[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-157788 Summary of the Invention [Problem to be solved by the invention]

[0004] The mounting structure described in Patent Document 1 is configured so that the vehicle interior material is sandwiched between the tip of the protrusion of the functional component and the back surface (the exterior surface of the vehicle cabin) of the functional component body. Therefore, the back surface of the functional component body comes into contact with the decorative surface of the vehicle interior material, which may cause scratches or other damage to the decorative surface. The document also describes a configuration that prevents such scratches by providing a soft material on the exterior surface of the functional component, but if the functional component has multiple protrusions, this creates a problem of increasing the number of components.

[0005] The present invention has been made in consideration of such circumstances, and its object is to provide a mounting structure for functional components that can prevent scratches on the design surface of vehicle interior materials without using a separate part such as a soft material. [Means for solving the problem]

[0006] In order to solve the above problems, the functional component mounting structure of the present invention comprises: A mounting structure for detachably mounting a functional component to an interior side of a vehicle interior material, comprising: the functional component includes a functional component main body and a latched portion protruding from the functional component main body, The vehicle interior material includes a generally plate-shaped interior material main body and a locking portion that locks the locked portion of the functional component, The locking portion has a through hole including a plurality of elongated hole portions formed through the interior material main body portion and extending radially, and a back wall portion provided at a distance from the back surface of the interior material main body portion toward the outside of the vehicle compartment and covering the through hole, the engaged portion has a shaft portion that protrudes from the functional component main body portion toward the vehicle interior material, and an extension portion that is formed at the tip of the shaft portion and extends in a direction intersecting the axis of the shaft portion, and the shape of the engaged portion when viewed from the direction in which the axis extends is configured to fit inside the through hole, the functional component is configured to be attached to the vehicle interior material by inserting the engaging portion into the through hole and moving it along one of the plurality of elongated hole portions until a tip end of the engaging portion engages with a hole edge of the elongated hole portion, The rear wall portion is formed with a bulging portion that bulges toward the inside of the vehicle compartment, The engaging portion is characterized in that the tip of the engaged portion is sandwiched between the bulging portion and the outer surface of the interior material main body portion, thereby engaging the engaged portion.

[0007] The mounting structure for a functional component disclosed herein is configured to allow the functional component to be mounted to a vehicle interior material by sliding the functional component in one direction. With this mounting structure, when a user inserts the engaging portion into the through-hole and slides the functional component, the engaging portion contacts the bulging portion of the engaging portion and is pressed toward the interior of the vehicle, with the leading end of the engaging portion being clamped between the bulging portion and the rear surface of the interior material body. In other words, when the functional component is slid, the functional component body is moved in a direction away from the interior surface (design surface) of the interior material body of the vehicle interior material, preventing contact between the functional component body and the interior material body and preventing scratches and other damage to the vehicle interior material. Furthermore, there is no need to provide a soft material between the rear surface of the functional component body and the interior material body, thereby reducing the number of components.

[0008] In the mounting structure disclosed in the present application, the rear wall portion constituting the locking portion may be integrally molded with the interior material main body portion for each through hole, or may be formed by covering two or more of the multiple through holes together from the rear side with a separate plate-shaped member.

[0009] In the above configuration, the through hole has three of the long hole portions, the engaging portion has two of the extension portions, and the functional part can be inserted into the through hole using two of the three long hole portions, which are the insertion long hole portions, and can be moved along the remaining long hole portion, which is the engaging long hole portion.

[0010] In this mounting structure, the through hole is generally Y-shaped and the locked portion is generally V-shaped. For example, the functional component can be configured to slide downward, making it relatively easy to attach and detach the functional component. When molding the locked portion of the functional component by injection molding, if the tip of the locked portion has a ring-shaped protruding shape, as in the prior art document, it cannot be molded using a one-way sliding mold. However, the functional component in this configuration can be molded using a one-way sliding mold. Furthermore, the through hole and the rear wall portion of the vehicle interior material have the same Y-shape, and the rear wall portion prevents the exterior of the vehicle interior material from being seen through the through hole.

