Description

The present invention relates to interior parts for vehicles such as console boxes provided in the passenger compartment of a vehicle.

A console box for storing articles is provided as an interior component for the vehicle between the driver's seat and the passenger seat, which are arranged side by side in the vehicle width direction of the vehicle interior. As one aspect of this console box, a pair of side wall portions arranged in a state of being separated from each other in the vehicle width direction are provided as fixing portions, and the box main body having a storage portion between both side wall portions and arranged between both side wall portions. Patent Document 1, for example, describes a tray provided as a movable member that opens and closes the storage portion by being slid and moved 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.

The console box of the above type is generally provided with a positioning mechanism that performs at least one of tray positioning and positioning assistance. FIG. 9 shows one aspect of the positioning mechanism. As shown in FIG. 9, the positioning mechanism 60 includes a protrusion 64, an accommodating portion 66, a pin 71, and a coil spring 74.

The accommodating portion 66 is formed on the tray 65 and has a tubular shape extending in the vehicle width direction (left-right direction). The end of the accommodating portion 66 on the side far from the side wall portion 62 (inside the vehicle: the left side in FIG. 9) is closed by the bottom portion 67. The pin 71 includes 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 accommodating portion 66. The pin body 72 is supported by a bottom portion 67 and a coil spring 74 so as to be reciprocating in the vehicle width direction. The head 73 is formed at the end of the pin body 72 on the side closer to the side wall 62 (outside the vehicle). A part of the head 73 is exposed from the opening portion of the outer end portion of the accommodating portion 66 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 73 and the bottom 67, and urges the pin 71 to the outside of the vehicle.

The protrusion 64 is a portion of each rail portion 63 where the head 73 is engaged when the storage portion 61 is closed by the tray 65, and when the storage portion 61 is largely opened by the tray 65. It is formed at least at a position where the head 73 is engaged.

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

When the tray 65 is slid and moved in the front-rear direction from the position where the head 73 engages with the protrusion 64, for example, as shown in FIG. 9, the head 73 slides on the protrusion 64. To do. Before the head 73 reaches the top 64t of the protrusion 64, the force with which the protrusion 64 presses the head 73 inward increases as the head 73 approaches the top 64t, and the coil spring 74 is compressed. The above force is maximized at the top 64t of the protrusion 64. After the head 73 exceeds the top 64t of the protrusion 64, the force of the protrusion 64 pressing the head 73 decreases as the head moves away from the top 64t in the front-rear direction, and the head 73 moves to the outside of the vehicle. Sliding while. The coil spring 74 extends due to the elastic restoring force.

JP 2015-98200

However, in the conventional console box, the pin 71 reciprocates when the tray 65 is slid in the front-rear direction and the head 73 gets over the protrusion 64. With the reciprocating movement of the pin 71, the coil spring 74 contracts and then vigorously expands. Both ends of the coil spring 74 in the vehicle width direction are in contact with the head 73 of the pin 71 and the bottom 67 of the accommodating portion 66 to restrict movement, but the intermediate portion between both ends is restricted from moving. It is in a free state. Therefore, when the coil spring 74 is switched from the contracted state to the extended state, the intermediate portion of the coil spring 74 may vibrate in the radial direction and generate an abnormal noise. These problems can also occur when a different type of spring than the coil spring 74 is used to elastically urge the pins. Further, the above problem may occur not only in the console box but also in the case of a vehicle interior product provided with a positioning mechanism using a spring in addition to the fixed portion and the movable member.

The present invention has been made in view of such circumstances, and an object of the present invention is a vehicle capable of suppressing generation of abnormal noise due to vibration of a spring when a movable member is moved. To provide interior parts for use.

A vehicle interior product that solves the above problems includes a fixed portion arranged in the vehicle, a movable member that moves along the fixed portion by being operated, and at least one of positioning and positioning assistance of the movable member. The positioning mechanism is provided with a positioning mechanism to be performed, and the positioning mechanism is supported by a protrusion protruding from the fixed portion in a direction intersecting the moving direction of the movable member and the movable member so as to be reciprocally reciprocating in the intersecting direction. A pin having a pin body and having a head formed on an end of the pin body on the fixed portion side, which slides on the protrusion as the movable member moves, and a pin in the radial direction from the pin body. It is an interior product for a vehicle provided with a spring which is arranged at a position separated from the pin and urges the pin to the fixed portion side, and an elasticity formed of an elastic material between the pin body and the spring. The member is arranged in contact with the pin body and the spring.

