the closed position Pc are located at substantially the same position in the + Z direction. Further, the upper surface 226b and the support surface 226e of the first cover 221 located at the closed position Pc and the upper surface 226b of the second cover 222 located at the closed position Pc are substantially flat surfaces facing the + Z direction. The first cover 221 and the second cover 222 located at the closed position Pc are between the upper surface 226b of the first cover 221 and the upper surface 226b of the second cover 222, except for the support surface 226e. There is no part facing the + Z direction. In other words, no concave surface or convex surface is provided between the upper surface 226b of the first cover 221 and the upper surface 226b of the second cover 222. Therefore, the upper surface 226b of the first cover 221 and the upper surface 226b of the second cover 222 are a series of substantially flat surfaces except for the gap between the first cover 221 and the second cover 222. Form a surface. A concave surface or a convex surface may be provided between the upper surface 226b of the first cover 221 and the upper surface 226b of the second cover 222.

When the first cover 221 is located at the closed position Pc, the adjacent second cover 222 may be located at the open position Po. In this case, the extension portion 222b of the second cover 222 located at the open position Po exposes the support portion 221b of the first cover 221 located at the closed position Pc without covering it.

As shown in FIG. 18, each of the first covers 221 further has two protrusions 228. The second cover 222 may have a protrusion 228. The protruding portion 228 projects from the mounting portion 225 of the first cover 221 toward the mounting portion 225 of the adjacent second cover 222.

In the present embodiment, the protruding portion 228 is formed by extending the mounting portion 225 in the Y direction beyond the main portion 221a. According to another expression, in the Y direction, the length of the mounting portion 225 including the protruding portion 228 is set to be longer than the length of the main portion 221a. The protruding portion 228 is not limited to this example, and may have a shape different from that of the mounting portion 225.

In the Y direction, the length of the support portion 221b is longer than the length of the protrusion 228. Therefore, the support portion 221b protrudes in the Y direction beyond the protruding portion 228. Further, in the Y direction, the total length of the mounting portion 225 and the protruding portion 228 of the first cover 221 is shorter than the length of the mounting portion 225 of the second cover 222.

The protrusion 228 abuts on the mounting portion 225 of the adjacent second cover 222 to limit the covering portion 226 of the first cover 221 and the covering portion 226 of the adjacent second cover 222 from approaching each other. do. For example, even if the first cover 221 or the second cover 222 is slightly tilted about an axis orthogonal to the lower surface 226a, the main portion 222a of the second cover 222 rides on the support portion 221b of the first cover 221. Is suppressed.

As shown in FIG. 13, the elastic member 229 is attached to the outer surfaces 34a and 35a of the upper walls 34 and 35 of the lower rail 25. The elastic member 229 is made of, for example, an elastomer such as synthetic rubber.

The lower surface 226a of the covering portion 226 located at the closed position Pc comes into contact with the elastic member 229. As a result, the elastic member 229 supports the covering portion 226 of the closed position Pc at a position separated from the upper walls 34 and 35 of the lower rail 25 in the + Z direction. In other words, the rail 21 supports the lower surface 226a of the first cover 221 located at the closed position Pc and the lower surface 226a of the second cover 222 located at the closed position Pc via the elastic member 229. The covering portion 226 may be directly supported by the upper walls 34 and 35.

The seat device 10 of the fourth embodiment has a holding portion 230 including a hook member 204 and an engaging groove 226d. As described above, the hook member 204 is provided on the rail 21 and the engaging groove 226d is provided on the covering portion 226.

While the cover 220 rotates from the open position Po to the closed position Pc, the claw 204c is caught in the engaging groove 226d with elastic deformation of the hook member 204. As a result, the holding portion 230 holds the covering portion 226 of the cover 220 at the closed position Pc.

The hook member 204 can be elastically deformed between the normal state Sr shown by the solid line in FIG. 13 and the deformed state Sd shown by the two-dot chain line in FIG. The normal state Sr may also be referred to as a first state. The deformed state Sd may also be referred to as a second state.