[0011] In the above-described configuration, the bulging portion may be formed at a position on the outer side of the vehicle cabin of the elongated locking hole in the rear wall portion.

[0012] In this mounting structure, the position of the bulge is specified relative to the Y-shaped rear wall portion. This mounting structure can reliably clamp the locked part between the hole edge of the locking slot and the bulge that bulges toward the locking slot.

[0013] In the above configuration, the engaging portion is molded integrally with the interior material main body portion, and has a plurality of upright portions that stand upright from the hole edge portions at the tip of each of the plurality of long hole portions toward the outside of the vehicle cabin, and the back wall portion can be molded integrally with the interior material main body portion and the plurality of upright portions, and can be configured to be a plate-like portion having the same shape as the through hole, which connects the plurality of upright portions.

[0014] In this mounting structure, the rear wall can be configured to elastically deform when the tip of the locked portion enters between the bulge and the interior material main body. In other words, the elastic force of the rear wall can press the tip of the locked portion against the back surface of the interior material main body, allowing the locking portion to more reliably lock the locked portion. Furthermore, in this mounting structure, by making the rear wall of the vehicle interior material slightly smaller in shape than the through hole, the interior material main body and the locking portion can be molded integrally by two-sided injection molding.

[0015] In the above configuration, the extension portion has a convex portion that protrudes toward the inside of the vehicle cabin, and the interior material main body portion has a concave portion on its outer surface outside the vehicle cabin, and the mounting structure can be configured so that the convex portion fits into the concave portion when the tip of the engaging portion is sandwiched between the bulge portion and the outer surface of the vehicle cabin of the interior material main body portion.

[0016] With this mounting structure, when the functional part is slid, the convex part of the engaging part fits into the recess of the interior material main body part. Therefore, when the engaging part is engaged with the engaging part, the engaging part is prevented from returning to the insertion position due to vehicle vibrations, etc., and it is possible to avoid the functional part coming off the vehicle interior material. [Effects of the Invention]

[0017] According to the present invention, it is possible to provide a mounting structure for a functional component that can prevent damage to the design surface of a vehicle interior material without using a separate component such as a soft material. [Brief explanation of the drawings]

[0019] A door trim 10 according to an embodiment of the present invention will be described with reference to Figs. 1 to 18. The door trim 10 of this embodiment is attached to the interior side of a door panel of a side door of a vehicle, forming a wall surface of the passenger compartment. The door trim 10 in Fig. 1 forms the right side door of the vehicle, but the left side door also has a door trim of a similar configuration. Note that in some of the drawings, directions are indicated using the symbols Fr, Rr, IN, OUT, U, and D, which respectively represent the front side, rear side, interior side (left side), exterior side (right side), upper side, and lower side of the vehicle.

[0020] <Composition of vehicle interior materials> As shown in FIG. 1, the door trim 10 of this embodiment is composed of a trim board (vehicle interior material) 12, which is the main board material that constitutes the door trim 10, and multiple functional parts that are detachable from the trim board 12, including a door pocket 14, a drink holder 16, a hook 18, and a cap 20.

[0021] The trim board 12 has an armrest 12A, and a recess 22 recessed toward the outside of the vehicle cabin (vehicle compartment) is formed below the armrest 12A. A bottom surface portion 22A, which forms the bottom surface of the recess 22, becomes a flat plate-like portion that stands upright in the vertical direction when installed in the vehicle. The bottom surface portion 22A, which is the main body of the interior material, is provided with a plurality of mounting portions 24 for mounting the functional components 14, 16, 18, and 20.