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

This force increases as the head approaches the apex of the protrusion before it reaches the apex. While the pin elastically deforms the spring, it moves to the side where the protrusion protrudes in the above-mentioned crossing direction. When the head comes into contact with the top of the protrusion, the above force is maximized and the amount of movement of the pin is maximized. The spring is most elastically deformed. After the head crosses the top of the protrusion, the force decreases as the distance from the top increases. The spring tries to return to its original shape due to the elastic restoring force. The original shape is the shape before the head slides on the protrusion. The head slides on the protrusion while moving to the side opposite to the side where the protrusion protrudes in the above-mentioned crossing direction.

As described above, when the head gets over the protrusion due to the movement of the movable member, the pin reciprocates in the above-mentioned crossing direction, the spring is elastically deformed, and then the pin body tries to return to its original shape. Attempts to vibrate in the radial direction. However, an elastic member formed 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 regulated by the elastic member. Therefore, when the spring elastically deforms and then returns to its original shape, the phenomenon that the spring vibrates in the radial direction of the pin body is regulated, and the generation of abnormal noise due to the vibration is suppressed.

In the vehicle interior product, the spring is composed of a coil spring mounted around the pin body, the elastic member is composed of a tubular tube, and the tube is covered with the pin body. It is preferable that the pin body and the coil spring are in contact with the coil spring attached.

According to the above configuration, when the movable member is operated and the head slides on the protrusion in the process of moving the movable member with the pin, the coil spring and the tube, the protrusion is the head. The above-mentioned force for pressing the portion is generated.

This force increases as the head approaches the apex of the protrusion before it reaches the apex. The pin elastically deforms to the side where the coil spring contracts, and moves to the side away from the protrusion in the above-mentioned crossing direction. After the head has crossed the top of the protrusion, the force decreases as the distance from the top of the protrusion increases. The coil spring is extended by the elastic restoring force, and the head slides on the protrusion while moving to the side opposite to the side where the protrusion protrudes in the above crossing direction.

As described above, when the head gets over the protrusion with the movement of the movable member, the pin reciprocates in the crossing direction, the coil spring contracts and then expands, and tries to vibrate in the radial direction. However, in the state where the coil spring is attached, the tube formed in a tubular shape by the elastic material and covered with the pin body is in contact with the pin body and the coil spring, and restricts the radial movement of the coil spring. Therefore, when the coil spring switches from the contracted state to the extended state, the coil spring is restricted from vibrating in the radial direction.

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

According to the above configuration, by forming a slit in the tube over the entire length, a pair of terminal portions facing each other in the circumferential direction are formed in the tube. The tube can be elastically deformed in the circumferential direction to the side where both end portions are brought close to each other and separated from each other.

Therefore, it is possible to cover the pin body with the tube through the slit. That is, by applying a force to both end portions of the tube toward the side away from each other in the circumferential direction, the tube is elastically deformed so that the distance between the two end portions is widened. Due to this elastic deformation, the distance between the two terminals is widened to a size that allows the pin body to pass through. In this state, the pin body is inserted into the tube through between both terminals. When the above force is stopped applied to both ends of the tube, the tube tries to return to its original shape due to the elastic restoring force. The distance between both terminals is narrowed, and the tube is put on the pin body. Therefore, it is easier to put the tube on the pin body as compared with the case where the pin is inserted from the opening portion of the end portion in the length direction of the tube.

When the coil spring is attached to the pin body covered with the tube from the outer peripheral side of 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 terminals are brought close to each other. The tube is in contact with both the pin body and the coil spring.

In the vehicle interior product, it is preferable that a part of the tube in the circumferential direction is composed of a flat portion extending in the length direction of the tube.
Here, if the entire tube is formed into a circular tube, if the tube is placed in a high temperature environment and contracts (reduced in diameter) due to heat or the like, the outer diameter of the tube becomes a coil spring. The tube may be radially inwardly separated from the coil spring as it becomes smaller than the inner diameter of.

