Description

TECHNICAL FIELD The present invention relates to an interior component for a vehicle, such as a console box provided in the passenger compartment of the vehicle.

A console box for storing articles is provided as a vehicle interior accessory between a driver's seat and a passenger's seat that are arranged side by side in the vehicle width direction of the vehicle. As one aspect of this console box, a box main body having a pair of side wall portions arranged in a state spaced apart from each other in the vehicle width direction as fixed portions, and having a storage portion between the side wall portions, and a box body disposed between the side wall portions. Patent Document 1, for example, discloses a tray that is provided with a tray as a movable member that opens and closes the storage portion by being slid in the front-rear direction. A rail portion having a groove extending in the front-rear direction is formed on the inner surface of each side wall portion in the vehicle width direction.

Console boxes of the type described above are generally provided with a positioning mechanism to position and/or assist in positioning the tray. FIG. 9 shows one aspect of the positioning mechanism. As shown in FIG. 9 , the positioning mechanism 60 includes projections 64 , housings 66 , pins 71 and coil springs 74 .

The housing portion 66 is formed in the tray 65 and has a tubular shape extending in the vehicle width direction (horizontal direction). A bottom portion 67 closes the end portion of the housing portion 66 on the far side from the side wall portion 62 (inside the vehicle: left side in FIG. 9). The pin 71 has a pin body 72 and a head 73 . The pin body 72 extends in the vehicle width direction and is inserted through the bottom portion 67 of the housing portion 66 . The pin body 72 is supported by the bottom portion 67 and the coil spring 74 so as to be able to reciprocate in the vehicle width direction. The head portion 73 is formed at the end portion of the pin body 72 on the side closer to the side wall portion 62 (outer side of the vehicle). A portion of the head portion 73 is exposed through an opening at the end of the housing portion 66 on the outside of the vehicle and is engaged with the rail portion 63 . The coil spring 74 is wound around the pin body 72 in a compressed state between the head portion 73 and the bottom portion 67, and biases the pin 71 toward the outside of the vehicle.

The projecting portion 64 has a portion of each rail portion 63 that engages the head portion 73 when the storage portion 61 is closed by the tray 65 and a portion that engages the head portion 73 when the storage portion 61 is largely opened by the tray 65 . It is formed at least at a location where the head 73 is engaged.

In the above-described console box, the head portion 73 slides along the rail portions 63 when an operating force directed in the front-rear direction is applied to the tray 65 . The tray 65 slides forward and backward while being guided by the rail portion 63 .

For example, when the tray 65 is slid in the front-rear direction from the position where the head 73 is engaged with the protrusion 64 as shown in FIG. do. Before the head 73 reaches the top 64t of the protrusion 64, as it approaches the top 64t, the force of the protrusion 64 pressing the head 73 toward the inside of the vehicle increases, and the coil spring 74 is compressed. The force is maximum at the top 64t of the projection 64. As shown in FIG. After the head 73 passes over the top 64t of the protrusion 64, the force with which the protrusion 64 presses the head 73 decreases as the distance from the top 64t increases in the front-rear direction, and the head 73 moves toward the outside of the vehicle. while sliding. The coil spring 74 expands due to its elastic restoring force.

Japanese Unexamined Patent Application Publication No. 2015-98200

However, in the above conventional console box, when the tray 65 is slid forward and backward and the head 73 gets over the projection 64, the pin 71 reciprocates. As the pin 71 reciprocates, the coil spring 74 contracts and then expands vigorously. Both ends of the coil spring 74 in the vehicle width direction are in contact with the head portion 73 of the pin 71 and the bottom portion 67 of the housing portion 66 and are restricted in movement, but an intermediate portion between the ends is restricted in movement. It is in a free state. Therefore, when the coil spring 74 is switched from the contracted state to the expanded state, the intermediate portion of the coil spring 74 may vibrate in the radial direction and generate abnormal noise. Such problems can also occur when a spring of a different type than the coil spring 74 is used to elastically bias the pin. Moreover, the above-mentioned problem can occur in the same way, not only in the console box, as long as it is an interior component for a vehicle that includes a positioning mechanism using a spring in addition to a fixed portion and a movable member.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object of the present invention is to provide a vehicle capable of suppressing abnormal noise caused by spring vibration when a movable member is moved. The purpose is to provide interior goods for automobiles.

