[0005] SUMMARY OF THE INVENTION In consideration of the above, an object of the present invention is to provide a mounting structure for a decorative member on a wheel that can prevent the decorative member from falling off due to centrifugal force. [Means for solving the problem]

[0006] The mounting structure for a decorative member on a wheel in the first aspect comprises a wheel, a base member attached to the outer surface of the wheel, a decorative member attached to the outer surface of the base member, and a movement limiting portion that engages with the decorative member when the decorative member moves radially outward relative to the base member as the wheel rotates, thereby limiting the movement of the decorative member radially outward.

[0007] The mounting structure for a decorative member on a wheel of the second aspect is the mounting structure for a decorative member on a wheel of the first aspect, in which a plurality of the decorative members are mounted on the base member, and one of the decorative members is provided with a movement limiting portion that limits the movement of the other decorative members outward in the direction of the rotational radius, and the other decorative members are provided with a movement limiting portion that limits the movement of the one decorative member outward in the direction of the rotational radius.

[0008] The mounting structure for a decorative member on a wheel according to the third aspect is the mounting structure for a decorative member on a wheel according to the second aspect, in which three or more decorative members are attached to the base member, and the movement limiting portion of one of the decorative members limits the movement of the other two or more decorative members outward in the radial direction of rotation.

[0009] The mounting structure for a decorative member on a wheel in the fourth aspect is the same as the mounting structure for a decorative member on a wheel in the first aspect, in which the movement limiting portion is provided on the base member, and a portion of the decorative member is fitted into the movement limiting portion. [Effects of the Invention]

[0010] In the wheel decorative member mounting structure according to the first aspect, a base member is attached to the outer surface of the wheel. The decorative member is also attached to the outer surface of the base member. When the decorative member moves radially outward relative to the base member as the wheel rotates, the decorative member is locked by the movement limiting portion. This allows the movement limiting portion to limit the radially outward movement of the decorative member. As a result, the decorative member can be prevented from falling off due to centrifugal force.

[0011] In the wheel decorative member mounting structure according to the second aspect, when one decorative member moves radially outward, the first decorative member is locked by a movement limiting portion provided on the other decorative member. Furthermore, when the other decorative member moves radially outward, the other decorative member is locked by a movement limiting portion provided on the first decorative member. This allows the movement limiting portions provided on each decorative member to limit the radially outward movement of the first decorative member and the other decorative member. As a result, it is possible to prevent the first decorative member and the other decorative member from falling off due to centrifugal force.

[0012] In the wheel decoration member mounting structure according to the third aspect, the movement limiting portion of one decoration member can limit the radially outward movement of the other two or more decoration members.

[0013] In a fourth aspect of the wheel decorative member mounting structure, a movement limiting portion is provided on the base member, and a portion of the decorative member is fitted into the movement limiting portion. In this configuration, the movement of the decorative member outward in the rotational radial direction can be limited by the movement limiting portion provided on the base member. As a result, the decorative member can be prevented from falling off due to centrifugal force. [Brief explanation of the drawings]

[0015] 1 to 3, the configurations of a wheel 10, a base member 12, and a decorative member 14 to which the mounting structure for a wheel decorative member according to an embodiment of the present invention is applied will be described. Note that arrows C, R, and Z shown in the figures indicate one side in the rotational circumferential direction of the wheel 10, the outer side in the rotational radial direction, and one side in the rotational axial direction, respectively. Furthermore, in the following description, unless otherwise specified, when the circumferential direction, radial direction, and axial direction are indicated, they will respectively indicate the rotational circumferential direction, rotational radial direction, and rotational axial direction of the wheel 10.

[0016] As shown in FIG. 1, a base member 12 is attached to one axially facing outer surface of the wheel 10. This base member 12 is circular when viewed from one axially facing side. Also, as shown in FIGS. 1 and 2, five decorative members 14 are attached to one axially facing outer surface of the base member 12. These five decorative members 14 are arranged at equal intervals along the circumferential direction. The five decorative members 14 are referred to as the first decorative member 14A, the second decorative member 14B, the third decorative member 14C, the fourth decorative member 14D, and the fifth decorative member 14E, in order from the other circumferential side to the one axial side. Centrifugal forces F1, F2, F3, F4, and F5, respectively, act on the first decorative member 14A, the second decorative member 14B, the third decorative member 14C, the fourth decorative member 14D, and the fifth decorative member 14E as the wheel 10 rotates. The following describes a configuration for preventing the first decorative member 14A, the second decorative member 14B, the third decorative member 14C, the fourth decorative member 14D, and the fifth decorative member 14E from falling off the base member 12 due to centrifugal forces F1, F2, F3, F4, and F5. To facilitate understanding of the present invention, the following description will be given with the number of decorative members 14 reduced from five to four.

