Description

  Embodiments described herein relate generally to a vehicle slide rail device.

  2. Description of the Related Art Conventionally, a vehicular slide rail device including a lower rail provided on a vehicle floor, an upper rail fixed to a seat and movably attached to the lower rail, and a member attached to the lower rail is known. The member is attached to the lower rail, for example, to aid in the drainage of foreign material such as a lighter.

  The member has, for example, a protrusion which is passed through the through hole of the lower rail. When the projection is passed through the through hole, the claw provided at the lower end of the projection comes into contact with the lower surface of the lower rail, and the member is attached to the lower rail (Patent Document 1).

JP 2017-035911 A

  However, in the conventional configuration, when the protruding portion is inserted into the through hole, the lower end of the protruding portion may come off the through hole and collide with the lower rail. Since the claw part located at the lower end is provided so as to be elastically deformable so as to avoid the edge of the through hole, the protruding part may be damaged by a collision. In this case, the members are replaced, which increases the cost of the slide rail device.

  Then, this invention is made in view of the above, and provides the slide rail apparatus for vehicles which can suppress the damage of the member at the time of attachment.

  As an example, a vehicle slide rail device according to an embodiment of the present invention is provided with a lower rail having a hole and a bottom wall extending in a first direction, and attached to the lower rail so as to be movable in the first direction. An upper rail, a member having a first surface facing the bottom wall, a protrusion configured to protrude from the first surface and pass through the hole, and a position spaced from the first surface A base portion provided in the projecting portion, and at least one claw extending from the base portion in a direction approaching the first surface and elastically deforming so as to approach the projecting portion, and elastically deforming the nail And the bottom wall is disposed between the claw and the first surface so as to attach the member to the bottom wall. 1 mounting portionFor example, when the first attachment portion is inserted into the hole, the first attachment portion may come into contact with the bottom wall. Since the nail extends from the base in a direction approaching the first surface, the base is more likely to come into contact with the bottom wall than the nail. The base is less likely to deform than the elastically deformable nail. For this reason, it is suppressed that a 1st attachment part is damaged at the time of contact | abutting with a 1st attachment part and a bottom wall. That is, the damage of the member at the time of attachment is suppressed.

  As an example, the vehicle slide rail device is provided in the member at a position spaced from the first attachment portion in the first direction, and is configured to attach the member to the bottom wall. The apparatus further comprises: Thus, as one example, the member is attached to the bottom wall by the first attachment portion and the second attachment portion at a plurality of positions separated in the first direction, so that the member is attached to the bottom wall more reliably.

  In the slide rail apparatus for a vehicle, as an example, the length of the protrusion in the first direction intersects the first direction and the length of the protrusion in a second direction along the first surface. Longer than length. When the member is attached to the bottom wall of the lower rail, the member is not completely horizontal with respect to the bottom wall, and is inclined on a virtual plane including a first direction and a direction perpendicular to the first surface. Sometimes. At this time, the first mounting portion inserted into the hole may come into contact with the bottom wall, and the force on the virtual plane may act on the protruding portion. However, since the length of the protrusion in the first direction is long, the strength of the protrusion with respect to the force is improved, and damage to the first attachment portion is suppressed.

  In the slide rail apparatus for a vehicle, as an example, the first mounting portion has at least three claws extending radially from the base and in a direction approaching the first surface. Thus, as an example, when the first attachment portion is inserted into the hole, a portion near the proximal end of one claw extending in at least one of the directions can abut the bottom wall. The portion near the proximal end of the nail is less likely to deform than the portion near the tip of the nail. For this reason, damage to the first mounting portion is suppressed.

  In the slide rail apparatus for a vehicle, as an example, the member is a second surface located on the opposite side of the first surface, and a protruding wall which protrudes from the second surface and extends in the first direction. And. Therefore, as an example, the protruding wall can support, for example, a foreign matter that has entered the lower rail in an upright or inclined state, and the upper rail can help push the foreign matter out of the lower rail. Therefore, the entry of foreign matter between the upper rail and the lower rail is suppressed.

  In the above slide rail apparatus for a vehicle, as one example, the bottom wall includes a third surface facing the first surface, a fourth surface opposite to the third surface, and the hole. An inner circumferential surface to be formed, and the claw has a first locking surface facing the fourth surface and a second locking surface facing the inner circumferential surface. Thus, as one example, while the first attachment portion is prevented from being pulled out of the hole, the movement of the member relative to the bottom wall in the direction along the first surface is suppressed. It is suppressed that backlash with the bottom wall occurs.

  The upper wall 41 is a plate-like portion that extends on the XY plane, and extends in the direction along the Y axis. The upper wall 41 is located outside the lower rail 21. In the cross section of FIG. 3, the two insertion walls 42 extend in the negative direction along the Z axis from both ends of the upper wall 41 in the direction along the X axis. The negative direction along the Z axis is the opposite direction of the arrow of the Z axis, and is the downward direction in the present embodiment.

  The two insertion walls 42 are passed through the gap between the two inner walls 34 of the lower rail 21. The curved wall 43 is located inside the lower rail 21. The curved wall 43 is bent so as to extend from the lower end of the insertion wall 42 toward the connecting wall 33 of the lower rail 21.

