Description

[Technical Field]

[0001] The present disclosure relates to vehicle interior trim. [Background technology]

[0002] A known vehicle interior part includes a first member, a second member, and a coil spring, which function as follows: The first member is capable of moving toward and away from the second member. The coil spring is disposed between the first member and the second member and biases the first member in a direction away from the second member. An example of such a vehicle interior part is a console box.

[0003] As disclosed in Patent Document 1, a console box includes a lid for opening and closing an opening of a box body, a pivot shaft provided on the lid, and a bearing provided on the box body for rotatably supporting the pivot shaft. One of the pivot shaft and the bearing can move away from the other and is biased toward it by a coil spring. In the console box, for example, the bearing functions as a first member and the box body functions as a second member. The coil spring biases the bearing toward the pivot shaft of the lid.

[0004] The bearing portion protrudes from the box body due to the biasing force of the coil spring, and moves to a position where it rotatably supports the rotation shaft of the lid. At this time, the rotation shaft of the lid is rotatably supported by the bearing portion. The lid opens and closes the opening of the box body by rotating around the center line of the rotation shaft. Furthermore, the bearing portion moves against the biasing force of the coil spring, and is positioned away from the rotation shaft of the lid. At this time, the lid can be removed from the opening by moving it from the position where it closes the opening of the box body to another position. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2023-70037 Summary of the Invention [Problem to be solved by the invention]

[0006] When the bearing member is moved relative to the box body, the coil spring expands and contracts, causing the coil spring to vibrate finely and producing abnormal noise.

[0007] These problems are also common to vehicle interior parts other than console boxes, that is, vehicle interior parts that include a first member, a second member, and a coil spring. [Means for solving the problem]

[0008] Next, various aspects of vehicle interior parts that solve the above problems will be described. (Aspect 1) a vehicle interior trim comprising a first member, a second member, and a coil spring, wherein the first member is movable toward and away from the second member, the coil spring being disposed between the first member and the second member and biasing the first member in a direction away from the second member; the vehicle interior trim comprises a side surface portion facing a side of the coil spring and extending in the direction of movement of the first member, the first member and the second member having retaining portions with which axial ends of the coil spring contact, the retaining portions being formed such that when the coil spring contracts from and extends toward its natural length, the contraction and extension occur in a direction different from the direction of movement of the first member, thereby causing the side of the coil spring to contact the side surface portion.

[0009] According to the above configuration, when the first member approaches or moves away from the second member, the coil spring contracts from or expands to its natural length between the retaining portion of the first member and the retaining portion of the second member. These retaining portions are formed so that the contraction and expansion occur in a direction different from the direction of movement of the first member. As a result, the side surface of the coil spring contacts the side surface portion that faces the side of the coil spring and extends in the direction of movement of the first member, so that the vibration of the contracting and expanding coil spring as described above is suppressed by the side surface portion. Therefore, it is possible to suppress abnormal noise caused by the vibration of the expanding and contracting coil spring.

[0010] (Aspect 2) At least one of the retaining portion of the first member and the retaining portion of the second member has a variation portion formed therein that inclines the axial end of the coil spring relative to a plane perpendicular to the movement direction of the first member (embodiment 1).

[0011] According to the above configuration, due to a variation portion formed on at least one of the holding portion of the first member and the holding portion of the second member, the axial end of the coil spring is inclined with respect to a plane perpendicular to the movement direction of the first member. By inclining the axial end of the coil spring with respect to a plane perpendicular to the movement direction of the first member in this manner, the direction in which the coil spring contracts and expands differs from the direction in which the first member moves. As a result, the side of the contracting and expanding coil spring can be brought into contact with the side surface portion, and this contact can suppress vibration during expansion and contraction of the coil spring.

[0012] (Aspect 3) One of the retaining portion of the first member and the retaining portion of the second member has one end of the coil spring in the axial direction parallel to a plane perpendicular to the movement direction of the first member, and the other of the retaining portion of the first member and the retaining portion of the second member has a variation portion formed therein that inclines the other end of the coil spring in the axial direction relative to the plane (embodiment 1).

[0013] According to the above configuration, one of the holding portion of the first member and the holding portion of the second member has one end of the coil spring in the axial direction parallel to a plane perpendicular to the movement direction of the first member. Furthermore, the other of the holding portion of the first member and the holding portion of the second member has a variation portion that tilts the other end of the coil spring in the axial direction relative to the plane. This not only makes the direction in which the coil spring contracts and expands different from the movement direction of the first member, but also makes the coil spring more likely to bend in the axial direction. As a result, the coil spring is more likely to come into contact with the side portion when expanding or contracting.

[0014] (Aspect 4) The first member is a bearing portion provided on the box body of a console box, the second member is the box body, the bearing portion rotatably supports a rotating shaft provided on a lid that opens and closes an opening of the box body, and the coil spring biases the bearing portion toward a position where it protrudes from the box body and can support the rotating shaft. (Aspect 1) to (Aspect 3) are embodiments of a vehicle interior part.