The hook member 204 is in the normal state Sr, for example, when it is not subjected to an external force. The hook member 204 in the normal state Sr can be caught in the engaging groove 226d when the covering portion 226 of the cover 220 is located at the closed position Pc. In other words, the state in which the claw 204c is caught in the engaging groove 226d and the state in which the hook member 204 has substantially the same shape as the state are defined as the normal state Sr.

As shown in FIGS. 13 and 14, the hook member 204 in the deformed state Sd is elastically deformed so that the claw 204c is at least partially disengaged from the engaging groove 226d. That is, the hook member 204 in the deformed state Sd is separated from the engaging groove 226d than the normal state Sr when the covering portion 226 is located at the closed position Pc.

While the cover portion 226 rotates from the open position Po to the closed position Pc, the hook member 204 is elastically deformed from the normal state Sr to the deformed state Sd. This prevents the claw 204c of the hook member 204 from hindering the movement of the covering portion 226 from the open position Po to the closed position Pc. When the covering portion 226 moves to the closed position Pc, the hook member 204 returns from the deformed state Sd to the normal state Sr, and the claw 204c is caught in the engaging groove 226d. As a result, the holding portion 230 holds the covering portion 226 at the closed position Pc.

While the covering portion 226 moves from the closed position Pc to the open position Po, the hook member 204 is elastically deformed from the normal state Sr to the deformed state Sd. This prevents the claw 204c of the hook member 204 from hindering the movement of the covering portion 226 from the closed position Pc to the open position Po.

The end portion 247a of the return portion 247 on the inner side in the width direction is continuous from the end portion 246a of the sliding portion 246. The end portion 247a of the return portion 247 extends obliquely with respect to the Y direction so as to move away from the side wall 241 as the distance from the sliding portion 246 increases.

The end portion 246a of the sliding portion 246 and the end portion 247a of the return portion 247 are made of a cushioning material such as urethane sponge. The ends 246a and 247a may be made of other materials.

As shown in FIG. 12, the first pressing portion 245 is provided at the end portion 243a of the end wall 243 in the −Z direction. The first pressing portion 245 may be provided in another portion. In the Y direction, the guide 244 is located between the two first pressing portions 245. In the Y direction, the two first pressing portions 245 are separated from the guide 244. Further, in the Y direction, the first pressing portion 245 is separated from the guide end wall 53 of the guide member 27.

The first pressing portion 245 is in contact with the upper surface 226b of the covering portion 226 located at the closed position Pc, or is slightly separated from the upper surface 226b. The first pressing portion 245 is made of a cushioning material such as urethane sponge. The first pressing portion 245 may be made of another material.

As shown in FIG. 11, the slider 22 of the fourth embodiment further has a second pressing portion 250. In the present embodiment, the second pressing portion 250 is provided on the guide member 27. The second pressing portion 250 is not limited to this example, and may be provided on, for example, the upper rail 26.

The second pressing portion 250 is connected to the end portion of the mounting wall 51 on the inner side in the width direction (+ X direction). Therefore, the mounting wall 51 is located between the guide side wall 52 and the second pressing portion 250 in the width direction.

The second pressing portion 250 has a first edge portion 251 and two second edge portions 252. The first edge portion 251 and the second edge portion 252 are the ends of the second pressing portion 250 on the inner side in the width direction.

In the Y direction, the first edge 251 is located between the two second edges 252. The first edge portion 251 is continuous with the second edge portion 252. As shown in FIG. 14, in the Z direction, the first edge portion 251 and the second edge portion 252 are arranged at substantially the same positions as the claws 204c of the hook member 204 in the normal state Sr and the deformed state Sd.

The first edge portion 251 extends substantially linearly in the Y direction. The first edge portion 251 may extend in a curved shape. In the X direction, the first edge portion 251 is separated inward in the width direction from the claw 204c of the hook member 204 in the normal state Sr.

As shown in FIG. 11, the second edge portion 252 extends diagonally with respect to the Y direction. The second edge portion 252 may extend linearly or curvedly. The second edge portion 252 extends closer to the mounting shaft 205 as the distance from the first edge portion 251 increases.