In this regard, as described above, when a part of the tube in the circumferential direction is composed of a flat portion extending in the length direction of the tube, the flat portion and the curved portion adjacent to the flat portion are formed in the circumferential direction of the tube. The tube is elastically deformed so as to shrink in diameter, starting from the boundary portion of. The flat portion is less likely to be elastically deformed, and the degree of diameter reduction due to the elastic deformation is smaller than that of a flat portion 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 the state of contact with the coil spring. The deterioration of the function of the tube to regulate the radial movement of the coil spring is suppressed, and the effect of suppressing abnormal noise is exhibited.

In the vehicle interior product, the vehicle has a box body having a pair of side wall portions arranged in a state of being separated from each other, and a direction in which the box main body is arranged between the side wall portions and intersects with the arrangement direction of the both side wall portions. A console box with a tray that slides to is provided, the fixing portion is composed of at least one of the side wall portions, the movable member is composed of the tray, and the protrusion portion holds the fixing portion. It is preferable that the pin projects from the constituent side wall portion toward the opposite side wall portion, and the pin is supported by the tray so as to be reciprocally reciprocating in the arrangement direction.

According to the above configuration, when an operating force is applied to the tray, the tray slides with a pin, a spring, and an elastic member in a direction intersecting the arrangement direction of the pair of side wall portions in the box body. In the process of this slide movement, the head of the pin slides on a protrusion protruding from the side wall portion constituting the fixing portion toward the opposite side wall portion. Due to this sliding, a force is generated in which the protrusion presses the head toward the opposite side wall. This force increases and decreases before and after the head gets over the protrusion. As this force increases or decreases, the pins reciprocate in the arrangement direction of the wall portions on both sides, and the spring elastically deforms and then returns to its original shape.

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

According to the vehicle interior product, it is possible to suppress the generation of abnormal noise due to the vibration of the spring when the movable member is moved.

Hereinafter, an embodiment in which a vehicle interior component is embodied in a console box will be described with reference to FIGS. 1 to 8.
In the following description, the traveling direction (forward direction) of the vehicle will be the front, the reverse direction will be the rear, and the height direction will be the vertical direction. Further, regarding the vehicle width direction (horizontal direction), the direction is defined based on the case where the vehicle is viewed from the rear.

At the front of the vehicle interior, a driver's seat and a passenger seat (not shown) are installed so as to be arranged in the vehicle width direction. The console box of the present embodiment is arranged between the driver's seat and the passenger seat. As shown in FIG. 1, the console box includes a box body 10 and a tray 15. The box body 10 includes a pair of side wall portions 11 arranged in a state of being separated from each other in the vehicle width direction as fixed portions. A storage portion 12 having an open upper end is formed between the side wall portions 11. A relatively high article such as a PET bottle is stored in the storage unit 12.

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

In FIG. 3, only one (right side) rail portion 13 is shown. The pair of rail portions 13 are symmetrically configured on 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 wall portions 11. By operating the tray 15, the storage portion 12 is moved by sliding along both rail portions 13 (side wall portions 11) in the front-rear direction, which is a direction intersecting the arrangement direction of the wall portions 11 on both sides. It has a function as a lid that opens and closes. In the present embodiment, the tray 15 is a movable member. The tray 15 includes a mounting portion 16 for placing small items having a height lower than that of the articles stored in the storage portion 12. The tray 15 includes a pair of side plate portions 17 that sandwich the mounting portion 16 from both sides in the vehicle width direction.

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

As shown in FIGS. 3 and 4, each of the protruding portions 21 to 23 protrudes most from the bottom portion 24 of the rail portion 13 in the central portion in the front-rear direction. This portion of each protrusion 21 to 23 is referred to as a top 25. The amount of protrusion of each of the protrusions 21 to 23 from the bottom 24 of the rail portion 13 decreases as the distance from the top 25 increases forward or backward, and becomes the minimum (zero) at both ends in the front-rear direction.

As shown in FIGS. 3 to 5, insertion holes 26 are formed in the front portion and the rear portion of each side plate portion 17 in the tray 15. In each side plate portion 17, on the peripheral edge portion of each insertion hole 26, an accommodating portion 27 extending from the side plate portion 17 to both sides in the vehicle width direction and forming a tubular shape as a whole is integrally formed. The inner end of each housing 27 is closed by a bottom 28. On the other hand, the outer end of each accommodating portion 27 is open.