[0017] 3, the first decorative member 14A has a first extension portion 16 that extends parallel to the radial direction at a position offset radially outward from the rotation center of the wheel 10 and the base member 12. The first decorative member 14A also has a second extension portion 18 that bends and extends from a radially inner end of the first extension portion 16 toward the rotation center of the wheel 10 and the base member 12. The first decorative member 14A also has a third extension portion 20 that bends and extends from an end of the second extension portion 18 opposite the first extension portion 16 toward the rotation center of the wheel 10 and the base member 12. The area from the radially inner end of the first extension portion 16, via the second extension portion 18, to the third extension portion 20 has a J-shaped (hook-shaped) bend. Furthermore, the end of the second extension portion 18 on the third extension portion 20 side and the entire third extension portion 20 constitute a movement limiting portion 22 that limits the radially outward movement of the second decoration member 14B, the third decoration member 14C, and the fourth decoration member 14D. An outer engagement portion 24 that engages with the base member 12 is provided at the radially outer end of the first extension portion 16 (the side opposite the second extension portion 18). Furthermore, the third extension portion 20 is provided with an inner engagement portion 26 that engages with the base member 12. The outer engagement portion 24 and the inner engagement portion 26 engage with the base member 12, thereby attaching the first decoration member 14A to the base member 12.

[0018] Here, the second decorative member 14B, the third decorative member 14C, and the fourth decorative member 14D are configured similarly to the first decorative member 14A, so the parts of the second decorative member 14B, the third decorative member 14C, and the fourth decorative member 14D that correspond to those of the first decorative member 14A are given the same reference numerals as those of the parts of the first decorative member 14A, and their description will be omitted.

[0019] When the second decorative member 14B is attached to the base member 12, the movement limiting portion 22 of the first decorative member 14A is positioned along the second extension portion 18 between the first extension portion 16 and the third extension portion 20 of the second decorative member 14B.

[0020] When the third decorative member 14C is attached to the base member 12, the movement limiting portion 22 of the second decorative member 14B is positioned along the second extension portion 18 between the first extension portion 16 and the third extension portion 20 of the third decorative member 14C.

[0021] When the fourth decorative member 14D is attached to the base member 12, the movement limiting portion 22 of the third decorative member 14C is positioned along the second extension portion 18 between the first extension portion 16 and the third extension portion 20 of the fourth decorative member 14D.

[0022] When the first decorative member 14A is attached to the base member 12, the movement limiting portion 22 of the fourth decorative member 14D is positioned along the second extension portion 18 between the first extension portion 16 and the third extension portion 20 of the first decorative member 14A.

[0023] (Actions and Effects of This Embodiment) Next, the operation and effects of this embodiment will be described.

[0024] As shown in FIG. 3, when a centrifugal force F1 acts on the first decorating member 14A as the wheel 10 (see FIG. 1) rotates, the first decorating member 14A moves radially outward. As the first decorating member 14A moves radially outward, the second extension 18 of the first decorating member 14A engages with the movement limiting portion 22 of the fourth decorating member 14D. As the first decorating member 14A moves radially outward, the third extension 20 of the first decorating member 14A engages with the movement limiting portion 22 of the second decorating member 14B. As the first decorating member 14A moves radially outward, the second extension 18 of the first decorating member 14A engages with the movement limiting portion 22 of the third decorating member 14C via the third extension 20 of the fourth decorating member 14D. This limits the radially outward movement of the first decorating member 14A.

[0025] Furthermore, as the wheel 10 (see FIG. 1) rotates, centrifugal force F2 acts on the second decoration member 14B, causing the second decoration member 14B to move radially outward. When the second decoration member 14B moves radially outward, the second extension portion 18 of the second decoration member 14B engages with the movement limiting portion 22 of the first decoration member 14A. When the second decoration member 14B moves radially outward, the third extension portion 20 of the second decoration member 14B engages with the movement limiting portion 22 of the third decoration member 14C. When the second decoration member 14B moves radially outward, the second extension portion 18 of the second decoration member 14B engages with the movement limiting portion 22 of the fourth decoration member 14D via the third extension portion 20 of the first decoration member 14A. This limits the radially outward movement of the second decoration member 14B.

[0026] Furthermore, as the wheel 10 (see FIG. 1) rotates, centrifugal force F3 acts on the third decorative member 14C, causing the third decorative member 14C to move radially outward. When the third decorative member 14C moves radially outward, the second extension portion 18 of the third decorative member 14C engages with the movement limiting portion 22 of the second decorative member 14B. When the third decorative member 14C moves radially outward, the third extension portion 20 of the third decorative member 14C engages with the movement limiting portion 22 of the fourth decorative member 14D. When the third decorative member 14C moves radially outward, the second extension portion 18 of the third decorative member 14C engages with the movement limiting portion 22 of the first decorative member 14A via the third extension portion 20 of the second decorative member 14B. This limits the radially outward movement of the third decorative member 14C.