[0015] According to the above configuration, the bearing portion protrudes from the box body due to the biasing force of the coil spring, thereby moving to a position where it rotatably supports the rotation shaft of the lid. At this time, the rotation shaft of the lid is rotatably supported by the bearing portion. The lid opens and closes the opening of the box body by rotating around the center line of the rotation shaft. Furthermore, the bearing portion moves against the biasing force of the coil spring, thereby moving away from the rotation shaft of the lid. At this time, the lid can be moved away from the opening by moving it from a position where it closes the opening of the box body to another position. When the bearing portion moves as described above, the coil spring contracts from or expands toward its natural length. As the side of the contracting and expanding coil spring contacts the side surface, vibration of the expanding and contracting coil spring is suppressed.

[0016] (Aspect 4) The first member is a pivot shaft provided on a lid that opens and closes the opening of the box body in the console box, the second member is the lid, the pivot shaft is rotatably supported by a bearing portion provided on the box body, and the coil spring biases the pivot shaft toward a position where it protrudes from the lid and can be supported by the bearing portion (Aspect 1) to (Aspect 3), a vehicle interior part described in any one of these.

[0017] According to the above configuration, the pivot shaft protrudes from the lid due to the biasing force of the coil spring, and moves to a position where it can be supported by the bearing portion of the box body. At this time, the pivot shaft of the lid is rotatably supported by the bearing portion. The lid opens and closes the opening of the box body by rotating around the center line of the pivot shaft. Furthermore, the pivot shaft moves against the biasing force of the coil spring, and is positioned away from the bearing portion of the box body. At this time, the lid can be removed from the opening by moving it from a position where it closes the opening of the box body to another position. When the pivot shaft moves as described above, the coil spring contracts from and expands toward its natural length. As the side of the contracting and expanding coil spring contacts the side surface in this manner, vibration of the expanding and contracting coil spring is suppressed.

[0019] [First embodiment] A first embodiment of a vehicle interior trim will be described below with reference to FIGS. The console box 11 shown in Fig. 1 is an interior component for a vehicle and forms part of a center console located between the driver's seat and the passenger seat inside the vehicle. The console box 11 includes a box body 13 attached to a housing 12 of the center console, and a lid 14 for opening and closing the opening of the box body 13. The box body 13 is formed in the shape of a rectangular parallelepiped that opens upward.

[0020] A support part 15 shown in FIG. 3 is attached to the upper end of the box body 13 shown in FIG. 2. The support part 15 is formed in a rectangular frame shape and is part of the box body 13. The support part 15 forms the opening at the upper end of the box body 13. The opening is opened and closed by rotating a rectangular plate-shaped lid 14 shown in FIG. 1. The lid 14 can also be removed from the opening by moving it from a position that closes the opening to another position. When the lid 14 is removed from the opening in this way, the opening is opened.

[0021] As shown in Figure 3, upwardly protruding support walls 16 are formed at the front and rear ends of the support portion 15 in the longitudinal direction of the vehicle. These support walls 16 extend in the width direction of the vehicle, i.e., in the left-right direction of the vehicle. The lid 14 can be placed between these support walls 16. Shim accommodating portions 17 are formed at opposing positions on these support walls 16. The opposing shim accommodating portions 17 are formed at both longitudinal ends of the support wall 16. Note that Figure 3 shows only one of the opposing shim accommodating portions 17.

[0022] After the coil spring 18 is inserted into the shim accommodating portion 17, the shim 19 is inserted. The shim 19 functions as a bearing portion provided on the support wall 16 of the support portion 15 in the box body 13. The shim 19 is used to rotatably support the lid 14. The shim 19 functioning as a bearing portion serves as a first member. Furthermore, the portion of the support wall 16 that corresponds to the bottom of the shim accommodating portion 17 serves as a second member.

[0023] <Details of Shim Receptacle 17 and Shim 19> As shown in Figures 4 and 5, the shim accommodating portion 17 has a cylindrical shape extending in the front-rear direction. An insertion hole 20 is formed in the bottom of the shim accommodating portion 17, and two locking holes 21 are formed on either side of the insertion hole 20. A rotation restricting groove 22 extending in the front-rear direction is formed in the inner peripheral surface of the shim accommodating portion 17. The shim 19 inserted into the shim accommodating portion 17 has a cylindrical shape. The coil spring 18 is disposed between the shim 19 and a portion of the support wall 16 corresponding to the bottom of the shim accommodating portion 17. The shim 19 has a shaft portion 23 that is inserted into the insertion hole 20 and two locking portions 24 that are inserted into the two locking holes 21. A rotation restricting protrusion 25 that is inserted into the rotation restricting groove 22 is formed in the outer peripheral surface of the shim 19.