A vehicle interior component that solves the above problems includes a fixed portion arranged in a vehicle, a movable member that moves along the fixed portion when operated, and at least one of positioning and positioning assistance of the movable member. The positioning mechanism is supported reciprocally in the intersecting direction by a projecting portion projecting from the fixed portion in a direction intersecting the moving direction of the movable member, and by the movable member. a pin having a head portion formed on the end of the pin body on the fixed portion side so as to slide on the protrusion along with the movement of the movable member; and a spring disposed at a spaced apart position to urge the pin toward the fixed portion, wherein an elastic member made of an elastic material is provided between the pin body and the spring. A member is positioned in contact with the pin body and the spring.

According to the above configuration, when the movable member is operated, the movable member moves together with the pin, the spring, and the elastic member. In the course of this movement, the pin reciprocates in a direction crossing the moving direction of the movable member (intersecting direction), and the head slides on the protrusion. Due to this sliding, a force is generated with which the protrusion presses the head toward the side of the cross direction where the protrusion protrudes from the fixed portion.

Before the head reaches the top of the protrusion, this force increases as it approaches the top. While elastically deforming the spring, the pin moves in the cross direction to the side where the protrusion protrudes. When the head contacts the top of the projection, the force is maximum and the pin travels the maximum. Springs are elastically deformed the most. After the head has passed the top of the protrusion, the force decreases as the distance from the top increases. The spring attempts to return to its original shape due to its elastic restoring force. The original shape is the shape before the head slides over the protrusion. The head slides on the protrusion while moving in the cross direction opposite to the side from which the protrusion protrudes.

As described above, when the head moves over the protrusion as the movable member moves, the pin reciprocates in the crossing direction, and after the spring is elastically deformed, the pin body tries to return to its original shape. Attempt to vibrate radially. However, an elastic member made of an elastic material is arranged between the pin body and the spring. Moreover, the elastic member is in contact with both the pin body and the spring. At the contact point, there is no gap between the elastic member and the spring, and the movement of the spring in the radial direction of the pin body is restricted by the elastic member. Therefore, when the spring returns to its original shape after being elastically deformed, the phenomenon of the spring vibrating in the radial direction of the pin body is restricted, and the generation of abnormal noise caused by the vibration is suppressed.

In the vehicle interior part, the spring is a coil spring that is wound around the pin body, the elastic member is a tubular tube, and the tube is covered over the pin body. It is preferable that the pin body and the coil spring are in contact with each other when the coil spring is attached.

According to the above configuration, when the movable member is operated and the head slides on the protrusion while the movable member moves with the pin, the coil spring, and the tube, the protrusion does not move the head. The force that presses the part is generated.

Before the head reaches the top of the protrusion, this force increases as it approaches the top. While the pin elastically deforms the coil spring to the contracting side, it moves away from the protrusion in the cross direction. After the head has crossed over the top of the projection, the force decreases as the distance from the top increases. The coil spring expands due to its elastic restoring force, and the head slides on the protrusion while moving in the cross direction to the side opposite to the side from which the protrusion protrudes.

As described above, when the head moves over the protrusion as the movable member moves, the pin reciprocates in the cross direction, the coil spring contracts and then expands, and tries to vibrate in the radial direction. However, when the coil spring is attached, a tube made of an elastic material and covering the pin body is in contact with the pin body and the coil spring, restricting radial movement of the coil spring. Therefore, when the coil spring switches from the contracted state to the expanded state, the coil spring is restricted from vibrating in the radial direction.

In the vehicle interior part, it is preferable that the tube is made of rubber, and a slit is formed along the entire length of the tube in a part of the tube in the circumferential direction.

According to the above configuration, the tube is provided with a pair of end portions facing each other in the circumferential direction with the slit interposed therebetween by forming the slit over the entire length of the tube. The tube is elastically deformable in the circumferential direction toward and away from both end portions.