[0022] As shown in FIGS. 2 to 4, the mounting portion 24 mainly comprises a through hole 30 formed through the bottom surface portion 22A. The through hole 30 is composed of a central circular hole portion 32 and multiple (three in this embodiment) elongated hole portions 34A, 34B extending radially from the circular hole portion 32. The multiple elongated hole portions 34A, 34B are formed on the edge of the circular hole portion 32 and communicate with the circular hole portion 32. The multiple elongated hole portions 34A, 34B are also arranged radially at equal angular intervals (120° intervals) around the circular hole portion 32. Note that only a small portion of the edge of the round hole portion 32 exists as the edge of the through hole 30, and the shape of the through hole 30 is generally Y-shaped. 2 and 4, the width W1 of the lower oblong hole 34A, which extends downward among the plurality of oblong holes, is larger than the width W2 of the upper oblong hole 34B, which are the other two oblong holes. In this embodiment, W2 is about 6 mm, while W1 is about 8 mm.

[0023] 3, the mounting portion 24 is provided with protruding portions 40 formed integrally with the bottom surface 22A on the back surface (exterior surface) of the trim board 12, more specifically, on the back surface of the bottom surface 22A, in a manner that protrudes toward the exterior in correspondence with each through-hole 30. The protruding portions 40 generally have an upright portion 42, a connecting wall portion 44, and a rear wall portion 46.

[0024] Three upright portions 42 are provided corresponding to the elongated hole portions 34A, 34B of the through hole 30, and are portions that stand upright from the hole edge portions on the tip side (outer side in the radial direction) of the elongated hole portions 34A, 34B toward the outside of the room. The connecting wall portion 44 is a wall portion that stands upright toward the outside of the room between the three upright portions 42, and connects the side walls of the upright portions 42 together in a generally arc shape. With this configuration, the three upright portions 42 and the three connecting wall portions 44 form a generally annular upright wall portion 48 that surrounds the through hole 30.

[0025] 4, the upright portion 42 has a shape including a tip upright portion 42A that surrounds the tip of the hole edge portion of the elongated hole portions 34A, 34B and extends in a generally arc shape centered on the round hole portion 32, and a side upright portion 42B that extends radially from one end of the tip upright portion 42A toward the round hole portion 32. Note that the side upright portion 42B is provided to the right of the tip upright portion 42A in the circumferential direction when viewed from outside the vehicle cabin as shown in FIG.

[0026] 4, each of the three connecting wall portions 44 has two protrusions 44A, 44B provided on the inner peripheral surface thereof, spaced apart in the circumferential direction, that protrude toward the round hole portion 32. The first protrusion 44A protrudes less than the second protrusion 44B.

[0027] The rear wall portion 46 is a plate-like portion parallel to the bottom surface portion 22A and located away from the bottom surface portion 22A toward the exterior side of the room. The rear wall portion 46 has a generally Y-shape similar to the through-hole 30 and has three radial portions 46A, 46B extending radially. The rear wall portion 46 is connected at the tips of the three radial portions 46A, 46B to the tips (exterior ends) of the three upright portions 42. The lower radial portion 46A, which is a radial portion extending downward, has a bulging portion 50 that bulges toward the interior side of the room, more specifically, toward the lower elongated hole portion 34A.

[0028] In this embodiment, the trim board 12, which is an interior material for a vehicle, has a back wall portion 46, which has the same shape as the through hole 30, formed integrally with the bottom surface portion 22A, which is the plate-shaped main body of the interior material, on the exterior side of the through hole 30. In other words, in this trim board 12, the back wall portion 46 functions as a wall that prevents the interior from being seen, hiding the exterior side of the through hole 30. Furthermore, multiple (eight in this embodiment) through holes 30 are formed in the bottom surface portion 22A, reducing the rigidity of the bottom surface portion 22A, but since multiple upright portions 42 and the back wall portion 46 are provided for each of the through holes 30, the rigidity around the through hole 30 is increased and the rigidity of the trim board 12 itself is ensured.