[0024] The shim 19 is movable in the front-to-rear direction relative to the shim accommodating portion 17, i.e., in the direction of protruding from and retracting into the shim accommodating portion 17. The shim 19 is biased by the coil spring 18 in a direction away from the bottom of the shim accommodating portion 17. When the shim 19 moves as described above, the shaft portion 23, the locking portion 24, and the rotation restricting protrusion 25 of the shim 19 move in the front-to-rear direction relative to the insertion hole 20, the locking hole 21, and the rotation restricting groove 22 of the shim accommodating portion 17, respectively. The locking portion 24 of the shim 19 is locked into the locking hole 21 of the shim accommodating portion 17, thereby restricting removal of the locking portion 24 from the locking hole 21. This restriction on removal of the locking portion 24 from the locking hole 21 prevents the shim 19 from falling out of the shim accommodating portion 17. Furthermore, by inserting the rotation restricting protrusion 25 of the shim 19 into the rotation restricting groove 22 of the shim accommodating portion 17 , rotation of the shim 19 around the center line relative to the shim accommodating portion 17 is restricted.

[0025] An outer inclined surface 26 is formed at the upper end of the end face of the shim 19 in the direction of protrusion from the shim accommodating portion 17. The outer inclined surface 26 is inclined downward so that it is positioned more forward in the direction of protrusion of the shim 19 from the shim accommodating portion 17. An accommodating recess 27 is formed in the center of the end face of the shim 19 in the direction of protrusion from the shim accommodating portion 17. A reference surface 28 and an inner inclined surface 29 are formed inside this accommodating recess 27. The reference surface 28 is perpendicular to the center line of the shim 19. The inner inclined surface 29 is positioned closer to the center of the support wall 16 in the longitudinal direction than the reference surface 28 and is connected to the reference surface 28. The inner inclined surface 29 is inclined toward the center of the support wall 16 in the longitudinal direction so that it is positioned more forward in the direction of protrusion of the shim 19 from the shim accommodating portion 17.

[0026] <Details of Lid 14> As shown in FIG. 6 , the lid 14 includes two support plates 30 spaced apart in the longitudinal direction of the vehicle. These support plates 30 extend in the width direction of the vehicle, i.e., in the left-right direction of the vehicle. A long hole 30a is formed at each of both longitudinal ends of the support plate 30. The long hole 30a is formed to extend along the longitudinal direction of the support plate 30. The lid 14 includes two rotating shafts 31 extending in the longitudinal direction therein. One rotating shaft 31 is located corresponding to one longitudinal end of the support plate 30, and the other rotating shaft 31 is located corresponding to the other longitudinal end of the support plate 30. The ends of the rotating shafts 31 pass through the corresponding long holes 30a in the support plate 30.

[0027] A pinion gear 32 is formed on the rotating shaft 31 at a position closer to the center than either end. The pinion gear 32 is meshed with a rack gear 33 formed inside the lid 14. The rack gear 33 extends in the same direction as the support plate 30. The rotating shaft 31 can move in the longitudinal direction of the support plate 30 by an amount corresponding to the length of the elongated hole 30a in the support plate 30 through the rolling of the pinion gear 32 along the rack gear 33. The end of the rotating shaft 31 protruding from the support plate 30 of the lid 14 is inserted into the accommodation recess 27 of the shim 19 shown in FIG. 5. As a result, the end of the rotating shaft 31 is rotatably supported by the shim 19.

[0028] 4 and 5, the shim 19 is biased by the coil spring 18 in a direction that causes it to protrude from the shim accommodating portion 17 of the support wall 16. The shim 19 rotatably supports the end of the pivot shaft 31 in the lid 14 while protruding from the shim accommodating portion 17 due to the biasing force of the coil spring 18. On the other hand, when the shim 19 is retracted into the shim accommodating portion 17 against the biasing force of the coil spring 18, the shim 19 separates from the end of the pivot shaft 31 in the lid 14, causing the end to be extracted from the accommodating recess 27 for the shim 19.

[0029] When both ends of one of the two pivot shafts 31 of the lid 14 shown in FIG. 6 are removed from the accommodation recess 27 of the shim 19 as described above, the lid 14 becomes able to rotate around the center line of the other pivot shaft 31. This rotation of the lid 14 opens and closes the opening of the support portion 15 of the box body 13 shown in FIG. 3. Furthermore, when both ends of the two pivot shafts 31 of the lid 14 shown in FIG. 6 are removed from the accommodation recess 27 of the shim 19 as described above, the lid 14 becomes able to move from the position where it closes the opening to another position. This movement of the lid 14 opens the opening.

[0030] 4 and 5 , the movement of the shim 19 against the biasing force of the coil spring 18 is achieved by pressing the end of the pivot shaft 31 against the outer inclined surface 26 and the inner inclined surface 29 of the shim 19. More specifically, when the end of the pivot shaft 31 is inserted into the accommodation recess 27 of the shim 19, moving the pivot shaft 31 in a direction toward the center of the longitudinal direction of the support wall 16 causes the end of the pivot shaft 31 to be pressed against the inner inclined surface 29 within the accommodation recess 27. This causes the shim 19 to sink into the shim accommodation portion 17 against the biasing force of the coil spring 18. As a result, the end of the pivot shaft 31 is removed from the accommodation recess 27 of the shim 19.