The first edge portion 251 and the second edge portion 252 of the second pressing portion 250 abut on the claw 204c of the hook member 204. The hook member 204 is elastically deformed to the deformed state Sd when the claw 204c abuts on the second pressing portion 250.

The second pressing portion 250 elastically deforms not only the portion of the hook member 204 that abuts on the first edge portion 251 and the second edge portion 252 but also the portion within a predetermined range to the deformed state Sd. In the Y direction, the length of the portion of the hook member 204 elastically deformed to the deformed state Sd by the second pressing portion 250 is longer than the distance between the two first pressing portions 245.

At the position (coordinates) where the guide end wall 53 is provided in the Y direction, the hook member 204 is elastically deformed from the normal state Sr to the deformed state Sd by the second pressing portion 250. Further, at the position (coordinates) where the first pressing portion 245 is provided in the Y direction, the hook member 204 is elastically deformed from the normal state Sr to the deformed state Sd by the second pressing portion 250.

In the Y direction, a plurality of hook members 204 may be arranged side by side, and two adjacent hook members 204 may not be connected to each other. In this case, the other hook member 204 adjacent to the hook member 204 in the deformed state Sd is in the normal state Sr.

The end 252a of the second edge portion 252 on the outer side in the width direction (−X direction) is located at substantially the same position as the claw 204c of the hook member 204 in the normal state Sr, or is separated from the outer side in the width direction. Therefore, while the second pressing portion 250 moves closer to the hook member 204 in the normal state Sr, the second edge portion 252 does not get caught in the hook member 204 in the normal state Sr, and the claw of the hook member 204 The 204c can be elastically deformed from the normal state Sr to the deformed state Sd.

As shown in FIG. 10, in the present embodiment, for example, the covering portion 226 within the range where the slider 22 is located in the Y direction is located at the open position Po. The guide end wall 53 of the guide member 27 and the guide 244 of the shield 240 support the covering portion 226 within the range where the slider 22 is located in the Y direction at the open position Po. In other words, the guide end wall 53 and the guide 244 support the covering portion 226 facing (adjacent, lining up) in the X direction with the slider 22 at the open position Po. As a result, the guide end wall 53 and the guide 244 prevent the covering portion 226 from returning from the open position Po to the closed position Pc due to its own weight.

For example, the guide end wall 53 supports a cover 226 rotated less than 90 ° from the blockage position Pc. The end portion 246a of the sliding portion 246 of the guide 244 supports the covering portion 226 rotated by more than 90 ° from the closed position Pc.

At the open position Po, the covering portion 226 is separated from the opening 39 and is supported by the guide end wall 53 or the guide 244. Further, at the open position Po, the covering portion 226 is separated from a member different from the guide member 27 and the shield 240, such as the sheet 12 and the conversion mechanism 63. In other words, the open position Po is set at a position where the covering portion 226 does not interfere with a member different from the guide member 27 and the shield 240. The open position Po is not limited to this example.

Since the opening 39 is exposed in the range where the covering portion 226 is located at the open position Po in the Y direction, the upper rail 26 can be at least partially located at the opening 39. According to another expression, the covering portion 226 is located at the open position Po to avoid the upper rail 26 located at the opening 39.

As the slider 22 moves in the Y direction, the guide end wall 53 of the guide member 27 moves at least one of the plurality of covering portions 226 from the closed position Pc to the open position Po. Hereinafter, the movement of the cover portion 226 from the closed position Pc to the open position Po will be described with a focus on one cover portion 226.

FIG. 20 is a perspective view showing a part of the slide rail device 11 of the fourth embodiment. As shown in FIG. 20, the slider 22 moves in the Y direction so as to approach the cover portion 226 of the first cover 221 so that the support surface 53a of the guide end wall 53 comes into contact with the cover portion 226. The support surface 53a extends diagonally downward from the mounting wall 51. Therefore, when the slider 22 further moves in the Y direction, the covering portion 226 is pushed upward by the support surface 53a.