Therefore, it is possible to cover the pin body with the tube through the slit. That is, by applying a force toward both ends of the tube in the circumferential direction, the tube is elastically deformed so that the distance between the ends increases. This elastic deformation widens the distance between the two end portions to a size that allows the pin body to pass through. In this state, the pin body is inserted into the tube through between the two end portions. When the force is stopped from being applied to both ends of the tube, the tube tends to return to its original shape due to the elastic restoring force. The space between the two end portions is narrowed, and the tube is put on the pin body. Therefore, the work of putting the tube over the pin body is easier than when the pin is inserted through the opening at the end of the tube in the length direction.

When the coil spring is attached from the outer peripheral side of the tube to the pin body covered with the tube, the tube and the coil spring interfere with each other. A force is applied from the coil spring to the tube to reduce its diameter. The diameter of the tube is reduced by elastically deforming the tube toward the side where both ends are brought closer. The tube comes into contact with both the pin body and the coil spring.

In the vehicle interior part, it is preferable that a portion of the tube in the circumferential direction is formed of a flat portion extending in the longitudinal direction of the tube.
Here, if the entire tube is formed in a circular tube shape, and if the tube is placed in a high-temperature environment and shrinks (reduces in diameter) due to heat, the outer diameter of the tube will be reduced to that of the coil spring. inner diameter of the coil spring, and the tube may move radially inwardly away from the coil spring.

In this regard, if a portion of the tube in the circumferential direction is composed of a flat portion extending in the longitudinal direction of the tube, as in the above configuration, the flat portion and the curved portion adjacent to the flat portion in the circumferential direction of the tube are formed. Starting from the boundary of the tube, the tube elastically deforms so as to reduce its diameter. The flat portion is less likely to be elastically deformed, and the degree of diameter reduction due to elastic deformation is less than that of a tube having no flat portion and having a circular tubular shape as a whole. Even if the tube shrinks due to heat or the like, it is easy to maintain contact with the coil spring. The deterioration of the function of the tube to restrict radial movement of the coil spring is suppressed, and the effect of suppressing abnormal noise is exhibited.

In the vehicle interior part, the vehicle includes a box body having a pair of side walls arranged in a spaced-apart manner, and a box main body disposed between the side walls in a direction intersecting with the direction in which the side walls are arranged. and a tray that slides to and from the fixed portion, the fixed portion is configured by at least one of the side walls, the movable member is configured by the tray, and the projecting portion is configured to slide the fixed portion. It is preferable that the pin protrudes from the constituting side wall portion toward the opposing side wall portion side, and that the pin is supported by the tray so as to be able to reciprocate in the arrangement direction.

According to the above configuration, when an operating force is applied to the tray, the tray is slid along with the pin, the spring and the elastic member in a direction crossing the arrangement direction of the pair of side wall portions of the box body. In the course of this sliding movement, the head of the pin slides on the projection projecting from the side wall constituting the fixed portion toward the opposing side wall. Due to this sliding, a force is generated with which the protrusion presses the head portion toward the opposing side wall portion. This force increases and decreases before and after the head gets over the protrusion. As this force increases and decreases, the pin reciprocates in the direction in which the side walls are arranged, and the spring returns to its original shape after being elastically deformed.

In the above-mentioned console box as well, the pin reciprocates when the head gets over the protrusion as the tray slides. After the spring is elastically deformed, it tries to vigorously return to its original shape and vibrates in the radial direction. However, the radial vibration of the spring is restricted by the elastic member arranged between the pin body and the spring.

According to the above vehicle interior component, when the movable member is moved, it is possible to suppress the generation of abnormal noise caused by the vibration of the spring.

An embodiment in which a vehicle interior component is embodied in a console box will be described below with reference to FIGS. 1 to 8. FIG.
In the following description, it is assumed that the traveling direction (advance direction) of the vehicle is the front, the backward direction is the rear, and the height direction is the vertical direction. In addition, the vehicle width direction (horizontal direction) is defined with reference to the case where the vehicle is viewed from the rear.