[0031] Furthermore, when the end of the pivot shaft 31 is pulled out of the accommodation recess 27 of the shim 19, the end of the pivot shaft 31 is moved above the shim 19 protruding from the shim accommodation portion 17, and then the pivot shaft 31 is moved downward. This movement of the pivot shaft 31 causes the end of the pivot shaft 31 to be pressed against the outer inclined surface 26 of the shim 19. As a result, the shim 19 is sunk into the shim accommodation portion 17 against the biasing force of the coil spring 18, and the end of the pivot shaft 31 is inserted into the accommodation recess 27 of the shim 19.

[0032] 6 and 7, the lid 14 is provided with an operating mechanism 34 that moves the pivot shaft 31 from the position where its end is inserted into the accommodation recess 27 of the shim 19 toward the center in the longitudinal direction of the support plate 30. The operating mechanism 34 includes an operating base 35, an operating part 36, and a spring 37.

[0033] The operation base 35 is fixed inside the lid 14. The operation unit 36 ​​is arranged on top of the operation unit 36 ​​so that the operation unit 36 ​​can slide in the width direction of the vehicle, i.e., in the left-right direction of the vehicle. The operation unit 36 ​​is formed with an arc-shaped bearing recess 38 that opens upward. The rotating shaft 31 is rotatably supported by this bearing recess 38. The spring 37 is arranged between a spring bearing portion 39 formed on the operation base 35 and a spring bearing portion 40 formed on the operation unit 36. The spring 37 biases the operation unit 36 ​​and the rotating shaft 31 in a direction along the longitudinal direction of the support plate 30 shown in FIG. 6, toward the end of the longitudinal direction.

[0034] The operating part 36 is exposed from both sides of the lid 14 in the longitudinal direction of the support plate 30 by the biasing force of the spring 37. At this time, the rotating shaft 31 is held in a position where its end is inserted into the accommodation recess 27 of the shim 19. In other words, the rotating shaft 31 is held in the above position by the biasing force of the coil spring 18. In this state, when the operating part 36 is pushed toward the center of the support plate 30 in the longitudinal direction, the operating part 36 and the rotating shaft 31 move toward the center of the support plate 30 in the longitudinal direction against the biasing force of the spring 37.

[0035] <Movement of the lid 14 relative to the opening of the box body 13> 8 and 9 show a state in which the end of the pivot shaft 31 in the lid 14 is inserted into the accommodation recess 27 of the shim 19, and Fig. 10 shows a state in which the end of the pivot shaft 31 is removed from the accommodation recess 27. Fig. 11 shows an enlarged cross section of a portion of the lid 14 near the support plate 30, and Fig. 12 shows an enlarged cross section of a portion of the lid 14 near the operating mechanism 34.

[0036] 8 and 9, when the lid 14 closes the opening of the box body 13, the end of the pivot shaft 31 in the lid 14 is inserted into the accommodating recess 27 of the shim 19. At this time, the urging force of the coil spring 18 causes the shim 19 to protrude from the shim accommodating recess 17 of the support wall 16 of the box body 13. As described above, with the end of the pivot shaft 31 inserted into the accommodating recess 27 of the shim 19, the lid 14 is locked in a position that closes the opening.

[0037] 10 , when the operating portion 36 of the operating mechanism 34 is pressed against the biasing force of the spring 37, the rotating shaft 31 moves in a direction toward the center of the support plate 30 in the longitudinal direction, and the end of the rotating shaft 31 is pressed against the inner inclined surface 29 of the shim 19. This causes the shim 19 to sink into the shim accommodating portion 17 against the biasing force of the coil spring 18. As a result, the end of the rotating shaft 31 is removed from the accommodating recess 27 of the shim 19. When the end of the rotating shaft 31 is removed from the accommodating recess 27 of the shim 19 in this way, the above-mentioned lock of the lid 14 is released.

[0038] The lock on the lid 14 can be released individually at the locations on the lid 14 that correspond to the two rotation shafts 31. When the lock on the lid 14 is released, the location on the lid 14 that corresponds to the two rotation shafts 31 and that has been released can be lifted upward from the opening of the box body 13.

[0039] When only one of the two portions of the lid 14 corresponding to the pivot shafts 31 is unlocked, the lid 14 can be rotated by lifting the unlocked portion upward from the opening of the box body 13. Specifically, the lid 14 rotates around the center line of the pivot shaft 31 at the portion where the lock is not released. The lid 14 then opens the opening of the box body 13 by moving from the position shown by the solid line in Figures 11 and 12 as shown by the two-dot chain line.