Each accommodating portion 27 is provided with a pin 31 provided with a pin body 32 and a head 33. 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 a bottom portion 28 and a coil spring 35, which will be described later, so as to be able to reciprocate in the vehicle width direction (arrangement direction of both side wall portions 11) as the crossing direction. The head 33 is integrally formed at the end of the pin body 32 on the outside of the vehicle (side of the side wall portion 11). The vehicle outer portion of the head 33 is exposed from the vehicle outer opening portion of the accommodating portion 27 and is engaged with the rail portion 13. The head 33 slides on the protrusions 21 to 23 as the tray 15 moves.

In each accommodating portion 27, a spring for urging the pin 31 to the side wall portion 11 side on which the protrusions 21 to 23 are formed, that is, to the outside of the vehicle is arranged. The spring is arranged at a position separated outward from the pin body 32 in the radial direction. Each spring is composed of a coil spring 35 that is wound around and mounted on the pin body 32 in a compressed state between the head 33 and the bottom 28.

Further, in the present embodiment, an elastic member formed of an elastic material is arranged between the pin body 32 and the coil spring 35 in a state of being in contact with the pin body 32 and the coil spring 35. As the elastic material, rubber such as EPDM (ethylene propylene diene rubber) and elastomer such as TPO (olefin elastomer) and TPV (dynamically crosslinked thermoplastic elastomer) can be used.

As shown in FIGS. 4 and 7, the elastic member of the present embodiment is formed of a tube 37 which is formed in a tubular shape by rubber and is covered with a pin body 32.
As shown in FIGS. 6 and 7, a slit 38 is formed in a part of the tube 37 in the circumferential direction over the entire length of the tube 37. 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 on the pin body 32. Therefore, in FIGS. 6 and 7, for convenience, the slit 38 is shown assuming that the slit 38 is placed on the pin body 32 so that the slit 38 is located above the tube 37 (above the axis L1). ing. Due to the formation of the slit 38, a pair of terminal portions 37a facing each other in the circumferential direction with the slit 38 interposed therebetween are formed in the tube 37. In the present embodiment, as the tube 37, a tube 37 having an inner diameter larger than the outer diameter of the pin body 32 is used in a natural state where no external force is applied.

A part of the tube 37 in the circumferential direction is composed of a flat portion 39 extending in the length direction of the tube 37. In the present embodiment, the flat portion 39 is formed over the entire length of the tube 37. Further, the flat portion 39 is formed on the side opposite to the slit 38 with the axis L1 of the tube 37 interposed therebetween. In other words, the flat portion 39 is formed in the central portion of the tube 37 in the circumferential direction.

Both terminal portions 37a of the tube 37 in the circumferential direction are separated from each other in the circumferential direction as shown in FIG. 6 in a state before the coil spring 35 is attached to the pin 31 via the tube 37. Further, both terminal portions 37a are in contact with each other as shown in FIG. 7 in a state where the coil spring 35 is attached to the pin 31 via the tube 37.

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 performed in a state where the tube 37 interferes with each other by about 0.1 mm in the radial direction. The tube 37 is elastically deformed and recessed at the contact portion with the coil spring 35.

Further, as shown in FIGS. 1 and 3, the foremost protrusion 21 of each rail portion 13 is the head of the pin 31 on the front side when the tray 15 is slid to the position where the storage portion 12 is closed. It is formed at a position where it comes into contact with the portion 33 from the rear side. Further, the two protrusions 21 and 22 formed on the front portion of each rail portion 13 and adjacent to each other in the front-rear direction are located at a position slightly rearward from the position where the tray 15 closes the storage portion 12, that is, the storage portion 12. It is formed at a position where it comes into contact with the head 33 of the front pin 31 from both front and rear sides when a part (front end portion) is slid to a position where it is partially opened. In other words, when the head 33 is engaged between the two protrusions 21 and 22, the tray 15 is positioned at a position slightly rearward from the position where the storage portion 12 is closed, and is held at that position. .. The protrusion 23 located at the rearmost position of each rail portion 13 is formed at a position where the tray 15 comes into contact with the head 33 of the pin 31 on the rear side from the front side when the tray 15 is slid to a position where the storage portion 12 is opened. Has been done. 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 in positioning the tray 15 in the front-rear direction.