[0027] Furthermore, as the wheel 10 (see FIG. 1) rotates, centrifugal force F4 acts on the fourth decoration member 14D, causing the fourth decoration member 14D to move radially outward. When the fourth decoration member 14D moves radially outward, the second extension portion 18 of the fourth decoration member 14D engages with the movement limiting portion 22 of the third decoration member 14C. When the fourth decoration member 14D moves radially outward, the third extension portion 20 of the fourth decoration member 14D engages with the movement limiting portion 22 of the first decoration member 14A. When the fourth decoration member 14D moves radially outward, the second extension portion 18 of the fourth decoration member 14D engages with the movement limiting portion 22 of the second decoration member 14B via the third extension portion 20 of the third decoration member 14C. This limits the radially outward movement of the fourth decoration member 14D.

[0028] As described above, in this embodiment, the radial outward movement of the first decorative member 14A, the second decorative member 14B, the third decorative member 14C, and the fourth decorative member 14D due to the centrifugal forces F1, F2, F3, and F4 can be limited. This makes it possible to prevent the first decorative member 14A, the second decorative member 14B, the third decorative member 14C, and the fourth decorative member 14D from falling off the base member 12 due to the centrifugal forces F1, F2, F3, and F4. Furthermore, by applying the configuration of this embodiment, even if the decorative member 14 is formed using a material with a higher specific gravity than a resin material (e.g., carbon, aluminum, etc.), it is possible to prevent the decorative member 14 from falling off the base member 12.

[0029] Furthermore, in this embodiment, the movement limiting portion of one decorative member 14 (e.g., the first decorative member 14A) can limit the radially outward movement of the other three decorative members 14 (the second decorative member 14B, the third decorative member 14C, and the fourth decorative member 14D). In this configuration, the inner engaging portion 26 of the first decorative member 14A is subjected to centrifugal forces F1 of the first decorative member 14A, F2 of the second decorative member 14B, F3 of the third decorative member 14C, and F4 of the fourth decorative member 14D. However, these centrifugal forces F1, F2, F3, and F4 cancel each other out, thereby preventing a decrease in the durability of the inner engaging portion 26 of the first decorative member 14A. For the same reason, it is possible to prevent a decrease in durability of the inner engaging portions 26 of the second, third and fourth decorative members 14B, 14C and 14D.

[0030] In this embodiment, an example in which the movement restricting portion 22 is provided on the decorative member 14 side has been described, but the present invention is not limited to this. For example, as in another embodiment shown in Fig. 4, a configuration in which the movement restricting portion 22 is provided on the base member 12 side may also be employed.

[0031] The configuration of another embodiment shown in Fig. 4 will be described below. Note that in the base member 12 and the decorative member 14 shown in Fig. 4, the members and parts corresponding to those of the base member 12 and the decorative member 14 of the above-described embodiment are denoted by the same reference numerals as those corresponding to those of the base member 12 and the decorative member 14 of the above-described embodiment, and their description may be omitted.

[0032] 4, the movement limiting portion 22 is formed integrally with or fixed to the base member 12. The movement limiting portion 22 is disposed at the rotation center of the base member 12 and is formed in the shape of a rectangular block protruding toward one axial side. Furthermore, four fitting grooves 28 that are open on one axial side and on the radially outer side are formed along the radial direction at a radially outer portion of the movement limiting portion 22. These four fitting grooves 28 are disposed at equal intervals along the circumferential direction.

[0033] 4, each decorative member 14 includes a first extending portion 16 and a second extending portion 18. The area from the radially inner end of the first extending portion 16 to the second extending portion 18 is bent in an L-shape (hook shape).

[0034] Each decoration member 14 is attached to the base member 12 with the second extension portion 18 of each decoration member 14 fitted into the corresponding fitting groove 28 .

[0035] In the other embodiments described above, the radial outward movement of the first decorative member 14A, the second decorative member 14B, the third decorative member 14C, and the fourth decorative member 14D due to the centrifugal forces F1, F2, F3, and F4 can also be restricted, thereby preventing the first decorative member 14A, the second decorative member 14B, the third decorative member 14C, and the fourth decorative member 14D from falling off the base member 12 due to the centrifugal forces F1, F2, F3, and F4.

[0036] The configurations of the above-described embodiments can also be combined with each other.

[0037] The above describes one embodiment of the present invention, but the present invention is not limited to the above, and it goes without saying that it can be implemented in various other modified forms within the scope of the gist of the present invention. [Explanation of symbols]