A driver's seat and a front passenger's seat (not shown) are arranged side by side in the vehicle width direction in the front part of the vehicle compartment. The console box of this embodiment is arranged between the driver's seat and the passenger's seat. As shown in FIG. 1, the console box has a box body 10 and a tray 15. As shown in FIG. The box body 10 has a pair of side wall portions 11 arranged in a state of being spaced apart from each other in the vehicle width direction as fixing portions. Between the side wall portions 11, a storage portion 12 having an open upper end is formed. The storage unit 12 stores relatively tall articles such as PET bottles.

As shown in FIGS. 1, 3 and 5, rail portions 13 having grooves 14 extending in the front-rear direction are provided on the inner surfaces of the side wall portions 11 in the vehicle width direction and near the upper portion of the storage portion 12 . formed. The groove 14 for each rail portion 13 is open on the inner surface of the side wall portion 11 .

3, only one (right) rail portion 13 is shown. The pair of rail portions 13 are configured symmetrically at the pair of side wall portions 11 facing each other in the vehicle width direction.
As shown in FIGS. 1 and 2, the tray 15 is arranged between the side walls 11 . By being operated, the tray 15 is slid along both rail portions 13 (side wall portions 11) in the front-rear direction, which is the direction intersecting the direction in which the side wall portions 11 are arranged, so that the storage portion 12 can be moved. It functions as a lid that opens and closes. In this embodiment, the tray 15 is a movable member. The tray 15 has a placing portion 16 for placing small items whose height is lower than the articles stored in the storage portion 12 . The tray 15 includes a pair of side plate portions 17 that sandwich the placement portion 16 from both sides in the vehicle width direction.

The console box further includes a positioning mechanism 20 that positions and assists in positioning the tray 15 .
As shown in FIGS. 1 and 3 , the positioning mechanism 20 has three protrusions 21 , 22 and 23 for each rail portion 13 . Each projection 21 to 23 has the same shape. Of the three protrusions 21 to 23 of each rail portion 13, the two protrusions 21 and 22 on the front side are formed in the front portion of the rail portion 13 adjacent to each other in the front-rear direction. The remaining one projecting portion 23 for each rail portion 13 is formed at the rear portion of the same rail portion 13 . Each of the protrusions 21 to 23 protrudes from the bottom 24 of the rail 13 toward the opposing side wall 11 in a direction (intersecting direction) that intersects the moving direction (front-rear direction) of the tray 15 .

As shown in FIGS. 3 and 4, the protrusions 21 to 23 protrude most from the bottom 24 of the rail 13 at the central portion in the front-rear direction. This portion of each projection 21 to 23 is called a top portion 25. As shown in FIG. The amount of projection of each projection 21 to 23 from the bottom 24 of the rail 13 decreases forward or rearward from the top 25 and becomes minimum (zero) at both ends in the front-rear direction.

As shown in FIGS. 3 to 5, insertion holes 26 are formed in front and rear portions of the side plate portions 17 of the tray 15, respectively. At the periphery of each insertion hole 26 in each side plate portion 17 , an accommodation portion 27 extending from the side plate portion 17 to both sides in the vehicle width direction and having a cylindrical shape as a whole is integrally formed. A bottom portion 28 closes the end portion of each accommodation portion 27 on the inside of the vehicle. On the other hand, the end portion of each housing portion 27 on the outside of the vehicle is open.

A pin 31 having a pin body 32 and a head portion 33 is provided in each accommodation portion 27 . The pin body 32 extends in the vehicle width direction and is inserted through the bottom portion 28 . The pin body 32 has a non-circular cross-sectional shape (see FIG. 6). The pin body 32 is supported by the bottom portion 28 and a coil spring 35 to be described later so as to be able to reciprocate in the vehicle width direction (arrangement direction of the side wall portions 11) as the crossing direction. The head portion 33 is formed integrally with the end portion of the pin body 32 on the outside of the vehicle (on the side wall portion 11 side). A vehicle exterior portion of the head portion 33 is exposed from an opening portion of the housing portion 27 on the vehicle exterior side, and is engaged with the rail portion 13 . The head 33 slides on the protrusions 21 to 23 as the tray 15 moves.