[0029] The protruding portion 40 has a circular upright wall 48 that is slightly inclined toward the center of the through-hole 30 (the center of the round hole 32) as it extends toward the exterior. Specifically, it is inclined by approximately 3°. As shown in FIG. 4 , the rear wall 46 has the same shape as the through-hole 30, but is slightly smaller in size. Because the protruding portion 40 has this shape, the trim board 12 can be molded by two-sided injection molding. In other words, the trim board 12 has a plurality of mounting portions 24, each consisting of a through-hole 30 and a protruding portion 40, and can be molded by two-sided injection molding, making it relatively easy to manufacture.

[0030] In addition, the thickness of the rear wall portion 46 is smaller than the thickness of the bottom surface portion 22A (see FIGS. 8, 10, etc.). This prevents sink marks from occurring in the rear wall portion 46 during injection molding of the trim board 12, and prevents deterioration of the design even when the rear wall portion 46 is visible from the vehicle interior.

[0031] <Configuration of the first functional component> Next, functional parts that can be attached to and detached from the trim board 12, which is an interior material for a vehicle, will be described. Functional parts that can be attached to and detached from the mounting portion 24 provided on the trim board 12 can be broadly divided into two types depending on the attachment method. The first type of functional part is configured to be attached to and detached from the trim board 12 by sliding, and corresponds to the door pocket 14 and the drink holder 16. Below, the first type of functional part will be described in detail using the door pocket 14 as an example.

[0032] 5, door pocket 14 includes a pocket main body portion (functional component main body portion) 60 that opens upward and allows various items to be placed inside and removed therefrom, and a plurality of latching portions 62 that protrude from a rear surface 60A of pocket main body portion 60 and are latched by mounting portions 24 of trim board 12. Door pocket 14 has latching portions 62 at the four corners of generally rectangular pocket main body portion 60. Incidentally, drink holder 16 includes two latching portions 62 of the same shape, arranged vertically.

[0033] As shown in Figures 5 to 8, the engaging portion 62 has a shape having an axis portion 64 protruding from the back surface 60A of the pocket main body portion 60 in a direction perpendicular to the back surface 60A, and two extension portions 66 extending from the tip of the axis portion 64 in a direction intersecting the axis of the axis portion 64.

[0034] As shown in FIG. 6 , the shaft portion 64 has a generally rectangular cylindrical shape that fits inside the round hole portion 32 of the through hole 30. The two extension portions 66 each extend in a direction inclined 60° forward and backward from a straight line extending vertically upward from the shaft portion 64, and the locked portion 62 is generally V-shaped when viewed from the axial direction. When the locked portion 62 is positioned relative to the through hole 30 so that the shaft portion 64 overlaps the round hole portion 32, the two extension portions 66 overlap the two upper elongated hole portions 34B. In other words, the shape of the locked portion 62, when viewed from the axial direction, fits inside the through hole 30, specifically, inside the round hole portion 32 and the two upper elongated hole portions 34B, and as shown in FIG. 8 , the locked portion 62 is insertable into the through hole 30. That is, in this embodiment, the upper elongated hole portion 34B functions as an insertion elongated hole portion.

[0035] 6, the axial portion 64 has a width W3 in the lateral direction (front-to-back direction) that is slightly smaller than the width W1 of the lower elongated hole portion 34B of the through-hole 30 and larger than the width W2 of the upper elongated hole portion 34A. This allows the locked portion 62 to be inserted into the through-hole 30 only in a position where the two extending portions 66 face upward.

[0036] As shown in Fig. 6, a lower protrusion 64A that protrudes downward and extends in the axial direction is formed on the lower surface of the shaft portion 64, and an upper protrusion 64B that protrudes upward and extends in the axial direction is formed on the upper surface. Furthermore, as shown in Fig. 7, a protrusion 66A that protrudes toward the pocket main body 60 is formed at the tip of each of the two extension portions 66. The protrusion 66A has an inclined lower surface. Furthermore, as shown in Figs. 5 and 6, the pocket main body 60 has a pair of protrusions 6B that extend in the vertical direction in front of and behind the locked portion 62.