The second pressing portion 250 is in the normal state Sr so that the hook member 204 is in the deformed state Sd at the position where the support surface 53a of the guide end wall 53 in the Y direction pushes the covering portion 226 with the movement of the slider 22. The hook member 204 of the above is elastically deformed to the deformed state Sd. Therefore, when the support surface 53a pushes the covering portion 226, the claw 204c of the hook member 204 is disengaged from the engaging groove 226d of the covering portion 226.

As described above, the holding portion 226 is released from the holding portion 226 by the holding portion 230 by the second pressing portion 250. Therefore, when the cover portion 226 is pushed against the support surface 53a, the first cover 221 including the cover portion 226 rotates around the mounting shaft 205 from the closed position Pc toward the open position Po.

As the first cover 221 rotates, the support portion 221b of the first cover 221 pushes the extension portion 222b of the adjacent second cover 222 upward. When the extension portion 222b is pushed by the support portion 221b, the second cover 222 including the extension portion 222b rotates around the mounting shaft 205 from the closed position Pc toward the open position Po. In this way, the first cover 221 rotates from the closed position Pc toward the open position Po together with the adjacent second cover 222.

While rotating from the closed position Pc to the open position Po, the second cover 222 is separated from the first cover 221 that is separated from the support surface 53a. That is, the first cover 221 that is separated from the support surface 53a is not rotated by the second cover 222 and stays at the closed position Pc.

The cover portion 226 of the first cover 221 slides on the guide end wall 53 along the support surface 53a and reaches the guide side wall 52. At least when the cover portion 226 comes into contact with the guide side wall 52, the cover portion 226 reaches the open position Po and is separated from the opening 39.

When the slider 22 further moves in the Y direction, the covering portion 226 slides on the guide side wall 52 along the second support edge 52b toward the first support edge 52a. The inclination angle of the covering portion 226 with respect to the upper walls 34 and 35 is such that when the covering portion 226 is supported by the guide end wall 53, when the covering portion 226 is supported by the second support edge 52b, and when the covering portion 226 is supported by the second support edge 52b. When the support edge 52a of 1 is reached, the number increases in order.

As shown in FIG. 15, the first support edge 52a of the fourth embodiment is separated from the mounting shaft 205 in the width direction outward (−X direction) in the width direction. Therefore, the covering portion 226 that has reached the first support edge 52a rotates more than 90 ° from the closed position Pc.

The covering portion 226 rotates so as to be separated from the first support edge 52a by its own weight and inertia. The end portion 246a of the sliding portion 246 of the guide 244 abuts on the upper surface 226b of the covering portion 226 and supports the covering portion 226. Thereby, the end portion 246a limits the further rotation of the covering portion 226.

The end portion 246a of the sliding portion 246 supports, for example, the covering portion 226 rotated by about 105 ° from the closed position Pc. As a result, the covering portion 226 located at the open position Po can be sufficiently separated from the member such as the sheet 12 and the conversion mechanism 63.

As described above, the guide end wall 53 pushes the cover portion 226 from the closed position Pc to the open position Po by moving the slider 22 so as to approach the cover portion 226. The end portion 246a of the sliding portion 246 supports the covering portion 226 so that the covering portion 226 is kept in the open position Po.

On the other hand, by moving the slider 22 in the Y direction, at least one of the plurality of covering portions 226 is moved from the open position Po to the closed position Pc. Hereinafter, the movement of the cover portion 226 from the open position Po to the closed position Pc will be described with a focus on one cover portion 226.

First, the slider 22 moves in the Y direction so as to move away from the cover portion 226 located at the open position Po. As a result, the covering portion 226 slides on the end portion 246a of the sliding portion 246 of the guide 244 and reaches the returning portion 247.

As the slider 22 moves further, the end portion 247a of the return portion 247 rotates the cover portion 226 toward the closed position Pc. In other words, the end portion 247a of the return portion 247 reduces the rotation angle of the cover portion 226 from the closed position Pc. The rotation angle of the covering portion 226 from the closed position Pc is the inclination angle of the covering portion 226 with respect to the outer surfaces 34a and 35a of the upper walls 34 and 35.