A spring is arranged in each accommodating portion 27 to bias the pin 31 toward the side wall portion 11 having the projections 21 to 23 formed thereon, that is, toward the outside of the vehicle. The spring is located radially outwardly spaced from the pin body 32 . Each spring consists of a coil spring 35 wound around the pin body 32 in a compressed state between the head 33 and the bottom 28 .

Furthermore, in this embodiment, an elastic member made of an elastic material is arranged between the pin body 32 and the coil spring 35 so as to be in contact with the pin body 32 and the coil spring 35 . As the elastic material, rubbers such as EPDM (ethylene propylene diene rubber), elastomers such as TPO (olefin elastomer), TPV (dynamically crosslinked thermoplastic elastomer) can be used.

As shown in FIGS. 4 and 7, the elastic member of this embodiment is constituted by a tube 37 made of rubber and having a tubular shape and covering the pin body 32 .
As shown in FIGS. 6 and 7, a slit 38 is formed along the entire length of the tube 37 at a portion of the tube 37 in the circumferential direction. The position of the slit 38 in the circumferential direction of the tube 37 differs depending on the situation when the tube 37 is put over the pin body 32 . Therefore, in FIGS. 6 and 7, for the sake of convenience, the slit 38 is illustrated assuming that the tube 37 is placed over the pin body 32 so that the slit 38 is positioned above the tube 37 (above the axis L1). ing. By forming the slit 38, the tube 37 is formed with a pair of terminal portions 37a facing each other in the circumferential direction with the slit 38 interposed therebetween. In this embodiment, the tube 37 has an inner diameter larger than the outer diameter of the pin body 32 in a natural state where no force is applied from the outside.

A portion of the tube 37 in the circumferential direction is constituted by a flat portion 39 extending in the longitudinal direction of the tube 37 . In this embodiment, the flat portion 39 is formed over the entire length of the tube 37 . The flat portion 39 is formed on the opposite side of the slit 38 across the axis L1 of the tube 37 . In other words, the flat portion 39 is formed in the central portion of the tube 37 in the circumferential direction.

Both end portions 37a of the tube 37 in the circumferential direction are separated from each other in the same circumferential direction as shown in FIG. When the coil spring 35 is attached to the pin 31 through the tube 37, both the terminal portions 37a are in contact with each other as shown in FIG.

When the coil spring 35 is attached to the pin body 32 via the tube 37 , the inner peripheral surface of the tube 37 is in contact with the outer peripheral surface of the pin body 32 . Further, the outer peripheral surface of the tube 37 is in contact with the coil spring 35 from the inner peripheral side. The contact between the tube 37 and the coil spring 35 is made in a state in which they interfere with each other in the radial direction of the tube 37 by about 0.1 mm. The tube 37 is elastically deformed and recessed at the contact portion with the coil spring 35 .

Furthermore, as shown in FIGS. 1 and 3 , the projection 21 located at the frontmost position of each rail portion 13 is positioned so that when the tray 15 is slid to the position where the storage portion 12 is closed, the head of the pin 31 on the front side is pushed forward. It is formed at a location that contacts the portion 33 from the rear side. Two projections 21 and 22 formed at the front portion of each rail portion 13 and adjacent to each other in the front-rear direction are positioned slightly rearward from the position where the tray 15 closes the storage portion 12 , that is, the position of the storage portion 12 . It is formed at a location where it contacts the head portion 33 of the pin 31 on the front side from both front and rear sides when it is slid to a position where a part (front end) is partially opened. In other words, when the head portion 33 is engaged between the protrusions 21 and 22, the tray 15 is positioned slightly rearward from the position where the storage portion 12 is closed and held at that position. . The protruding portion 23 located at the rearmost position of each rail portion 13 is formed at a portion that contacts the head portion 33 of the pin 31 on the rear side from the front side when the tray 15 is slid to the position where the storage portion 12 is opened. It is The protrusions 21 and 23 cooperate with another positioning means (not shown) to position the tray 15 in the front-rear direction. That is, the protrusions 21 and 23 assist positioning of the tray 15 in the front-rear direction.