[0037] Next, a method for attaching and detaching the door pocket 14 configured as described above to and from the trim board 12 will be described. When attaching the door pocket 14 to the trim board 12, the user holds the pocket main body 60 with the opening facing upward and inserts the four interlocking portions 62 into four of the eight through-holes 30. When the interlocking portions 62 are inserted into the through-holes 30, the shafts 64 of the interlocking portions 62 come into contact with the bulging portions 50 of the rear wall 46, as shown in FIG. 8 . More specifically, the lower ends of the shafts 64 come into contact with the upper portions of the bulging portions 50.

[0038] As described above, the rear wall 46 is connected to the upright portion 42 at the tips of the three radial portions 46A, 46B, and is therefore allowed to bend toward the exterior, but the pair of protrusions 60B provided on the pocket main body 60 abut against the surface (the interior side) of the trim board 12, more specifically, the surface of the bottom portion 22A, preventing the locked portions 62 from pressing too hard against the rear wall 46. Furthermore, when the tips of the locked portions 62 are only touching the bulging portion 50 of the rear wall 46, the pair of protrusions 60B are configured to barely come into contact with the surface of the bottom portion 22A.

[0039] Next, the user can attach the door pocket 14 to the trim board 12 by sliding the door pocket 14 downward. As shown in FIGS. 9 and 10 , the shaft 64 of the locking portion 62 enters the lower elongated hole 34A (which functions as a locking elongated hole), and the two extension portions 66 lock onto the bottom surface 22A from the back surface (outside the vehicle) on both sides of the lower elongated hole 34A in the width direction (front-to-rear direction), thereby locking the locking portion 62 to the mounting portion 24. Note that, in this locking position, the tip of the locking portion 62 abuts against the bulge 50 of the rear wall 46, causing the locking portion 62 to bend outward. In other words, the elastic force of the rear wall 46 biases the locking portion 62 toward the interior of the vehicle, so that the interior surfaces of the two extension portions 66 firmly contact the interior surface of the bottom surface 22A. Therefore, in this embodiment, the mounting portion 24 is configured to lock the locked portion 62 by sandwiching the tip of the locked portion 62 between the indoor side surface of the bottom portion 22A and the bulging portion 50.

[0040] When the locked portion 62 is in the locked position, the convex portions 66A on the two extension portions 66 fit into the concave portions 68 formed on the back surface of the bottom portion 22A, restricting the upward movement of the locked portion 62 and preventing the door pocket 14 from floating off the trim board 12 due to, for example, vehicle vibration. When removing the door pocket 14, the engagement between the convex portions 66A and the concave portions 68 can be easily released by pushing the door pocket 14 toward the exterior and bending the back wall portion 46 toward the exterior. In other words, the user can remove the door pocket 14 by pushing the door pocket 14 toward the exterior and sliding it upward.

[0041] Furthermore, at the insertion position where the locked portion 62 is inserted into the through-hole 30, the tip of the locked portion 62 abuts against the upper surface of the bulge 50. Therefore, as the locked portion 62 moves downward when the door pocket 14 is slid downward, the bulge 50 is displaced toward the exterior of the vehicle and the rear wall 46 is deflected. Conversely, the locked portion 62 receives a reaction force directed toward the interior of the vehicle due to the deflection of the rear wall 46. In other words, according to this embodiment, the rear surface side of the door pocket main body 60 can be prevented from contacting the bottom surface 22A when the door pocket 14 is slid downward.