[0040] Furthermore, when the locks are released at both of the locations on the lid 14 corresponding to the two pivot shafts 31, the entire lid 14 can be moved from the opening by lifting both of these locations upward from the opening of the box body 13. That is, in this case, the lid 14 can be moved from the location that is blocking the opening of the box body 13 to another location. When the lid 14 is moved in this way, the opening of the box body 13 is also opened.

[0041] When the lid 14 is used to close the opening of the box body 13, the portion of the lid 14 corresponding to the pivot shaft 31 is positioned above the opposing shim 19 of the support portion 15 of the box body 13 shown in FIG. 8. Furthermore, the end of the pivot shaft 31 is aligned with the position above the opposing shim 19. In this state, when the portion of the lid 14 corresponding to the pivot shaft 31 is moved downward, the end of the pivot shaft 31 is pressed against the outer inclined surface 26 of the shim 19 as shown in FIG. 13. As a result, the shim 19 is sunk into the shim accommodating portion 17 against the biasing force of the coil spring 18.

[0042] When the end of the pivot shaft 31 moving downward is positioned corresponding to the accommodation recess 27 of the shim 19, the shim 19 protrudes from the shim accommodation portion 17 due to the biasing force of the coil spring 18. As a result, the end of the pivot shaft 31 is inserted into the accommodation recess 27 of the shim 19, as shown in FIG. 14 . As a result, the portion of the lid 14 corresponding to the pivot shaft 31 is locked to the box body 13. This locking can be performed individually at the portions of the lid 14 corresponding to the two pivot shafts 31. Then, by locking both of the portions of the lid 14 corresponding to the two pivot shafts 31, the lid 14 is locked in a position that closes the opening of the box body 13.

[0043] When the shim 19 is moved relative to the shim housing 17 of the support wall 16 of the box body 13, the coil spring 18 contracts from and expands to its natural length. When the coil spring 18 contracts and expands in this manner, the coil spring 18 vibrates finely, generating abnormal noise. To prevent this from happening, the shim 19 and the shim housing 17 in the console box 11 have a structure that suppresses the generation of the abnormal noise.

[0044] <Structure of the shim 19 and the shim receiving portion 17 for suppressing the generation of abnormal noise> As shown in Fig. 15, a coil spring 18 is disposed between the shim 19 and the support wall 16 of the box body 13 so as to extend along the center line of the shim 19. As shown in Figs. 15 and 16, a rib 55 that protrudes toward the center line of the shim 19 is formed on the inner peripheral surface of the shim 19. The rib 55 is located at the lower end of the inner peripheral surface of the shim 19 in Figs. 15 and 16. The rib 55 faces the side of the coil spring 18 and serves as a side surface that extends in the direction of movement of the shim 19.

[0045] Instead of forming the rib 55 on the inner peripheral surface of the shim 19, the diameter of the inner peripheral surface of the shim 19 may be reduced so that the inner peripheral surface of the shim 19 coincides with the end face of the protruding direction of the rib 55. In this case, the inner peripheral surface of the shim 19 serves as the side surface portion.

[0046] 15 , the shim 19 has a retaining portion 52 with which one axial end of the coil spring 18 comes into contact. The retaining portion 52 is located at a portion of the shim 19 facing the support wall 16 of the box body 13, more specifically, at a portion of the support wall 16 facing the bottom of the shim accommodating portion 17. The support wall 16 of the box body 13 has a retaining portion 53 with which one axial end of the coil spring 18 comes into contact. The retaining portion 53 is located at a portion of the support wall 16 facing the shim 19, more specifically, at a portion of the support wall 16 corresponding to the bottom of the shim accommodating portion 17. The retaining portions 52, 53 are formed so that when the shim 19 moves into or out of the shim accommodating portion 17 of the support wall 16, the coil spring 18 contracts and expands in a direction different from the direction of movement of the shim 19.

[0047] That is, the retaining portion 53 of the support wall 16 is formed so that one axial end of the coil spring 18 that contacts the retaining portion 53 is parallel to a plane perpendicular to the direction of movement of the shim 19, i.e., the direction in which the center line of the shim 19 extends. Meanwhile, the retaining portion 52 of the shim 19 is formed with a deviated portion 56 with which the other axial end of the coil spring 18 contacts. The deviated portion 56 tilts the other axial end of the coil spring 18 with respect to the plane perpendicular to the direction of movement of the shim 19, i.e., the direction in which the center line of the shim 19 extends. The deviated portion 56 is formed by recessing the lower portion of the retaining portion 52 of the shim 19 to a position farther from the retaining portion 52 of the support wall 16 than the upper portion. This causes the other axial end of the coil spring 18 to be tilted as described above.

[0048] Next, the effects of the console box 11 as a vehicle interior part in this embodiment will be described. (1-1) The shim 19 protrudes from the shim accommodating portion 17 of the support wall 16 of the box body 13 due to the biasing force of the coil spring 18, and moves to a position where it rotatably supports the pivot shaft 31 of the lid 14. At this time, the pivot shaft 31 of the lid 14 is rotatably supported by the accommodating recess 27 of the shim 19. The lid 14 opens and closes the opening of the box body 13 by rotating around the center line of the pivot shaft 31. Furthermore, the shim 19 moves to retract into the shim accommodating portion 17 against the biasing force of the coil spring 18, and is positioned away from the pivot shaft 31 of the lid 14. At this time, the lid 14 can be moved away from the opening by moving it from the position where it blocks the opening of the box body 13 to another position.