  As shown in FIG. 2, the insertion wall 42 is provided with a plurality of locking grooves 46. The locking groove 46 is a notch that opens at the lower end of the insertion wall 42 and extends upward. The plurality of locking grooves 46 are provided at substantially equal intervals in the direction along the Y axis. The interval between the plurality of locking grooves 46 is substantially equal to the interval between the lock grooves 36 of the lower rail 21.

  The cap 23 is made of, for example, a synthetic resin. The cap 23 is attached to the end portion of the upper rail 22 in the rear direction, and closes the end of the upper rail 22 in the rear direction.

  The lock mechanism 24 has a handle 51, a release lever 52, and a spring 53. The lock mechanism 24 restricts (locks) the sliding movement of the upper rail 22 with respect to the lower rail 21. By operating the handle 51, the lock mechanism 24 releases the lock so that the upper rail 22 can slide relative to the lower rail 21.

As shown in FIGS. 6 and 7, the first attachment portion 72 includes a protruding portion 81, a base portion 82, and four claws 83. Base 82 may also be referred to as the bottom.

  The protruding portion 81 protrudes downward from the lower surface 71 a of the plate portion 71. The protruding portion 81 may not be continuous with the lower surface 71a but may be separated from the lower surface 71a. For example, the protruding portion 81 may pass through the through hole provided in the plate portion 71 from the upper side to the lower side, and may be separated from the edge of the through hole. Also in this case, the protrusion 81 protrudes downward from the lower surface 71 a. In other words, the protruding portion 81 protrudes downward from the lower surface 71a from the lower surface 71a or from a portion positioned above the lower surface 71a.

  The protrusion 81 is formed in a solid plate shape. By being formed solid, the strength of the protruding portion 81 is improved, and deformation of the protruding portion 81 is suppressed. When the lower surface 71a is viewed in a plan view as shown in FIG. 7, the protruding portion 81 extends in a direction along the Y axis. In other words, the length of the protrusion 81 in the direction along the Y axis is longer than the length (width) of the protrusion 81 in the direction along the X axis. The protrusion 81 is not limited to this example, and may be, for example, a cylindrical shape or may be hollow.

  As shown in FIG. 6, the base 82 is provided at the lower end of the protrusion 81.

As shown in FIGS. 5 and 8, the four claws 83 extend radially from the base portion 82 in a direction approaching the lower surface 71 a of the plate portion 71. Therefore, the claw 83 separates from the protrusion 81 as it goes to the lower surface 71a.

  The four claws 83 are spaced apart from each other in the direction of rotation around the central axis Ax of the protrusion 81. In the direction along the X axis, two claws 83 protrude from the base 82 toward the positive direction side along the X axis. Furthermore, in the direction along the X axis, two claws 83 protrude from the base 82 toward the negative direction along the X axis.

  The distance between the two claws 83 projecting in the positive direction along the X axis is substantially equal to the distance between the two claws 83 projecting in the negative direction along the X axis. On the other hand, the distance between the claw 83 protruding in the positive direction side along the X axis and the claw 83 protruding in the negative direction side along the X axis is the distance between the claw 83 protruding in the positive direction or the negative direction side along the X axis. The distance between the two claws 83 is longer. The four claws 83 may be arranged at equal intervals.

  As shown in FIG. 8, the claw 83 has a connection end 83 a and a free end 83 b. The connection end 83 a is the lower end of the claw 83 and is connected to the base 82. The free end 83 b is the upper end of the claw 83 and is separated from the protrusion 81. For this reason, the nail | claw 83 can be elastically deformed in the direction which approaches the protrusion part 81 by using the connection edge part 83a as a fulcrum.

  The claw 83 further has a first locking surface 83c and a second locking surface 83d. The first locking surface 83c may also be referred to as a first contact portion. The first locking surface 83c is a substantially flat surface facing upward at a position separated from the lower surface 71a of the plate portion 71 in the direction along the Z-axis. The second locking surface 83d is a substantially arc-shaped curved surface that faces away from the central axis Ax.

  As shown in FIG. 6, the second attachment portion 73 has a protrusion 85 and a claw 86. The protruding portion 85 protrudes downward from the lower surface 71 a of the plate portion 71. The claw 86 projects forward from the projecting portion 85 at a position spaced downward from the lower surface 71 a of the plate portion 71.

  The claw 86 has a locking surface 86a. The locking surface 86a can also be referred to as a second contact portion. The locking surface 86a is a substantially flat surface facing upward in a position spaced from the lower surface 71a of the plate portion 71 in the direction along the Z axis.

  In the direction along the Z axis, the distance C1 between the first locking surface 83c of the first mounting portion 72 and the lower surface 71a of the plate portion 71 is the locking surface 86a and the lower surface 71a of the second mounting portion 73. Longer than the distance C2.

On the other hand, the first projecting wall 74 is provided at the object inclined portion 92. The first projecting wall 74 is located outside the opening forming portion 91 in the direction along the Y axis.

  The first protruding wall 74 has a first end 74a and a second end 74b in the direction along the Y axis. The first end 74a is an end of the first protruding wall 74 in the negative direction (rear direction) along the Y axis. The second end 74 b is opposite to the first end 74 a and is an end of the first projecting wall 74 in the positive direction (forward direction) along the Y-axis.

  The second end 74 b is closer to the opening formation portion 91 than the first end 74 a. In the present embodiment, the second end 74 b is located at the end of the object inclined portion 92 in the positive direction along the Y axis and is adjacent to the opening forming portion 91.