The return portion 247 rotates the cover portion 226 so that the rotation angle from the closed position Pc is smaller than 90 °. For example, the return portion 247 rotates the cover portion 226 until the rotation angle from the closed position Pc becomes 70 °.

The covering portion 226 rotates by its own weight and is supported by the guide side wall 52 or the guide end wall 53 of the guide member 27. The covering portion 226 approaches the closed position Pc from the open position Po by its own weight while being sequentially supported by the second support edge 52b of the guide side wall 52 and the support surface 53a of the guide end wall 53.

FIG. 21 is a cross-sectional view showing the slide rail device 11 of the fourth embodiment along the line F21-F21 of FIG. As shown in FIG. 21, the covering portion 226 may be separated from the opening 39 at the position (coordinates) where the first pressing portion 245 is provided in the Y direction. The first pressing portion 245 pushes the covering portion 226 separated from the opening 39 to the closed position Pc as the slider 22 moves.

The second pressing portion 250 is in a normal state so that the hook member 204 is in the deformed state Sd at the position (coordinates) where the first pressing portion 245 in the Y direction pushes the covering portion 226 with the movement of the slider 22. The hook member 204 of Sr is elastically deformed to the deformed state Sd. Therefore, when the first pressing portion 245 pushes the covering portion 226, the covering portion 226 comes into contact with the hook member 204 elastically deformed to the deformed state Sd.

Since the hook member 204 is elastically deformed to the deformed state Sd in advance, the covering portion 226 can get over the claw 204c of the hook member 204 by slightly elastically deforming the hook member 204. The covering portion 226 pressed by the first pressing portion 245 reaches the closed position Pc by overcoming the claw 204c.

When the cover portion 226 reaches the closed position Pc, the hook member 204 is restored, and the claw 204c is caught in the engagement groove 226d of the cover portion 226. As a result, the holding portion 230 holds the covering portion 226 at the closed position Pc.

As described above, the first pressing portion 245 closes the covering portion 226 separated from the opening 39 so that the hook member 204 is caught in the engaging groove 226d with elastic deformation as the slider 22 moves. Press to Pc. In other words, the covering portion 226 elastically deforms the hook member 204 by being pushed from the first pressing portion 245, and gets over the claw 204c of the hook member 204.

The claw 204c of the hook member 204 elastically deformed by the second pressing portion 250 may be separated from the covering portion 226 pressed by the first pressing portion 245. In this case, the covering portion 226 can smoothly move to the closed position Pc while avoiding the claw 204c.

As described above, since the second pressing portion 250 elastically deforms the hook member 204 to the deformed state Sd in advance, it is possible to suppress the generation of noise due to the sudden elastic deformation of the hook member 204. The second pressing portion 250 may be omitted, and the covering portion 226 may push the hook member 204 so as to be elastically deformed between the normal state Sr and the deformed state Sd.

When the cover portion 226 reaches the closed position Pc, the slider 22 is separated from the cover portion 226. By moving the slider 22 away from the cover portion 226 in this way, the cover portion 226 moves from the open position Po to the closed position Pc.

As described above, the end portion 246a of the sliding portion 246, the end portion 247a of the return portion 247, and the first pressing portion 245 are made of the cushion material. Therefore, the end portions 246a, 247a and the first pressing portion 245 can suppress the generation of noise when they come into contact with the covering portion 226.

FIG. 22 is a cross-sectional view showing a slide rail device 11 in which an external force F acts on the mounting portion 225 of the fourth embodiment. As shown in FIG. 22, when the covering portion 226 is located at the closed position Pc, for example, when the mounting portion 225 is stepped on by the passenger of the vehicle 1, an external force F in the −Z direction acts on the mounting portion 225. There is. The -Z direction is also referred to as a third direction. Further, the −Z direction is a direction from the covering portion 226 located at the closed position Pc toward the upper walls 34 and 35 of the lower rail 25.