[0049] When the shim 19 moves as described above, the shim 19 approaches or moves away from a portion of the support wall 16 that corresponds to the bottom of the shim accommodating portion 17, causing the coil spring 18 to contract and expand between the retaining portion 52 of the shim 19 and the retaining portion 53 of the support wall 16. These retaining portions 52, 53 are formed so that the coil spring 18 contracts and expands in a direction different from the direction of movement of the shim 19. As a result, the side of the coil spring 18 comes into contact with the side surface portion that faces the side of the coil spring 18 and extends in the direction of movement of the shim 19. As a result, the vibration of the expanding and contracting coil spring 18 is suppressed by the side surface portion. Therefore, it is possible to suppress the generation of abnormal noise due to the vibration of the expanding and contracting coil spring 18.

[0050] (1-2) The coil spring 18 can be contracted and extended in a direction different from the direction of movement of the shim 19 by forming the retaining portion 52 of the shim 19 and the retaining portion 53 of the support wall 16 as follows. That is, the retaining portion 53 of the support wall 16 is formed so that one axial end of the coil spring 18 that contacts the retaining portion 53 is parallel to a plane perpendicular to the direction of movement of the shim 19. Meanwhile, the retaining portion 52 of the shim 19 has a deviating portion 56 that tilts the other axial end of the coil spring 18 relative to the plane. By forming the retaining portions 52 and 53 in this manner, when the coil spring 18 contracts and extends, not only does the contraction and extension occur in a direction different from the direction of movement of the shim 19, but the coil spring 18 also tends to bend in the direction of expansion and contraction. As a result, the coil spring 18 tends to come into contact with the side portion of the shim 19 when expanding or contracting.

[0051] It is considered that the inclination of the end portion in the axial direction of the coil spring 18 is set to an angle of about 20° with respect to the surface. The inclination angle is preferably set to a value within a predetermined range determined in advance by experiments or the like, which is greater than 0° and equal to or less than 20°.

[0052] (1-3) A rib 55 is formed on the inner peripheral surface of the shim 19 as the side surface portion. This rib 55 is located at the lower end of the inner peripheral surface of the shim 19, in other words, at a location corresponding to the variation portion 56 of the shim 19. The variation portion 56 is formed by recessing the lower portion of the upper and lower portions of the retaining portion 52 of the shim 19 to a position farther from the retaining portion 53 of the support wall 16 than the upper portion. This makes it easier for the coil spring 18 to curve so as to bulge toward the rib 55 when contracting and expanding. As a result, the coil spring 18 is more likely to come into contact with the rib 55 when expanding or contracting.

[0053] [Second embodiment] Next, a second embodiment of a vehicle interior trim will be described with reference to FIGS. In the console box 11 of this embodiment, as shown in FIG. 17, the rotating shaft 31 is divided into a first shaft portion 41 and a second shaft portion 42 extending on the same axis, and a coil spring 43 is arranged between the first shaft portion 41 and the second shaft portion 42.

[0054] A bearing 44 into which the first shaft 41 is inserted is formed in one support wall 16 of the support portion 15 of the box body 13. A bearing 45 into which the second shaft 42 is inserted is formed in the other support wall 16 of the support portion 15 of the box body 13. The first shaft 41 and the second shaft 42 are inserted into the bearings 44, 45 of the support wall 16 by being biased in directions away from each other by a coil spring 43. The bearing 44 rotatably supports the first shaft 41. The bearing 45 rotatably supports the second shaft 42. As shown in FIG. 18 , the first shaft 41 and the second shaft 42 of the rotating shaft 31 are formed with through holes 46, 47 extending in the vertical direction, i.e., in a direction perpendicular to the plane of the paper in FIG. 18 .

[0055] The operating mechanism 34 of the lid 14 is capable of moving the pivot shaft 31. The operating portion 36 of the operating mechanism 34 includes pins 48, 49 that pass through the through holes 46, 47 of the first shaft portion 41 and the second shaft portion 42. The inner surfaces of the through holes 46, 47 are formed with inclined surfaces 50, 51 that come into contact with the pins 48, 49. The inclined surfaces 50, 51 are pressed against the pins 48, 49 by the biasing force of the coil spring 43. The inclined surface 50 is inclined so as to move away from the second shaft portion 42 as it moves toward the center of the lid 14 in the vehicle width direction, i.e., toward the bottom in Figure 18. The inclined surface 51 is inclined so as to move away from the first shaft portion 41 as it moves toward the center of the lid 14 in the vehicle width direction, i.e., toward the bottom in Figure 18.