  For example, when viewed from the direction along the X axis as shown in FIG. 6, the first end 74a of the first projecting wall 74 and the second end in the direction along the Y axis of the first foreign object interference member 25 A portion located between the end 74 b is the object inclined portion 92. According to another expression, in the direction along the Y axis, the portion of the first foreign object interference member 25 which is located rearward of the second end 74 b is the object inclined portion 92.

  When viewed from the direction along the X-axis, the portion of the first foreign object interference member 25 outside the object inclined portion 92 is the opening forming portion 91. In other words, in the direction along the Y-axis, the portion of the first foreign object interference member 25 located in the forward direction of the second end 74 b is the opening forming portion 91. In the present embodiment, the length of the opening forming portion 91 in the direction along the Y axis is shorter than the length of the object inclined portion 92.

  The first opening 78 is provided at the end of the opening forming portion 91 in the rear direction, and is adjacent to the object inclined portion 92. The end of the first projecting wall 74 in the front direction is adjacent to the first opening 78. Thus, the first projecting wall 74 extends from the first end 71 c of the plate 71 to the first opening 78.

  In the present embodiment, the first attachment portion 72 is provided on the object inclined portion 92, and the second attachment portion 73 is provided on the opening forming portion 91. The protrusion 81 of the first attachment portion 72 is continuous with the first protrusion wall 74. The length (width) of the protrusion 81 in the direction along the X axis is substantially equal to the length (width) of the first protruding wall 74 in the direction along the X axis.

  As shown in FIG. 4, the two second protruding walls 75 and the two third protruding walls 76 extend in the direction along the Y axis across the opening forming portion 91 and the object inclined portion 92. That is, the second projecting wall 75 and the third projecting wall 76 are provided in the opening forming portion 91 and provided in the object inclined portion 92.

  The third projecting wall 76 extends from one end (first end 71c) to the other end (second end 71d) of the upper surface 71b in the direction along the Y-axis. In the direction along the Y-axis, the length of the first projecting wall 74 is shorter than the length of the second projecting wall 75 and shorter than the length of the third projecting wall 76.

  As shown in FIG. 7, the two protrusions 77 protrude downward from both ends of the lower surface 71a of the plate portion 71 in the direction along the X axis, and are separated from each other in the direction along the X axis. In other words, the two protrusions 77 protrude from the third end portion 71e and the fourth end portion 71f. Therefore, the first projecting wall 74 and the two second projecting walls 75 project from the upper surface 71b at positions different from the two protrusions 77 in the direction along the X axis.

  The plate portion 71 further has a continuous region 95. The continuous region 95 is a region in which the lower surface 71a continues in the direction along the X axis between the third end portion 71e and the fourth end portion 71f. The continuous region 95 extends linearly in the direction along the X axis and is substantially flat. In FIG. 7, the continuous area 95 is schematically shown surrounded by a two-dot chain line.

  The two protrusions 77 protrude from the continuous region 95. In other words, the two protrusions 77 are arranged on the lower surface 71a at a position different from the discontinuous area, avoiding a discontinuous area in the direction along the X axis.

  The protrusion 77 is located between the first attachment portion 72 and the second attachment portion 73 in the direction along the Y axis. The two protrusions 77 are disposed at overlapping positions in the direction along the Y axis. According to another expression, the two protrusions 77 are arranged at positions overlapping each other when viewed from the direction along the X axis.

  In the direction along the Y axis, the distance between the protrusion 77 and the first attachment portion 72 is shorter than the distance between the protrusion 77 and the second attachment portion 73. The positions of the two protrusions 77 are not limited to the positions described above, and may be at other positions. For example, the two protrusions 77 may be arranged at different positions in the direction along the Y axis.

  In the direction along the X axis, the length (width) of the protrusion 77 is shorter than the length (width) of the plate portion 71. The length of the projection 77 is shorter than the length of the plate portion 71 in the direction along the Y axis. In the direction along the Z-axis, the length (thickness) of the protrusion 77 is shorter than the length (thickness) of the plate portion 71. In other words, in the direction along the Z-axis, the length between the lower surface 71a and the tip of the protrusion 77 is shorter than the length between the lower surface 71a and the upper surface 71b of the plate portion 71. The length of the protrusion 77 is not limited to this example.

  The first foreign matter interference member 25 is attached to the lower rail 21 as described below, for example. In addition, the attachment method of the 1st foreign material interference member 25 is not limited to the following procedures and work.

  As shown in FIG. 6, a first mounting hole 101, a second mounting hole 102, a first insertion hole 103, and a second insertion hole 104 are provided in the bottom wall 31 of the lower rail 21. The first mounting holes 101 may also be referred to as first holes or holes. The second mounting hole 102 may also be referred to as a second hole. Furthermore, the bottom wall 31 has a first inner circumferential surface 101 a forming the first mounting hole 101 and a second inner circumferential surface 102 a forming the second mounting hole 102.

  The first mounting hole 101, the second mounting hole 102, the first insertion hole 103, and the second insertion hole 104 each penetrate the bottom wall 31 in the direction along the Z axis, and the bottom surface 31a of the bottom wall 31. And a hole having a circular cross section that opens in the inner surface 31b. The first attachment hole 101, the second attachment hole 102, the first insertion hole 103, and the second insertion hole 104 may have other shapes.