When the external force F acts on the mounting portion 225, the elastic member 229 between the covering portion 226 and the upper walls 34 and 35 is compressed. As a result, the covering portion 226 is displaced in the −Z direction so as to approach the upper walls 34 and 35. Further, the contact surface 225a of the mounting portion 225 is displaced in the −Z direction so as to approach the receiving surface 216a of the receiving portion 216.

When the mounting portion 225 is displaced in the −Z direction due to the external force F and the contact surface 225a abuts on the receiving surface 216a, the receiving portion 216 supports the mounting portion 225. The receiving portion 216 restricts the mounting portion 225 from being further displaced in the −Z direction.

The upper portion 205a of the mounting shaft 205 is separated from the mounting portion 225 on which the external force F acts in the −Z direction when the covering portion 226 is located at the closed position Pc. For example, when the receiving portion 216 supports the mounting portion 225, a space Dc is provided between the upper portion 205a and the bottom surface 227b of the insertion hole 227 of the mounting portion 225. In other words, the upper portion 205a is separated from the bottom surface 227b of the insertion hole 227 of the mounting portion 225 on which an external force acts in the −Z direction when the covering portion 226 is located at the closed position Pc in the −Z direction.

The mounting portion 225 on which the external force F acts pushes the receiving portion 216 in the −Z direction. On the other hand, the bottom surface 227b of the mounting portion 225 on which the external force F acts is separated from the mounting shaft 205 and does not push the mounting shaft 205 in the −Z direction. As a result, deformation of the mounting shaft 205 is suppressed. The inner surface of the mounting portion 225 in contact with the mounting shaft 205 may push the mounting shaft 205 in the −Z direction by, for example, a frictional force.

When the mounting shaft 205 is deformed so as to bend in the −Z direction, the mounting portion 225 is also displaced in the −Z direction. In this case, the covering portion 226 may be pushed by the upper wall 34, and the covering portion 226 may float from the upper wall 35. However, in the present embodiment, since the deformation of the mounting shaft 205 is suppressed, the covering portion 226 is suppressed from floating from the upper wall 35.

For example, the cover 220 may be deformed by a strong external force F so that the upper portion 205a of the mounting shaft 205 may come into contact with the bottom surface 227b of the insertion hole 227. However, the contact surface 225a of the mounting portion 225 comes into contact with the receiving surface 216a of the receiving portion 216 before the upper portion 205a contacts the bottom surface 227b.

The receiving portion 216 may support the mounting portion 225 on which a force acting in another direction acts. For example, when the covering portion 226 is located at the closed position Pc, the mounting portion 225 may be kicked by the occupant of the vehicle 1 and an external force in the X direction may act on the mounting portion 225. The receiving portion 216 may support the mounting portion 225 on which the external force acts.

In the slide rail device 11 of the fourth embodiment described above, the slider 22 has a first pressing portion 245 that pushes the covering portion 226 separated from the opening 39 to the closing position Pc. As a result, even if the holding portion 84 is provided, the covering portion 226 that can move between the open position Po and the closing position Pc can surely move to the closing position Pc and cover the opening 39.

The slider 22 pushes the covering portion 226 separated from the opening 39 to the closed position Pc so that one of the hook member 204 and the engaging groove 226d is caught by the other with elastic deformation as the slider 22 moves. , Has a first pressing portion 245. As a result, the cover portion 226 accompanied by elastic deformation of the hook member 204 or the engaging groove 226d when moving from the open position Po to the closed position Pc can be reliably moved to the closed position Pc. Further, since the first pressing portion 245 pushes the covering portion 226 by using the movement of the slider 22, the slide rail device 11 does not require a complicated configuration for moving the covering portion 226 to the closed position Pc.