[0056] The operating unit 36 ​​is biased toward a position exposed from the lid 14 by a spring 37 between the operating unit 36 ​​and the operating base 35 of the operating mechanism 34. When the operating unit 36 ​​is pushed in a direction to retract into the lid 14, the operating unit 36 ​​moves against the biasing force of the spring 37. As the operating unit 36 ​​moves in this manner, the pins 48, 49 press the inclined surfaces 50, 51 in a direction to bring the first shaft portion 41 and the second shaft portion 42 closer to each other. As a result, as shown in FIG. 17 , the first shaft portion 41 and the second shaft portion 42 are extracted from the bearing portions 44, 45. The first shaft portion 41 and the second shaft portion 42 are inserted into the bearing portions 44, 45 by reversing the above-described procedure.

[0057] When the first shaft portion 41 is inserted into or extracted from the bearing portion 44, the first shaft portion 41 functions as a first member. At this time, the second shaft portion 42 serves as a second member that is part of the lid 14. Furthermore, when the second shaft portion 42 is inserted into or extracted from the bearing portion 45, the second shaft portion 42 functions as a first member. At this time, the first shaft portion 41 serves as a second member that is part of the lid 14. As shown in FIG. 18 , the portion of the first shaft portion 41 facing the second shaft portion 42 forms a retaining portion 52 with which one end of the coil spring 43 in the axial direction contacts. The portion of the second shaft portion 42 facing the first shaft portion 41 forms a retaining portion 53 with which the other end of the coil spring 43 in the axial direction contacts.

[0058] The retaining portions 52, 53 are formed so that the coil spring 43 contracts and expands in a direction different from the direction of movement of the first and second shaft portions 41, 42 when the first and second shaft portions 41, 42 are inserted into or extracted from the bearing portions 44, 45. That is, the retaining portion 53 of the second shaft portion 42 is formed so that one axial end of the coil spring 43 that contacts the retaining portion 53 is parallel to a plane perpendicular to the direction in which the center lines of the first and second shaft portions 41, 42 extend. On the other hand, the retaining portion 52 of the first shaft portion 41 is formed so that the other axial end of the coil spring 43 that contacts the retaining portion 52 is inclined with respect to the plane. The inclination of the end with respect to the plane is such that the end is positioned closer to the tip of the first shaft portion 41 in the protruding direction as it extends downward.

[0059] A cylindrical portion 54 that surrounds the retaining portion 52 and protrudes toward the second shaft portion 42 is formed on the first shaft portion 41 at a location facing the second shaft portion 42. A rib 55 that protrudes toward the center line of the cylindrical portion 54 is formed on the lower end of the inner circumferential surface of the cylindrical portion 54. The rib 55 faces the side of the coil spring 43 and serves as a side portion that extends in the direction of movement of the first shaft portion 41 and the second shaft portion 42.

[0060] Instead of forming the ribs 55 on the inner peripheral surface of the cylindrical portion 54, the diameter of the inner peripheral surface of the cylindrical portion 54 may be reduced so that the inner peripheral surface of the cylindrical portion 54 coincides with the end face in the protruding direction of the ribs 55. In this case, the inner peripheral surface of the cylindrical portion 54 serves as the side surface portion.

[0061] According to this embodiment, the following effects can be obtained. (2-1) The first shaft portion 41 and the second shaft portion 42 of the rotating shaft 31 protrude from the lid 14 due to the biasing force of the coil spring 43, and move to a position where they can be supported by the bearing portions 44, 45 of the support wall 16 of the box body 13. At this time, the first shaft portion 41 and the second shaft portion 42 of the rotating shaft 31 are rotatably supported by the bearing portions 44, 45. The lid 14 opens and closes the opening of the box body 13 by rotating about the center line of the first shaft portion 41 and the second shaft portion 42 of the rotating shaft 31. Furthermore, the first shaft portion 41 and the second shaft portion 42 of the rotating shaft 31 move against the biasing force of the coil spring 43, and are positioned away from the bearing portions 44, 45. At this time, the lid 14 can be removed from the opening of the box body 13 by moving it from the position where it closes the opening to another position. When the first shaft portion 41 and the second shaft portion 42 of the rotating shaft 31 move as described above, the coil spring 43 contracts and expands accordingly. The side portions of the contracting and expanding coil spring 43 come into contact with the side surface portions, thereby suppressing vibration of the expanding and contracting coil spring 43.