  The second mounting hole 102 is provided at a position separated from the first mounting hole 101 in the direction along the Y axis. The first insertion hole 103 and the second insertion hole 104 are located between the first attachment hole 101 and the second attachment hole 102 in the direction along the Y axis.

  FIG. 9 is a perspective view showing the first foreign matter interference member 25 according to the first embodiment and a part of the lower rail 21 on which the second attachment portion 73 is hooked. As shown in FIG. 9, first, the second attachment portion 73 is inserted into the second attachment hole 102 with the lower surface 71 a of the plate portion 71 facing the inner surface 31 b of the bottom wall 31. The second mounting hole 102 has a size through which the second mounting portion 73 can pass.

  As shown in FIG. 6, when the second attachment portion 73 is inserted into the second attachment hole 102, the protruding portion 85 of the second attachment portion 73 is passed through the second attachment hole 102. The contact of the protrusion 85 with the second inner circumferential surface 102 a of the second attachment hole 102 restricts the movement of the first foreign object interference member 25 in the forward direction.

  The claw 86 is disposed below the bottom wall 31, and the locking surface 86 a faces the bottom surface 31 a of the bottom wall 31. In other words, the claws 86 are hooked on the bottom wall 31. For this reason, the bottom wall 31 is disposed between the lower surface 71a of the plate portion 71 and the locking surface 86a, and the movement of the first foreign object interference member 25 in the direction along the Z axis is limited.

  FIG. 10 is a perspective view showing the first foreign matter interference member 25 of the first embodiment and a part of the lower rail 21 to which the first attachment portion 72 is fitted. Next, as shown in FIG. 10, the first attachment portion 72 is inserted into the first attachment hole 101 in a state where the second attachment portion 73 is hooked on the bottom wall 31.

  For example, the first attachment portion 72 is rotated by moving the plate portion 71 so as to approach the bottom wall 31 with the contact portion between the second attachment portion 73 and the second inner circumferential surface 102a as the approximate center. Approaches one mounting hole 101. Further, the protrusion 77 contacts the bottom wall 31. When the projection 77 abuts on the bottom wall 31, the first locking surface 83c of the first mounting portion 72 is positioned above the bottom surface 31a. In this case, the first foreign matter interference member 25 is not attached to the bottom wall 31 and can be removed from the bottom wall 31.

  Next, as shown in FIG. 6, the plate portion 71 is elastically deformed so that the first end portion 71 c is brought close to the bottom wall 31. By elastically deforming the plate portion 71, the first attachment portion 72 is inserted into the first attachment hole 101 with the elastic deformation of the plurality of claws 83. That is, the first mounting hole 101 has a size that allows the first mounting portion 72 to pass through by elastically deforming the plurality of claws 83 so as to approach the protruding portion 81. In a state in which the plurality of claws 83 are not elastically deformed so as to approach the protrusion 81, the maximum outer diameter of the first attachment portion 72 is larger than the maximum outer diameter of the first attachment hole 101.

  When the first mounting portion 72 is inserted into the first mounting hole 101, the protruding portion 81 of the first mounting portion 72 is passed through the first mounting hole 101, and the elastically deformed claw 83 is restored. The base 82 and a part of the claw 83 are disposed below the bottom surface 31 a.

  As shown in FIG. 8, the first locking surface 83 c of the restored claw 83 faces the bottom surface 31 a of the bottom wall 31. In other words, the claws 83 are hooked on the bottom wall 31. Therefore, the bottom wall 31 is disposed between the lower surface 71a of the plate portion 71 and the first locking surface 83c of the claw 83, and the first foreign matter interference member 25 is restricted from moving in the direction along the Z axis. Be done. Thereby, the first foreign object interference member 25 is attached to the bottom wall 31.

  Further, the second locking surfaces 83 d of the plurality of claws 83 face the first inner peripheral surface 101 a of the bottom wall 31. This restricts the movement of the first foreign substance interference member 25 in the direction along the inner surface 31 b of the bottom wall 31.

  For example, the claw 83 may be maintained in an elastically deformed state, and the second locking surface 83 d may be pressed against the first inner circumferential surface 101 a by the restoring force of the claw 83. Thereby, the first foreign object interference member 25 is fixed to the bottom wall 31 more strongly.

  As shown in FIG. 6, the projection 77 keeps the plate portion 71 in an elastically deformed state by contacting the inner surface 31 b of the bottom wall 31. The plate portion 71 elastically deformed with the contact portion between the projection 77 and the bottom wall 31 as a fulcrum presses the first locking surface 83c of the first mounting portion 72 against the bottom surface 31a of the bottom wall 31 by a restoring force, The locking surface 86a of the second mounting portion 73 is pressed against the bottom surface 31a. Thereby, the first foreign object interference member 25 is fixed to the bottom wall 31 more strongly.

  In the direction along the Z axis, the length L of the protrusion 77 is the length of the bottom wall 31 from the distance C1 between the lower surface 71a of the plate portion 71 and the first locking surface 83c of the first mounting portion 72. (Thickness) is equal to or longer than the length obtained by subtracting T (LCC1-T). Further, in the direction along the Z-axis, the length L of the protrusion 77 is the length (thickness) T of the bottom wall 31 from the distance C2 between the lower surface 71a and the locking surface 86a of the second mounting portion 73. Is equal to or longer than the length obtained by subtracting (L ≧ C2-T). As a result, the plate portion 71 is elastically deformed as described above, and the first locking surface 83 c and the locking surface 86 a are pressed against the bottom surface 31 a of the bottom wall 31. The length L of the protrusion 77 is not limited to this example.