Next, the operation of this embodiment configured as described above will be described. In addition, effects caused by the action will also be described.
<Regarding work for attaching the tube 37 to the pin 31>
Here, if the tube 37 does not have the slit 38 and the tube 37 has an annular shape, the pin 31 is inserted into the tube 37 from the opening at the end in the length direction of the tube 37. By doing so, the tube 37 is attached to the pin 31 . However, the opening of the tube 37 has a small diameter. Therefore, it is difficult to insert the pin 31 into the tube 37 through this small-diameter opening.

On the other hand, in this embodiment, as shown in FIG. 6, a slit 38 is formed in a part of the tube 37 in the circumferential direction along the entire length of the tube 37 . The tube 37 is divided in the circumferential direction at the locations where the slits 38 are formed. The tube 37 has a pair of terminal portions 37a formed on both sides of the slit 38 in the circumferential direction. Therefore, it is easy to elastically deform the tube 37 toward and away from the ends 37a.

When the tube 37 is attached to the pin body 32, a force is applied to both end portions 37a of the tube 37 in the circumferential direction so as to move away from each other. This force elastically deforms the tube 37 so that the distance between the two end portions 37a widens. Due to this elastic deformation, the distance between both end portions 37a is widened to a distance through which the pin body 32 can pass.

In this state, the pin body 32 is inserted into the tube 37 from the outside in the radial direction of the tube 37 through between the end portions 37a. After the pin main body 32 is inserted, the application of the force to both terminal portions 37a is stopped. Then, the elastic restoring force causes the tube 37 to return to its original shape. The distance between both terminal portions 37 a is narrowed, and the tube 37 is put on the pin body 32 .

Therefore, the pin body 32 is easier to insert into the tube 37 than when the pin 31 is inserted through the opening at the end of the tube 37 in the longitudinal direction, and the tube 37 is easily attached to the pin 31 .

If the slits 38 are not formed, it is conceivable to use a tube 37 having a diameter larger than that of the pin 31 so that the pin 31 can be easily inserted into the openings at both ends of the tube 37 . However, in this case, when the tube 37 is placed over the pin body 32, a gap is created between the two. Also, the tube 37 may interfere excessively with the coil spring 35 and affect the smooth expansion and contraction of the coil spring 35 . Therefore, there is a limit to increasing the diameter of the tube 37 .

However, by forming the slit 38 as in this embodiment, the tube 37 having an inner diameter larger than the outer diameter of the pin body 32 can be used. In this case, the cross-sectional area of the region surrounded by tube 37 is larger than the cross-sectional area of pin body 32 . Therefore, it is easy to insert the pin main body 32 into the tube 37 through the terminal portions 37a, and the tube 37 can be easily attached to the pin 31. As shown in FIG.

When the coil spring 35 is attached from the outer peripheral side of the tube 37 to the pin body 32 covered with the tube 37, the tube 37 and the coil spring 35 interfere with each other as shown in FIG. A force is applied from the coil spring 35 to the tube 37 to reduce its diameter. The diameter of the tube 37 is reduced by elastically deforming the tube 37 toward the side that brings the both end portions 37a closer to each other. In the present embodiment in which a flat portion 39 is formed in a portion of the tube 37 in the circumferential direction, curved portions 41 having an arcuate cross section are positioned on both sides of the flat portion 39 in the same circumferential direction. The diameter reduction is achieved by elastically deforming each curved portion 41 starting from the boundary portion 42 with the flat portion 39 toward the side that brings the both end portions 37a closer to each other. At this time, the flat portion 39 is difficult to be elastically deformed and tries to maintain a flat state. Therefore, the inner diameter of the tube 37 after the diameter reduction is larger than the inner diameter of the tube 37 when the flat portion 39 is not formed. In the state where the coil spring 35 is mounted, the inner peripheral surface of the tube 37 whose diameter is reduced contacts the outer peripheral surface of the pin body 32, and the outer peripheral surface of the tube 37 is pushed against the coil spring 35 from the inner peripheral side. Contact.