[0042] Furthermore, the lower protrusion 62A provided on the shaft 64 is a portion that abuts against the upright portion 42 of the mounting portion 24 when the locked portion 62 is in the locked position. On the other hand, the upper protrusion 62B is a portion that abuts against the hole edge of the round hole portion 32 and is used for aligning the locked portion 62 when inserting it into the through-hole 30, and for stopping the upward movement of the locked portion 62 and aligning the locked portion 62 when removing it from the through-hole 30 when removing the door pocket 14. Note that when the locked portion 62 of this door pocket 14 slides up and down, the locked portion 62 does not come into contact with the annular upright wall portion 48 that is formed to surround the through-hole 30.

[0043] As described above, the door trim 10 of this embodiment can prevent scratches on the trim board 12 when attaching or detaching the door pocket 14 or drink holder 16 without providing a cushioned soft material on the back surface 60A of the pocket main body 60.

[0044] <Configuration of the second functional component> Next, the second functional part will be described in detail. The second functional part is configured to be attached to and detached from the trim board 12 by rotating the functional part itself, and corresponds to the hook 18 and the cap 20. First, the cap 20 will be described in detail with reference to FIGS. 11 to 16.

[0045] The cap 20 is intended to close, for example, the through-hole 30 of an unused mounting portion 24 provided in the trim board 12. As described above, the mounting portion 24 closes most of the through-hole 30 due to the presence of the rear wall portion 46, but a gap remains in a portion, and the cap 20 is designed to eliminate the gap and completely cover the through-hole 30. The cap 20 includes a disk-shaped cap main body 70, a suction cup portion 72 that extends radially from the exterior end face of the cap main body 70 around the entire circumference and is elastically deformable, and a locking portion 74 that is provided coaxially with the cap main body 70, protrudes toward the exterior, and is locked by the mounting portion 24 of the trim board 12.

[0046] The locked portion 74 has a cylindrical shaft portion 80 that protrudes from the exterior side surface of the cap main body 70, and three extending portions 82 that extend from the tip of the shaft portion 80 in a direction that intersects with the axis of the shaft portion 80. The three extending portions 82 are provided radially at equal angular intervals (120° intervals) on the outer peripheral surface of the tip of the shaft portion 80. All three extending portions 82 have the same dimensions and shape.

[0047] A hollowed-out portion 82A that penetrates from the interior to the exterior of the vehicle is formed on the tip side of each extending portion 82, and the tip of each extending portion 82 is formed as a thin-walled portion 84. This thin-walled portion 84 functions as a flexible portion that can bend toward the shaft portion 80. Furthermore, a protrusion 84A that protrudes radially is formed in the circumferential center of this thin-walled portion 84.

[0048] The radius of the suction cup portion 72 is larger than the dimension from the center of the through hole 30 (the center of the round hole portion 32) to the tip of the long hole portions 34A and 34b, so that it can sufficiently cover the entire through hole 30.

[0049] Next, a method for attaching and detaching the cap 20 configured as described above to the trim board 12 will be described. When attaching the cap 20 to the trim board 12, a user grasps the cap main body 70 and, as shown in FIG. 13 , aligns and inserts the three extensions 82 of the engaging portion 74 into the three elongated hole portions 34A, 34B of the through-hole 30 to which the cap 20 is to be attached. When the engaging portion 74 is inserted into the through-hole 30, as shown in FIG. 14 , the tip (periphery) of the suction cup portion 72 abuts against the surface of the trim board 12 (the surface of the bottom surface 22A). An annular groove 86 is formed in the surface of the bottom surface 22A, and the peripheral edge of the suction cup portion 72 abuts against the groove 86. Note that instead of the groove 86, a step or a textured surface may be used.

[0050] The user can then rotate the cap main body 70 about the axis, that is, rotate the cap 20 itself about the axis, to attach the cap 20 to the trim board 12. More specifically, as shown in Figures 15 and 16, each of the three extensions 82 is positioned in the center of two of the three elongated hole portions 34A, 34B and engages with the bottom surface portion 22A from the back surface side (the exterior side), whereby the engaged portion 74 is engaged with the mounting portion 24.