  For example, a part of the lower surface 71 a contacts the inner surface 31 b of the bottom wall 31 at the first end portion 71 c and the second end portion 71 d. Thus, the continuous region 95 is a region in which the lower surface 71a which is the surface closest to the bottom wall 31 of the lower rail 21 extends in the direction along the X axis. The lower surface 71 a may be separated from the bottom wall 31 if the first mounting portion 72, the second mounting portion 73, and the projection 77 come in contact with the bottom wall 31.

  When the first foreign matter interference member 25 is attached to the bottom wall 31, the first opening 78 of the plate portion 71 and the first insertion hole 103 of the bottom wall 31 overlap and communicate with each other. Therefore, a member such as the rivet 105 can pass through the first opening 78 and the first insertion hole 103 from above. The rivet 105 is, for example, a pop rivet for attaching the bottom wall 31 and the first foreign object interference member 25 to the floor 1a of FIG.

  The second opening 79 and the second insertion hole 104 overlap and communicate with each other. Therefore, a member such as the reference pin 106 can pass from the lower direction to the second opening 79 and the second insertion hole 104. For example, the reference pin 106 positions the first foreign matter interference member 25 when measuring the dimensions of the first foreign matter interference member 25 and the lower rail 21 or when assembling the slide rail device 11. This facilitates the assembly of the slide rail device 11. The first opening 78 and the second opening 79 are not limited to these examples.

  As shown in FIG. 3, foreign matter (objects) 120 </ b> A and 120 </ b> B may enter the lower rail 21 from the gap between the two inner walls 34. The foreign objects 120A and 120B shown in FIG. 3 are lighters dropped by the passenger of the vehicle 1, for example. The foreign substances 120A and 120B are not limited to this example.

  For example, the foreign matter 120A interferes with the first projecting wall 74. For this reason, the foreign matter 120 </ b> A is supported in a standing or inclined state by the first projecting wall 74. In the example of FIG. 3, the foreign matter 120 </ b> A is supported not only by the first protruding wall 74 but also by the second protruding wall 75 and the inner wall 34 of the lower rail 21.

  Further, the foreign matter 120 </ b> B interferes with the third protruding wall 76. The gap between the tip (upper end) of the third projecting wall 76 and the tip (lower end) of the inner wall 34 of the lower rail 21 is smaller than the thickness of the foreign substance 120 B which is a lighter. For this reason, the third protruding wall 76 restricts the foreign matter 120B from entering the gap between the third protruding wall 76 and the inner wall 34. The foreign matter 120B is supported in an inclined state by the third protruding wall 76 and the two inner side walls 34.

  The foreign substances 120A and 120B supported in a standing or inclined state are disposed at positions overlapping the upper rails 22 in the direction along the Z-axis. For this reason, the upper rail 22 can push the foreign matter 120A, 120B forward by being slid forward. By being pushed by the upper rail 22, the foreign matters 120 </ b> A and 120 </ b> B are discharged from the inside of the lower rail 21 to the outside.

  As described above, the first projecting wall 74, the second projecting wall 75, and the third projecting wall 76 extend in parallel to the direction along the Y axis and are separated from each other in the direction along the X axis. For this reason, it is suppressed that the foreign matter 120A, 120B pushed forward is caught on the first projecting wall 74, the second projecting wall 75, and the third projecting wall 76, and the foreign matter 120A, 120B is inside the lower rail 21. Is easily discharged from.

  FIG. 11 is a perspective view showing the second foreign matter interference member 26 of the first embodiment. FIG. 12 is a perspective view showing the second foreign matter interference member 26 of the first embodiment from a direction different from FIG. 11. The second foreign object interference member 26 is made of synthetic resin. The second foreign matter interference member 26 may be made of other materials.

  The second foreign matter interference member 26 also has a plate portion 71, a first attachment portion 72, a second attachment portion 73, a first projecting wall 74, and a projection 77. The plate portion 71, the first mounting portion 72, the second mounting portion 73, the first protruding wall 74, and the projection 77 of the second foreign matter interference member 26 are integrally formed. For example, a plurality of members May be formed.

  In the second foreign matter interference member 26, the first end 71c of the plate 71 is the end of the plate 71 in the forward direction. The second end 71 d is an end of the plate portion 71 in the rear direction.

  In the second foreign matter interference member 26, the first projecting wall 74 extends from the first end 71c to the second end 71d across the first opening 78 and the second opening 79. In other words, the first projecting wall 74 covers the first opening 78 and the second opening 79 from above. For this reason, the second foreign matter interference member 26 does not have the opening forming portion 91 of the first foreign matter interference member 25. The second foreign matter interference member 26 may have the opening forming portion 91.

  The first protruding wall 74 is provided with a first notch 74c and a second notch 74d. The first notch 74 c communicates with the first opening 78. The second notch 74 d communicates with the second opening 79. By providing the first notch 74c and the second notch 74d, the first projecting wall 74 is prevented from contacting the member inserted into the first opening 78 or the second opening 79. .