The hook member 204 can be elastically deformed between the normal state Sr and the deformed state Sd. The hook member 204 in the normal state Sr can be caught in the engaging groove 226d when the covering portion 226 is located at the closed position Pc. The hook member 204 in the deformed state Sd is separated from the engaging groove 226d than the normal state Sr when the covering portion 226 is located at the closed position Pc. The slider 22 has a second pressing portion 250. The second pressing portion 250 is a hook in the normal state Sr so that the hook member 204 is in the deformed state Sd at the position where the first pressing portion 245 in the Y direction pushes the covering portion 226 with the movement of the slider 22. The member 204 is elastically deformed to the deformed state Sd. That is, the second pressing portion 250 elastically deforms the hook member 204 so as to avoid the covering portion 226 pressed by the first pressing portion 245. This eliminates the need for the cover portion 226 to significantly elastically deform the hook member 204, and the hook member 204 can suppress the generation of noise due to the elastic deformation.

The rail 21 supports a mounting shaft 205 to which the mounting portion 225 is mounted and a receiving portion 216 on which an external force F in a predetermined direction (-Z direction) acts when the covering portion 226 is located at the closed position Pc. And have. When the receiving portion 216 supports the mounting portion 225 and the external force F in the −Z direction acts on the mounting portion 225 when the covering portion 226 is located at the closed position Pc, the mounting portion 225 acts on the mounting shaft 205. The power to do is reduced. Therefore, the deformation and displacement of the mounting shaft 205 is suppressed by the transmission of the external force F from the mounting portion 225, and the cover portion 226 moves from the closed position Pc to the open position Po due to the deformation and displacement of the mounting shaft 205. Deformation and displacement of the cover 220 are suppressed.

The mounting shaft 205 is a shaft extending in the Y direction. The mounting portion 225 is mounted on the mounting shaft 205 so that the covering portion 226 can rotate around the mounting shaft 205 between the closed position Pc and the open position Po. The −Z direction is the direction from the covering portion 226 located at the closed position Pc toward the upper walls 34 and 35. For example, when the mounting portion 225 is stepped on, an external force F in the −Z direction acts on the mounting portion 225. In this case, since the receiving portion 216 supports the mounting portion 225, the mounting shaft 205 is suppressed from being deformed by the transmission of the external force F from the mounting portion 225, and the cover portion 226 is closed at the closed position Pc due to the deformation of the mounting shaft 205. The rotation of the cover 220 that moves from the to the open position Po is suppressed.

The receiving portion 216 is arranged at a position separated from the mounting portion 225. However, when the mounting portion 225 is displaced in the −Z direction due to the external force F, the receiving portion 216 supports the mounting portion 225. As a result, the receiving portion 216 is prevented from interfering with the mounting portion 225 that has not received the external force F in the −Z direction. Therefore, for example, the receiving portion 216 can suppress the movement of the covering portion 226 between the closed position Pc and the open position Po accompanied by the movement or rotation of the mounting portion 225.

The upper portion 205a of the mounting shaft 205 facing in the + Z direction is separated from the mounting portion 225 on which the external force F acts in the −Z direction when the covering portion 226 is located at the closed position Pc. Therefore, the mounting shaft 205 can suppress the transmission of the external force F from the mounting portion 225 in the −Z direction. Therefore, the deformation and displacement of the mounting shaft 205 is suppressed by the transmission of the external force F from the mounting portion 225, and the cover portion 226 moves from the closed position Pc to the open position Po due to the deformation and displacement of the mounting shaft 205. Deformation and displacement of the cover 220 are suppressed.

The upper portion 205a of the mounting shaft 205 facing in the + Z direction is separated from the mounting portion 225 on which the external force F acts in the −Z direction when the covering portion 226 is located at the closed position Pc. Therefore, the mounting shaft 205 can suppress the transmission of the external force F from the mounting portion 225 in the −Z direction. Therefore, the deformation of the mounting shaft 205 is suppressed by the transmission of the external force F from the mounting portion 225, and the rotation of the cover 220 such that the covering portion 226 moves from the closed position Pc to the open position Po due to the deformation of the mounting shaft 205. Is suppressed. Further, the mounting portion 225 is provided with an insertion hole 227 through which the mounting shaft 205 passes. When the covering portion 226 is located at the closed position Pc, the length of the insertion hole 227 in the −Z direction is longer than the length of the insertion hole 227 in the + X direction. As a result, even if the receiving portion 216 is separated from the mounting portion 225 in the −Z direction, the mounting portion 225 on which the external force F acts in the −Z direction is displaced in the −Z direction until it is supported by the receiving portion 216. In the meantime, contact with the mounting shaft 205 is suppressed.