<When tray 15 is slid>
When the tray 15 has the storage portion 12 fully opened, the head portion 33 of the pin 31 on the rear side of each side plate portion 17 is engaged with the projection portion 23 from the rear side. When partially or wholly closing the storage section 12 from this state, an operating force directed forward is applied to the tray 15 .

Further, when the tray 15 opens only the front end of the storage portion 12, the head portion 33 of the pin 31 on the front side of each side plate portion 17 is engaged between the protrusions 21 and 22, and the tray 15 is opened. is held (positioned) at that position. When the storage portion 12 is to be fully opened from this state, a rearward operating force is applied to the tray 15 . Further, when the storage portion 12 is to be closed from the above state, an operating force directed forward is applied to the tray 15 .

Further, when the tray 15 closes the storage portion 12, the head portion 33 of the front pin 31 of each side plate portion 17 is engaged with the projection portion 21 from the front side. From this state, when partially or wholly opening the storage section 12 , an operation force directed toward the rear is applied to the tray 15 .

As described above, when a forward or rearward operating force is applied to the tray 15, the tray 15 slides in the same direction together with the pin 31, the coil spring 35 and the tube 37. As shown in FIG. In the course of this sliding movement, the head 33 slides over the protrusions 21-23. This sliding causes the projections 21 to 23 to generate a force that presses the head 33 from the side wall 11 on which the projections 21 to 23 are provided toward the opposing side wall 11 side.

As shown in FIGS. 4 and 8, before the head portion 33 reaches the top portion 25 of the protrusions 21 to 23, this force increases as the top portion 25 is approached. The pin 31 elastically deforms to contract the coil spring 35 , that is, moves toward the opposing side wall portion 11 side while compressing the coil spring 35 . As this amount of movement increases, the amount of elastic deformation of the coil spring 35 increases. When the head 33 contacts the tops 25 of the protrusions 21 to 23 (see FIG. 8), the above force is maximized, the amount of movement of the pin 31 is maximized, and the coil spring 35 is elastically deformed the most. . After the head 33 has passed over the apex 25 of the projections 21 to 23, the force decreases as the distance from the apex 25 increases. As the coil spring 35 expands due to its elastic restoring force and attempts to return to its original shape, the head portion 33 moves to the side opposite to the side from which the projections 21 to 23 protrude, while the projections 21 to 23 extend. slide up. Coil spring 35 expands and approaches its original shape.

As described above, when the head portion 33 gets over the protrusions 21 to 23 as the tray 15 slides, the pin 31 reciprocates in the vehicle width direction. After the coil spring 35 is elastically deformed, it tries to return to its original shape and vibrates in the radial direction of the pin body 32 . That is, the coil spring 35 expands after being contracted and tries to vibrate in the radial direction.

However, a tubular tube 37 made of an elastic material and covering the pin body 32 is arranged between the pin body 32 and the coil spring 35 . The inner peripheral surface of the tube 37 contacts the outer peripheral surface of the pin body 32, and the outer peripheral surface of the tube 37 contacts the coil spring 35 from the inner peripheral side, that is, in a pressure contact state. At the portion where the tube 37 and the coil spring 35 contact each other, there is no gap between them in which the coil spring 35 can move, and the movement of the coil spring 35 in the radial direction of the pin body 32 is restricted by the tube 37 . Therefore, the phenomenon that the coil spring 35 vibrates in the radial direction of the pin body 32 is restricted when the coil spring 35 returns to its original shape after being elastically deformed, that is, when switching from the contracted state to the expanded state. As a result, it is possible to suppress the generation of noise caused by radial vibration of the coil spring 35 .

Note that the tube 37 interferes with the coil spring 35 from the inner peripheral side. However, since the tube 37 is elastically deformed and the amount of interference is as small as about 0.1 mm in the radial direction of the pin body 32, the influence of the interference on the expansion and contraction operation of the coil spring 35 can be ignored. small.