  In the direction along the Z-axis, the length (height) of the first protruding wall 74 of the second foreign matter interference member 26 is the length (height) of the first protruding wall 74 of the first foreign matter interference member 25. Longer than). Therefore, the first notch 74c and the second notch 74d can be easily provided in the first projecting wall 74.

  As shown in FIG. 12, the second foreign matter interference member 26 has one protrusion 77 unlike the first foreign matter interference member 25. The projections 77 of the second foreign object interference member 26 also project from the continuous area 95. The protrusions 77 extend in the direction along the X axis between the third end 71 e and the fourth end 71 f that are both ends of the lower surface 71 a in the direction along the X axis. In other words, the projections 77 extend so as to cross the plate 71.

  As shown in FIG. 11, the second foreign matter interference member 26 further includes a first inclined portion 111 and a second inclined portion 112. The first inclined portion 111 and the second inclined portion 112 project from the upper surface 71 b of the plate portion 71.

  The first inclined portion 111 is provided from the portion where the first opening 78 is provided to the second end 71 d of the plate portion 71. The first inclined portion 111 is inclined so as to be separated from the upper surface 71 b as it goes backward.

  The second inclined portion 112 is located in the front direction with respect to the first opening 78 and is adjacent to the first opening 78. The second inclined portion 112 is inclined to be separated from the upper surface 71b as it goes backward.

  The second foreign matter interference member 26 is attached to the bottom wall 31 by the first attachment portion 72 and the second attachment portion 73 as in the case of the first foreign matter interference member 25. Then, the first projecting wall 74 supports a foreign object such as a lighter in a standing or inclined state. Therefore, by sliding the upper rail 22 in the backward direction, the upper rail 22 or the cap 23 pushes the foreign matter in the backward direction, and the foreign material is discharged from the inside of the lower rail 21 to the outside.

  The foreign material pushed by the upper rail 22 or the cap 23 rides on the first inclined portion 111 and the second inclined portion 112. Thereby, even if a member such as a rivet protrudes upward from the first opening 78, interference of foreign matter with the member is suppressed.

  In the slide rail device 11 according to the first embodiment described above, the protrusion 77 is located between the first mounting portion 72 and the second mounting portion 73 in the direction along the Y axis, and the bottom wall 31 The plate portion 71 is elastically deformed such that the first attachment portion 72 and the second attachment portion 73 are pressed against the bottom wall 31 by being in contact with the lower portion 31. Thereby, the first foreign matter interference member 25 is opposed to the bottom wall 31 while the gap between the bottom wall 31 used for elastic deformation of the first foreign matter interference member 25 and the first foreign matter interference member 25 is provided. Movement is suppressed. Therefore, the occurrence of rattling between the first foreign object interference member 25 and the bottom wall 31 is suppressed.

  The projections 77 project from the continuous area 95. The continuous region 95 is a region in which the lower surface 71a is continuous in the direction along the X-axis between the third end 71e and the fourth end 71f, and is less likely to be elastically deformed than a discontinuous region. For example, the upper rail 22 or the lock mechanism 24 may abut on the plate portion 71 or the first projecting wall 74, and the plate portion 71 may be pressed downward. In this case, since the plate portion 71 is unlikely to be deformed around the protrusion 77, the contact position between the protrusion 77 and the bottom surface 31a of the lower rail 21 is prevented from being changed. Therefore, even when the plate portion 71 is pushed, the projection 77 can be kept in contact with the bottom wall 31 of the lower rail 21 at a desired position. Stabilization of the position where the projection 77 abuts on the bottom wall 31 suppresses the occurrence of rattling between the first foreign object interference member 25 and the bottom wall 31.

  Two projections 77 project from the third end 71 e and the fourth end 71 f. Thus, the two protrusions 77 can abut on the bottom wall 31 stably. Further, the plate portion 71 is stably supported by the two protrusions 77, and the increase in weight of the first foreign object interference member 25 due to the provision of the protrusions 77 is suppressed.

  The two protrusions 77 are disposed at an overlapping position when viewed from the direction along the X axis in the direction along the Y axis. Thereby, in a state where the projection 77 abuts on the bottom wall 31, the plate portion 71 is suppressed from being elastically deformed so as to be twisted. Therefore, for example, a part of the first attachment portion 72 or the second attachment portion 73 may be separated from the bottom wall 31 undesirably, or the position where the projection 77 abuts on the bottom wall 31 may be shifted. The occurrence of rattling between the foreign object interference member 25 and the bottom wall 31 is suppressed. Further, the gap between the third projecting wall 76 and the inner wall 34 is undesirably changed, and the entry of the foreign matter 120A, 120B into the gap is suppressed.

  The first foreign matter interference member 25 has a first protruding wall 74 that protrudes from the upper surface 71b and extends in the direction along the Y axis. The first projecting wall 74 can support, for example, the foreign object 120A that has entered the lower rail 21 in a standing or inclined state, and the upper rail 22 can help push the foreign object 120A out of the lower rail 21. Therefore, the foreign matter 120A is prevented from entering between the upper rail 22 and the lower rail 21.