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

On the other hand, in the present embodiment, as shown in FIG. 6, a slit 38 is formed in a part of the tube 37 in the circumferential direction over the entire length of the tube 37. At the location where the slit 38 is formed, the tube 37 is divided in the circumferential direction. In the tube 37, a pair of terminal portions 37a are formed on both sides of the slit 38 in the circumferential direction. From this, it is easy to elastically deform the tube 37 toward the side where both terminal portions 37a are brought close to each other and separated from each other.

When the tube 37 is attached to the pin body 32, a force is applied to both end portions 37a of the tube 37 toward the side away from each other in the circumferential direction. This force elastically deforms the tube 37 so that the distance between the two end portions 37a is widened. Due to this elastic deformation, the distance between the two terminal portions 37a is expanded 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 two terminal portions 37a. Then, after the insertion of the pin body 32, 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 the two terminal portions 37a is narrowed, and the tube 37 is put on the pin body 32.

Therefore, as compared with the case where the pin 31 is inserted from the opening portion of the end portion in the length direction of the tube 37, the pin body 32 can be easily inserted into the tube 37, and the tube 37 can be easily attached to the pin 31.

Further, when the slit 38 is not formed, it is conceivable to use a tube 37 having a diameter larger than that of the pin 31 in order to facilitate insertion of the pin 31 into the openings at both ends of the tube 37. However, in this case, a gap is created between the tube 37 and the pin body 32 while the tube 37 is covered with the pin body 32. Further, the tube 37 may excessively interfere with the coil spring 35, which may affect the smooth expansion / contraction operation 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 the present embodiment, a 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 the tube 37 is larger than the cross-sectional area of the pin body 32. Therefore, it is easy to insert the pin body 32 into the tube 37 through both terminal portions 37a, and the mounting workability of the tube 37 to the pin 31 is good.

When the coil spring 35 is attached to the pin body 32 covered with the tube 37 from the outer peripheral side of 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 the diameter of the tube 37. The tube 37 is elastically deformed toward the side where both terminal portions 37a are brought close to each other, so that the diameter of the tube 37 is reduced. In the present embodiment in which the flat portion 39 is formed in a part of the tube 37 in the circumferential direction, curved portions 41 having an arcuate cross section are located 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 from the boundary portion 42 with the flat portion 39 to the side where both terminal portions 37a are brought close to each other. At this time, the flat portion 39 is less likely 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. When the coil spring 35 is attached, the inner peripheral surface of the reduced diameter tube 37 comes into contact with the outer peripheral surface of the pin body 32, and the outer peripheral surface of the tube 37 is from the inner peripheral side with respect to the coil spring 35.

When the tray 15 is in the fully open state of the storage portion 12, the head 33 of the pin 31 on the rear side of each side plate portion 17 is engaged with the protrusion 23 from the rear side. When the storage unit 12 is partially or completely closed from this state, a forward operating force is applied to the tray 15.

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

Further, when the tray 15 closes the storage portion 12, the head 33 of the pin 31 on the front side of each side plate portion 17 is engaged with the protrusion 21 from the front side. When the storage unit 12 is partially or completely opened from this state, a rearward operating force is applied to the tray 15.

When an operating force is applied to the tray 15 in the forward or backward direction as described above, the tray 15 slides in the same direction with the pin 31, the coil spring 35, and the tube 37. In the process of this slide movement, the head 33 slides on the protrusions 21 to 23. Due to this sliding, a force is generated by the protrusions 21 to 23 to press the head 33 from the side wall portion 11 provided with the protrusions 21 to 23 toward the side wall portion 11 facing the side wall portion 11.