According to this embodiment, the following effects are obtained in addition to the above.
The effect of suppressing the vibration of the coil spring 35 to suppress the generation of abnormal noise can also be obtained by interposing felt between the pin body 32 and the coil spring 35 . In this case, the felt is wrapped around the pin body 32 to attach it, but the pin body 32 has a small diameter and the felt is small, which makes the work difficult.

In this regard, in this embodiment, a tube 37 made of rubber is arranged between the pin body 32 and the coil spring 35 . Moreover, the tube 37 in which the slit 38 is formed is used. Therefore, as described above, by inserting the pin main body 32 into the tube 37 through the slit 38 while elastically deforming the tube 37 so as to widen the distance between the two end portions 37a, the tube 37 is inserted into the pin 31. can be worn on The work of wrapping the tube 37 around the pin body 32 and attaching it is unnecessary. Therefore, as compared with the case of using felt as described above, it is easier to take measures to suppress the generation of abnormal noise due to the vibration of the coil spring 35 .

The pin 31 is urged by the coil spring 35 toward the adjacent side wall 11 and the head 33 is pressed against the rail 13 when the tray 15 is stopped or slid. Therefore, rattling of the tray 15, particularly rattling in the vehicle width direction, can be suppressed, and noise and vibration can be suppressed.

If the flat portion 39 were not formed and the entire tube 37 was formed in a cylindrical shape, the tube 37 would be placed in a high-temperature environment and contracted (diameter-reduced) due to heat or the like. In this case, the outer diameter of the tube 37 may become smaller than the inner diameter of the coil spring 35 , and the outer peripheral surface of the tube 37 may be separated from the coil spring 35 radially inward. In this case, the function of the tube 37 to restrict the movement of the coil spring 35 in the radial direction is deteriorated, and there is a possibility that the effect of suppressing abnormal noise will not be sufficiently exhibited.

In this regard, in this embodiment, a portion of the tube 37 in the circumferential direction is constituted by a flat portion 39 extending in the longitudinal direction of the tube 37 . Therefore, in the circumferential direction of the tube 37 , the tube 37 elastically deforms so as to reduce its diameter starting from the boundary portion between the flat portion 39 and the adjacent curved portion 41 . The flat portion 39 is less likely to be elastically deformed to reduce its diameter, and the degree of diameter reduction due to the elastic deformation of the flat portion 39 is lower than that of a flat portion 39 that is not provided and has a circular tubular shape as a whole. less. Tube 37 tends to contact coil spring 35 at flat portion 39 . In particular, in the present embodiment, the flat portion 39 is formed on the opposite side of the slit 38 across the axis L1 of the tube 37 and positioned at the central portion of the tube 37 in the circumferential direction. Therefore, the circumferential lengths of both curved portions 41 are the same or substantially the same. The tube 37 is elastically deformed to the same extent on both sides of the flat portion 39 in the circumferential direction and is reduced in diameter. Therefore, when the tube 37 is elastically deformed, the diameter of the tube 37 is reduced in a well-balanced manner in the circumferential direction.

As a result, even if the tube 37 shrinks (reduces in diameter) due to heat or the like, the flat portion 39 of the tube 37 easily maintains contact with the coil spring 35 . It is possible to suppress deterioration in the function of the tube 37 to restrict radial movement of the coil spring 35 and maintain the effect of suppressing abnormal noise.

It should be noted that the above-described embodiment can also be implemented as a modified example in which this is changed as follows. The above embodiments and the following modifications can be combined with each other within a technically consistent range.

The flat portion 39 of the tube 37 does not necessarily have to be formed over the entire length of the tube 37, and may be formed only partially along the length of the tube 37. Also in this case, contraction (reduction in diameter) of the tube 37 due to heat or the like can be suppressed.

- The flat portion 39 may be formed at a plurality of locations in the circumferential direction of the tube 37 .
- One or both of the slit 38 and the flat portion 39 in the tube 37 may be omitted.