The end portion 227a of the insertion hole 227 in the −Z direction when the covering portion 226 is located at the closed position Pc is opened to the outside of the mounting portion 225. The length of the end portion 227a of the insertion hole 227 in the X direction when the covering portion 226 is located at the closed position Pc is shorter than the diameter of the mounting shaft 205. Further, the mounting shaft 205 passing through the insertion hole 227 restricts the mounting portion 225 from moving in the X direction when the covering portion 226 is located at the closed position Pc. As a result, the mounting shaft 205 can be attached to and detached from the insertion hole 227 by snap-fitting through the end portion 227a of the insertion hole 227.

The plurality of covers 220 are movable in the closed position Pc covering the opening 39 and the open position Po separated from the opening 39, and are arranged in the Y direction. The plurality of covers 220 include a first cover 221 and a second cover 222. The second cover 222 located at the closed position Pc covers the support portion 221b that covers the opening 39 of the first cover 221 located at the closed position Pc. As a result, the plurality of covers 220 can suppress the formation of a gap that exposes the opening 39 between the first cover 221 and the second cover 222, and thus the first cover 221 and the second cover 222. It is possible to prevent foreign matter from entering the opening 39 through the gap between the two.

One of the first cover 221 and the second cover 222 has a protrusion 228 protruding from the one mounting portion 225 toward the other mounting portion 225 of the first cover 221 and the second cover 222. Have. As a result, the main portion 221a of the cover portion 226 of the first cover 221 designed not to be covered by the second cover 222 is separated from the cover portion 226 of the second cover 222 in the Y direction. Therefore, it is possible to prevent the second cover 222 from covering an undesired portion of the first cover 221. Further, even if the protruding portion 228 is provided, the second cover 222 located at the closed position Pc covers the support portion 221b covering the opening 39 of the first cover 221 located at the closed position Pc. It is suppressed that a gap for exposing the opening 39 is formed between the cover 221 and the second cover 222.

The first cover 221 has a protrusion 228. The cover portion 226 of the first cover 221 has a main portion 221a that covers the opening 39 at the closed position Pc, and a support portion 221b that protrudes from the main portion 221a toward the cover portion 226 of the second cover 222. The support portion 221b of the first cover 221 located at the closed position Pc covers the opening 39 and is covered with the extended portion 222b of the second cover 222 located at the closed position Pc. That is, the protruding portion 228 and the supporting portion 221b project from the first cover 221 toward the second cover 222 in substantially the same direction. As a result, the main portion 221a of the covering portion 226 of the first cover 221 is separated from the covering portion 226 of the second cover 222 in the Y direction. Therefore, it is possible to prevent the second cover 222 from covering the main portion 221a of the first cover 221. Further, even if the projecting portion 228 is provided, the second cover 222 located at the closed position Pc covers the support portion 221b of the first cover 221 located at the closed position Pc, so that the first cover 221 and the second cover 221 and the second cover 221 are provided. It is suppressed that a gap for exposing the opening 39 is formed between the cover 222 and the cover 222.

The first cover 221 has a lower surface 226a facing the rail 21 when located at the closed position Pc, an upper surface 226b opposite the lower surface 226a, and a support surface 226e closer to the lower surface 226a than the upper surface 226b. The second cover 222 faces the lower surface 226a facing the rail 21 when located at the closed position Pc, the upper surface 226b opposite the lower surface 226a, and faces the rail 21 when located at the closed position Pc and is more than the lower surface 226a. It has a concave surface 226f close to the upper surface 226b. The support surface 226e and the concave surface 226f face each other when the first cover 221 and the second cover 222 are located at the closed position Pc.