As shown in FIGS. 4 and 8, this force increases as the head 33 approaches the apex 25 of the protrusions 21 to 23 before reaching the apex 25. The pin 31 elastically deforms to the side where the coil spring 35 is compressed, that is, moves to the side of the side wall portion 11 which faces the coil spring 35 while compressing the coil spring 35. As the amount of movement increases, the amount of elastic deformation of the coil spring 35 increases. When the head 33 comes into contact with the top 25 of the protrusions 21 to 23 (see FIG. 8), the force is maximized, the amount of movement of the pin 31 is maximized, and the coil spring 35 is elastically deformed most. .. After the head 33 exceeds the top 25 of the protrusions 21 to 23, the force decreases as the distance from the top 25 increases. As the coil spring 35 expands due to the elastic restoring force and tries to return to the original shape, the head 33 moves to the side opposite to the side where the protrusions 21 to 23 protrude, and the protrusions 21 to 23 Slide on. The coil spring 35 expands and approaches the original shape.

As described above, when the head 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 contracts and then expands to try to vibrate in the radial direction.

However, between the pin body 32 and the coil spring 35, a tubular tube 37 formed of an elastic material and covered with the pin body 32 is arranged. The inner peripheral surface of the tube 37 is in contact with the outer peripheral surface of the pin body 32, and the outer peripheral surface of the tube 37 is in contact with 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 come into contact with each other, there is no movable gap between the coil spring 35, and the movement of the coil spring 35 in the radial direction of the pin body 32 is regulated by the tube 37. Therefore, when the coil spring 35 returns to its original shape after being elastically deformed, that is, when the coil spring 35 switches from the contracted state to the extended state, the phenomenon that the coil spring 35 vibrates in the radial direction of the pin body 32 is regulated. As a result, it is possible to suppress the generation of abnormal noise caused by the radial vibration of the coil spring 35.

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 can be obtained in addition to the above.
The above effect of suppressing the vibration of the coil spring 35 and suppressing 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 attached while being wound around the pin body 32, but the work is difficult because the pin body 32 has a small diameter and the felt is small.

In this respect, in the present embodiment, the tube 37 made of rubber is arranged between the pin body 32 and the coil spring 35. Moreover, a tube 37 having a slit 38 formed therein is used. Therefore, as described above, the pin body 32 is inserted into the tube 37 through the slit 38 while the tube 37 is elastically deformed so that the distance between the two terminal portions 37a is widened, so that the tube 37 is inserted into the pin 31. Can be attached to. There is no need to wrap the tube 37 around the pin body 32 and attach it. Therefore, as compared with the case of using felt as described above, it is easy to take measures to suppress the generation of abnormal noise due to the vibration of the coil spring 35.

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

-Here, if the flat portion 39 is not formed and the entire tube 37 is formed into a circular tube, the tube 37 is placed in a high temperature environment and contracts (diameter reduction) due to heat or the like. If this is the case, the outer diameter of the tube 37 may be 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 inward in the radial direction. In this case, the function of the tube 37 to regulate the radial movement of the coil spring 35 is reduced, and the effect of suppressing abnormal noise may not be sufficiently exhibited.

In this respect, in the present embodiment, a part of the tube 37 in the circumferential direction is composed of a flat portion 39 extending in the length direction of the tube 37. Therefore, in the circumferential direction of the tube 37, the tube 37 is elastically deformed so that the diameter of the tube 37 is reduced, starting from the boundary portion between the flat portion 39 and the curved portion 41 adjacent to the flat portion 39. In the flat portion 39, elastic deformation such as shrinking the diameter is unlikely to occur, and the degree of diameter reduction due to the elastic deformation of the flat portion 39 is higher than that in which the flat portion 39 is not provided and the entire flat portion has a circular tubular shape. Less. The tube 37 easily comes into contact with the coil spring 35 at the flat portion 39. In particular, in the present embodiment, the flat portion 39 is formed on the opposite side of the slit 38 with the axis L1 of the tube 37 interposed therebetween, and is located at the central portion of the tube 37 in the circumferential direction. Therefore, the peripheral lengths of both curved portions 41 are the same or substantially the same as each other. The tube 37 is elastically deformed to the same extent on both sides of the flat portion 39 in the circumferential direction to reduce its 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, the tube 37 can easily maintain a state of being in contact with the coil spring 35 at the flat portion 39 even if the tube 37 contracts (reduces its diameter) due to heat or the like. It is possible to suppress the deterioration of the function of the tube 37 to regulate the radial movement of the coil spring 35 and maintain the effect of suppressing abnormal noise.