  In the direction along the Y axis, the distance between the protrusion 77 and the first attachment portion 72 is shorter than the distance between the protrusion 77 and the second attachment portion 73. Therefore, the force with which the first attachment portion 72 is pressed against the bottom wall 31 is stronger than the force with which the second attachment portion 73 is pressed against the bottom wall 31 in a state where the projection 77 elastically deforms the plate portion 71. Become. Thus, the first attachment portion 72 of the first attachment portion 72 and the second attachment portion 73 is pressed against the bottom wall 31 with a stronger force, and the first foreign matter interference member 25 and the bottom wall 31 It is possible to further suppress the occurrence of rattling. For example, as in the present embodiment, the protrusion 77 is provided at a position close to the first attachment portion 72 inserted into the first attachment hole 101 with elastic deformation, so that the first foreign object interference member 25 and the bottom The occurrence of rattling with the wall 31 can be further suppressed.

  In the direction along the Z-axis, the distance C1 between the first locking surface 83c and the lower surface 71a is longer than the distance C2 between the locking surface 86a and the lower surface 71a. For this reason, the first locking surface 83c is more easily separated from the bottom surface 31a of the bottom wall 31 than the locking surface 86a. However, when the projection 77 elastically deforms the plate portion 71, the first locking surface 83c is pressed against the bottom surface 31a with a strong force. Accordingly, separation of the first locking surface 83c from the bottom surface 31a is suppressed, and rattling between the first foreign object interference member 25 and the bottom wall 31 is further suppressed.

  When the first mounting portion 72 is inserted into the first mounting hole 101, for example, due to the positional deviation of the first foreign matter interference member 25, the variation of the dimensions, or the displacement of the position and the size of the first mounting hole 101. The first attachment portion 72 may abut on the bottom wall 31. Since the claws 83 extend from the base portion 82 in the direction approaching the lower surface 71 a, the base portion 82 is more likely to abut the bottom wall 31 than the claws 83. The base 82 is less likely to deform than the elastically deformable claw 83. For this reason, it is suppressed that the 1st attaching part 72 is damaged when the 1st attaching part 72 and the bottom wall 31 contact | abut. The free end 83 b of the claw 83 is located near the base end of the first attachment portion 72, and the base 82 and the connection end 83 a of the claw 83 are located near the tip of the first attachment portion 72. For this reason, the connecting end 83 a of the claw 83 is more likely to abut against the bottom wall 31 than the free end 83 b of the claw 83. Since the connection end 83a of the claw 83 is less likely to be deformed than the free end 83b, damage to the first attachment 72 when the first attachment 72 and the bottom wall 31 are in contact with each other is suppressed. As described above, damage to the first foreign object interference member 25 at the time of attachment is suppressed.

  The free end 83 b of the claw 83 is located near the base end of the first mounting portion 72, and the base 82 and the connection end 83 a of the claw 83 are located near the tip of the first mounting portion 72. Therefore, when assembling the slide rail apparatus 11 in a state where the first foreign matter interference member 25 is attached to the bottom wall 31, the connection end 83a of the base 82 or the claw 83 is more than the free end 83b of the claw 83. Is more likely to abut other members such as the carpet of the vehicle 1. Since the base 82 and the connection end 83a of the claw 83 are less likely to be deformed than the free end 83b, the elastic deformation of the claw 83 is suppressed as the first attachment portion 72 comes out of the first mounting hole 101. Unwanted removal of the mounting portion 72 from the bottom wall 31 is suppressed.

  When the first attachment portion 72 is inserted into the first attachment hole 101, the claw 83 elastically deforms in the direction approaching the protrusion 81. The contact of the claw 83 with the projection 81 restricts further elastic deformation of the claw 83. Thereby, the maximum amount of elastic deformation of the claw 83 is limited, and damage to the claw 83 is suppressed.

  The cross-sectional area of the base portion 82 that intersects the Z-axis is larger than the cross-sectional area of the protruding portion 81 that intersects the Z-axis. Therefore, the base portion 82 is less likely to be deformed than the projecting portion 81. Therefore, when the base part 82 collides with the bottom wall 31, it is suppressed that the 1st attaching part 72 is damaged. That is, damage to the first foreign object interference member 25 at the time of attachment is suppressed.

  The second attachment portion 73 is provided on the plate portion 71 at a position separated from the first attachment portion 72 in the direction along the Y axis, and attaches the first foreign matter interference member 25 to the bottom wall 31. As described above, since the first foreign matter interference member 25 is attached to the bottom wall 31 by the first attachment portion 72 and the second attachment portion 73 at a plurality of positions separated in the direction along the Y axis, the first foreign matter The interference member 25 is attached to the bottom wall 31 more reliably.

  The length of the protrusion 81 in the direction along the Y axis is longer than the length of the protrusion 81 in the direction along the X axis. Since the first foreign object interference member 25 is attached to the bottom wall 31 extending in the direction along the Y axis, the first foreign matter interference member 25 can be generally elongated in the direction along the Y axis. For example, when the first foreign matter interference member 25 is attached to the bottom wall 31 due to such a factor, the lower surface 71a is not completely horizontal with respect to the bottom wall 31, and is inclined on the YZ plane. Sometimes. In addition, as in the present embodiment, when the first attachment portion 72 is inserted into the first attachment hole 101, the first foreign object interference member 25 forms the second attachment portion 73 and the second inner circumferential surface 102a. The contact portion with the center of gravity is approximately centered on the YZ plane. At this time, the first attachment portion 72 inserted into the first attachment hole 101 may abut on the bottom wall 31. Furthermore, for example, by the restoring force of the first foreign matter interference member 25 elastically deformed by the projection 77, the claw 83 of the first attachment portion 72 abuts on the bottom wall 31 in the direction of coming out of the first attachment hole 101. In these cases, a force on the YZ plane acts on the protrusion 81. However, since the length of the protrusion 81 in the direction along the Y axis is long, the strength of the protrusion 81 with respect to the force is improved, and the damage of the first attachment portion 72 is suppressed. Furthermore, since the strength of the protrusion 81 is improved without thickening the protrusion 81 as a whole, the cost of the first foreign object interference member 25 can be reduced.