[0051] When the cap 20 is rotated from the inserted position, the protrusion 84A of the thin-walled portion 84, which is a flexible portion, of the extension portion 82 first abuts against the first protrusion 44A formed on the annular upright wall portion 48 of the mounting portion 24. As the cap 20 is further rotated, the thin-walled portion 84 bends toward the shaft portion 80 and moves over the first protrusion 44A. However, at the position where the protrusion 84A of the thin-walled portion 84 moves over the first protrusion 44A, the side wall portion 82B of the extension portion 82 abuts against the second protrusion 44B of the upright wall portion 48, preventing further rotation. In other words, the tip of the extension portion 82 is sandwiched between the first protrusion 44A and the second protrusion 44B, preventing the extension portion 82 from moving in the rotational direction. In other words, rotation of the cap 20 itself is restricted, and the cap 20 is attached to the trim board 12.

[0052] As a result of the above-described configuration, the door trim 10 of this embodiment is provided with a stopper mechanism 90 between the annular upright wall portion 48 of the mounting portion 24 as a locking portion and the tip of the extension portion 82 of the locked portion 74, which restricts displacement of the extension portion 82 in the rotational direction at the locking position. Note that this stopper mechanism 90 can be considered to be configured to include the thin-walled portion 84 and the protrusion 84A as a flexible portion at the tip of the extension portion 82, and the first protrusion 44A and the second protrusion 44B of the annular upright wall portion 48. The stopper mechanism 90 is configured to lock the extension portion 82 to the annular upright wall portion 48 by utilizing elastic deformation of the thin-walled portion 84. More specifically, the thin-walled portion 84 elastically deforms to ride over the first protrusion 44A of the annular upright wall portion 48, and the first protrusion 44A restricts rotation of the extension portion 82 toward the insertion position in the rotational direction. By being provided with a stopper mechanism 90 having such a configuration, the door trim 10 can give the user a sense of sensation when the thin-walled portion 84 overcomes the first protrusion 44A and the elastic deformation of the thin-walled portion 84 is released, allowing the user to recognize that the cap 20 is engaged with the trim board 12.

[0053] 13, the mounting portion 24 is configured such that the upright portion 42 has the lateral upright portion 42B. Therefore, after the locked portion 74 of the cap 20 is inserted into the through-hole 30, the user cannot rotate the cap 20 counterclockwise (clockwise in FIG. 13) by manipulating the interior side of the cap 20 because the side wall portion 82C of the extending portion 82 abuts against the lateral upright portion 42B of the upright portion 42. In other words, the user can only rotate the cap 20 clockwise (counterclockwise in FIG. 13) by manipulating the interior side of the cap 20. In other words, in this embodiment, the lateral upright portion 42B of the upright portion 42 functions as a rotation prohibiting portion that prohibits rotation of the cap 20 in one direction from the insertion position.

[0054] Furthermore, when removing cap 20, the user applies a counterclockwise force from inside the room, causing thin-walled portion 84 to elastically deform, and protrusion 84A of thin-walled portion 84 overcomes first protrusion 44A of annular standing wall portion 48, allowing cap 20 to rotate. Then, when the user rotates cap 20 counterclockwise and causes extension portion 82 to abut against lateral standing portion 42B of standing portion 42, interlocking portion 74 is positioned so as to overlap through hole 30, and interlocking portion 74 can be removed from through hole 30, i.e., cap 20 can be removed. As described above, the mounting structure of this embodiment makes it relatively easy to attach and detach cap 20.

[0055] Next, the configuration of the hook 18 will be described. As shown in Fig. 17, the hook 18 has a hook main body 100 that can hook various objects. Therefore, it is desirable to attach the hook main body 100 to the attachment portion 24 with the tip of the hook main body 100 facing upward. The cap 20 described above was configured so that any of the three extension portions 82 could be inserted into any of the three elongated hole portions 34A, 34B, and there was no clear orientation in the rotational direction.