[0062] (2-2) Contracting and extending the coil spring 43 in a direction different from the moving direction of the first shaft portion 41 and the second shaft portion 42 is achieved by forming the holding portion 52 of the first shaft portion 41 and the holding portion 53 of the second shaft portion 42 as follows. That is, the holding portion 53 of the second shaft portion 42 is formed so that one axial end of the coil spring 43 that contacts the holding portion 53 is parallel to a plane perpendicular to the center line of the first shaft portion 41 and the second shaft portion 42. On the other hand, the holding portion 52 of the first shaft portion 41 is formed so that the other axial end of the coil spring 43 that contacts the holding portion 53 is inclined with respect to the plane. The inclination of the end with respect to the plane is such that the end is positioned closer to the tip of the first shaft portion 41 in the protruding direction as it goes downward. By forming the holding portions 52, 53 in this manner, when the coil spring 43 contracts and expands, not only does the direction of contraction and expansion differ from the movement direction of the first shaft portion 41 and the second shaft portion 42, but the coil spring 43 also tends to bend in the axial direction. As a result, the coil spring 43 tends to come into contact with the side surface portion when expanding or contracting.

[0063] (2-3) A rib 55 is formed as the side surface on the inner circumferential surface of the cylindrical portion 54 of the first shaft portion 41. This rib 55 is located at the lower end of the inner circumferential surface of the cylindrical portion 54, in other words, at a location corresponding to the lower end of the holding portion 52 of the first shaft portion 41. Since the holding portion 52 inclines the end of the coil spring 43 that contacts the holding portion 52 as described above, the coil spring 43 tends to curve so as to bulge toward the rib 55 when contracting and expanding. As a result, the coil spring 43 tends to come into contact with the rib 55 when expanding or contracting.

[0064] [Other embodiments] The above-described embodiments can be modified as follows, for example: The above-described embodiments and the following modifications can be combined with each other within the scope of technical compatibility.

[0065] In the first embodiment, the positions of the rib 55 and the variation portion 56 may be changed in the circumferential direction of the shim 19 as appropriate. In the first embodiment, instead of or in addition to forming the ribs 55 on the inner peripheral surface of the shim 19, ribs may be formed as side surfaces on the inner peripheral surface of the shim accommodating portion 17. Furthermore, the ribs 55 on the inner peripheral surface of the shim 19 and the ribs on the inner peripheral surface of the shim accommodating portion 17 may be omitted, and side surfaces may be provided that are separate from the shim 19 and the shim accommodating portion 17.

[0066] In the first embodiment, contracting and expanding the coil spring 18 in a direction different from the movement direction of the shim 19 may be achieved by forming the retaining portion 52 of the shim 19 and the retaining portion 53 of the support wall 16 as follows. That is, the retaining portion 52 of the shim 19 is formed so that one axial end of the coil spring 18 in contact with the retaining portion 52 is parallel to a plane perpendicular to the movement direction of the shim 19. Meanwhile, the retaining portion 53 of the support wall 16 is formed with a variation portion 56 that tilts the other axial end of the coil spring 18 in contact with the retaining portion 53 with respect to the plane. Also, both the retaining portion 52 and the retaining portion 53 may be formed with a variation portion 56 that tilts the ends of the coil spring 18 in contact with the retaining portions 52, 53 with respect to the plane.

[0067] In the first embodiment, one of the two pivot shafts 31 on the lid 14 may be omitted, and the shim 19, shim accommodating section 17, coil spring 18, operating mechanism 34, etc. corresponding to the omitted pivot shaft 31 may also be omitted, thereby making the lid 14 a one-sided opening type.

[0068] In the second embodiment, the position of the rib 55 may be changed as appropriate in the circumferential direction of the cylindrical portion 54, and the inclination direction of the holding portion 52 may be changed accordingly. In the second embodiment, instead of forming the cylindrical portion 54 and the ribs 55 on the first shaft portion 41, or in addition to the cylindrical portion 54 and the ribs 55, the second shaft portion 42 may be formed with a cylindrical portion and ribs as side portions. Also, the ribs 55 on the first shaft portion 41 and the ribs on the second shaft portion 42 may be omitted, and side portions separate from the first shaft portion 41 and the second shaft portion 42 may be provided.

[0069] In the second embodiment, contracting and expanding the coil spring 43 in a direction different from the movement direction of the first shaft portion 41 and the second shaft portion 42 may be achieved by forming the retaining portion 52 of the first shaft portion 41 and the retaining portion 53 of the second shaft portion 42 as follows. That is, the retaining portion 52 of the first shaft portion 41 is formed so that one axial end of the coil spring 18 that contacts the retaining portion 52 is parallel to a plane perpendicular to the movement direction of the first shaft portion 41 and the second shaft portion 42. On the other hand, the retaining portion 53 of the second shaft portion 42 is formed so that the other axial end of the coil spring 18 that contacts the retaining portion 53 is inclined with respect to the plane. Also, both the retaining portion 52 and the retaining portion 53 may be formed so that the end of the coil spring 18 that contacts the retaining portion 52, 53 is inclined with respect to the plane.

[0070] In the second embodiment, one of the two pivot shafts 31 on the lid 14 may be omitted, and the operating mechanism 34 corresponding to the omitted pivot shaft 31 may also be omitted, so that the lid 14 opens in one direction.

[0071] The present invention may be applied to a vehicle interior part other than the console box 11, that is, a vehicle interior part including a first member, a second member, and a coil spring. [Explanation of symbols]