  At least three claws 83 extend radially from the base 82 and in a direction approaching the lower surface 71a. Thus, when the first attachment portion 72 is inserted into the first attachment hole 101, the connection end 83a of one claw 83 extending in at least one direction can abut against the bottom wall 31, and the projection 81 Contact with the bottom wall 31 is suppressed. Therefore, damage to the first attachment portion 72 is suppressed. Furthermore, when the first attachment portion 72 tries to move in the direction of coming out of the first attachment hole 101, one claw 83 extending in at least one direction can abut on the bottom wall 31. Therefore, the first attachment portion 72 is prevented from coming off the bottom wall 31 in an undesired manner.

  The first locking surface 83c of the claw 83 faces the bottom surface 31a, and the second locking surface 83d faces the first inner circumferential surface 101a. As a result, the first attachment portion 72 is prevented from slipping out of the first attachment hole 101, and the first foreign object interference member 25 is directed in the direction along the lower surface 71a with respect to the bottom wall 31. The movement is suppressed, and the occurrence of rattling between the first foreign matter interference member 25 and the bottom wall 31 is suppressed.

  The plurality of claws 83 elastically deformed at the time of insertion into the first mounting hole 101 spread so that the second locking surface 83 d approaches the first inner circumferential surface 101 a by the restoring force. The claw 83 can press the second locking surface 83d against the first inner peripheral surface 101a by the restoring force. As a result, movement of first foreign matter interference member 25 relative to bottom wall 31 in the direction along lower surface 71a is suppressed, and rattle between first foreign matter interference member 25 and bottom wall 31 is generated. Be suppressed.

  The first foreign matter interference member 25 has an opening forming portion 91 provided with a first opening 78 penetrating the first foreign matter interference member 25 and an object inclined portion adjacent to the opening forming portion 91 in the direction along the Y axis. And 92. The first protruding wall 74 is provided on the object inclined portion 92 and has a second end 74b in the direction along the Y axis. The second end 74 b is located at one end of the object inclined portion 92 in the direction along the Y axis. Thus, the first protruding wall 74 does not cover the first opening 78. Therefore, for example, members such as the rivet 105 and the reference pin 106 can pass through the first opening 78 from the upper direction and the lower direction, and the assembly of the slide rail device 11 is facilitated. Furthermore, interference with the first projecting wall 74 with a tool or robot arm passing a member such as the rivet 105 from above to the first opening 78 is suppressed. In addition, it is not necessary to provide a notch in the first projecting wall 74 to avoid a member such as the rivet 105, and the first projecting wall 74 can be made smaller.

  The second projecting wall 75 is provided in the opening forming portion 91 and is provided at a position different from the first opening 78 in the direction along the X axis. The second projecting wall 75 supports, for example, the foreign matter 120A, 120B entering the lower rail 21 in the opening forming portion 91 in a standing or inclined state, and the upper rail 22 brings the foreign matter 120A, 120B out of the lower rail 21. It can help push it out. Accordingly, it is possible to prevent the foreign matters 120A and 120B from entering between the upper rail 22 and the lower rail 21.

  The second projecting wall 75 extends in the direction along the Y axis across the opening forming portion 91 and the object inclined portion 92 without interruption at the boundary between the opening forming portion 91 and the object inclined portion 92. This prevents, for example, the foreign matter 120A, 120B from being caught between the first protruding wall 74 and the second protruding wall 75 in the direction along the Y axis. Furthermore, in the object inclined portion 92, the first projecting wall 74 and the second projecting wall 75 can stably maintain the foreign substances 120A and 120B in a standing or inclined posture.

  The first opening 78 is located between the two second projecting walls 75 in the direction along the X-axis. Thereby, the state where the first opening 78 penetrates the first foreign object interference member 25 is ensured without the second projecting wall 75 covering the first opening 78. Furthermore, since the second projecting wall 75 is provided on both sides of the first opening 78 in the direction along the X axis, the foreign matter 120A, 120B invading the lower rail 21 by the at least one second projecting wall 75 is erected or It can support in the inclined state. Therefore, the intrusion of the foreign matter 120A, 120B between the upper rail 22 and the lower rail 21 is suppressed.

  The first projecting wall 74 is located between the two second projecting walls 75. In the direction along the Z-axis, the length of the first projecting wall 74 is longer than the length of the second projecting wall 75. Thereby, in the object inclined portion 92, the first projecting wall 74 supports the foreign matter 120A, 120B invading the lower rail 21 more securely by raising or tilting, and the upper rail 22 holds the foreign matter 120A, 120B in the lower rail 21. It can help push it out. Accordingly, it is possible to prevent the foreign matters 120A and 120B from entering between the upper rail 22 and the lower rail 21.