[0056] Hook 18 has a shape similar to that of cap 20 and includes hook main body 100, suction cup 102, and latched portion 104. Similar to latched portion 74 of cap 20, latched portion 104 has a cylindrical shank 110 that protrudes from the exterior surface of hook main body 100 and three extensions 112A, 112B that extend from the tip of shank 110 in a direction intersecting the axis of shank 110. Similar to latched portion 74 of cap 20, three extensions 112A, 112B are provided radially at equal angular intervals (120° intervals) on the outer circumferential surface of the tip of shank 110.

[0057] However, the width W4 of one of the three extending portions, extending portion 112A, is larger than the width W5 of the other two extending portions 112B. Furthermore, the width W5 of extending portion 112B is the same as the width of extending portion 82 of cap 20, and is smaller than the width W1 of lower elongated hole 34A and the width W2 of upper elongated hole 34B. In contrast, the width W4 of extending portion 112A is larger than the width W2 of upper elongated hole 34B and smaller than the width W1 of lower elongated hole 34A. In other words, extending portion 112A can only be inserted into the lower elongated hole 34A.

[0058] Like extension portion 82 of cap 20, extension portions 112A and 1112B also have thin-walled portions 84 that are flexible, and can be attached to mounting portion 24 in the same manner as cap 20. That is, a user inserts interlocking portion 104 of hook 18 at a position where wide extension portion 112A overlaps lower elongated hole 34A, and then rotates it 60 degrees clockwise from inside the vehicle, thereby interlocking interlocking portion 104 with mounting portion 24 and attaching hook 18 to trim board 12. Hook 18 is attached at an interlocking position rotated 60 degrees clockwise from the insertion position, and is always attached with the tip of hook body 100 facing upward.

[0059] The hook 18 also has a suction cup portion 102 that allows it to completely cover the through-hole 30 of the trim board 12. In other words, the second functional component that is attached by rotating can easily hide the through-hole 24 of the attachment portion 24.

[0060] <Features of vehicle interior materials> As described above, the trim board 12, which is an interior material for a vehicle and is provided with the door trim 10 in this embodiment, is capable of detachably mounting two types of functional parts with different mounting methods: the first functional parts 14, 16 that are mounted by sliding, and the second functional parts 18, 10 that are mounted by rotating. This allows it to be used in a variety of ways to suit the needs of the user, making it highly practical.

[0061] <Other embodiments> The present invention is not limited to the above-described embodiment, and can be embodied in various forms with various modifications and improvements based on the knowledge of those skilled in the art. For example, the following embodiments are also included within the technical scope of the present invention.

[0062] (1) In the above embodiment, the mounting structure for the functional component is such that the rear wall portion 46 is integrally formed with the bottom surface portion 22A, which is the interior material main body portion. However, this is not limiting. A plate-shaped member may be provided to cover the multiple through holes 30 from the rear side, and a bulge may be provided on the member.

[0063] (2) In the above embodiment, the mounting structure for the functional component is configured such that the through hole 30 has three elongated hole portions 34A, 34B and the locked portion 62 of the functional component has two extending portions 66. However, the present invention is not limited to this. The number of elongated hole portions and extending portions may be greater than or equal to the number of the through hole portions and extending portions.

[0064] (3) The mounting structure for the functional component in the above embodiment is configured to be able to be attached to the mounting portion 24 by rotating it, like the hook 18 or the cap 20, but this configuration is not essential. Specifically, the engaging portion may be configured not to have the connecting wall portion 44 of the annular standing wall portion 48.

[0065] (4) In the above embodiment, the functional component mounting structure is exemplified by a door trim as an example of a vehicle interior material, but is not limited thereto. The functional component mounting structure of the present invention can also be used for vehicle interior materials other than door trim (instrument panels, luggage trim, seat backboards, etc.). Furthermore, the functional component mounting structure of the present invention can also be used for vehicle interior materials installed in vehicles other than cars, such as trains, airplanes, and ships.
