BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel cap, and more particularly to a structure in which an elastic ring is used to attach a plastic wheel cap body to a wheel rim.

[0002]

2. Description of the Related Art In recent automobiles, various efforts have been made to improve their commercial properties.

[0003] For example, for a wheel cap for an automobile, a plastic wheel cap has been used instead of a metal wheel cap from the viewpoint of decoration and weight reduction. Because of this, there is a possibility that the wheel cap may fall off, so it is an important issue how to mount the wheel cap body.

Conventionally, in this type of wheel cap, a structure in which a wheel cap body is attached to a wheel rim by using an elastic ring has been widely adopted (for example, Japanese Utility Model Laid-Open No. 61-97001, Japanese Utility Model Laid-Open No. 62-1987). No. 61702). That is, as shown in FIG. 5, the pillar portion 4 is integrally formed on the wheel cap main body, the locking concave portion 40 is provided on the inner surface of the pillar portion 4, and the elastic piece is provided by a locking piece provided integrally or separately. Whether the ring 5 is locked in the locking recess 40,
Alternatively, the elastic ring 5 is elastically locked to the locking recess 40 by the spring force of the elastic ring 5 itself, and the strut portion 4 is pressed against the wheel rim by the elastic force of the elastic ring 5 to attach the wheel cap body to the wheel rim. It is.

[0005]

However, in the conventional wheel cap, when the wheel cap main body is molded by a die, first, as shown in FIG. 7 is slid in the A direction, and secondly, the male mold 6 is pulled out in the B direction. However, the locking recess 40 of the under-shaped support portion 4 first forcibly removes the male mold 6 by utilizing the elastic deformation of the support portion 4 after the slide core 7 is slid. Therefore, not only was the die removal of the product very complicated, but also the die structure was complicated.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a wheel cap capable of easily removing a product when a wheel cap body is molded.

[0007]

Therefore, a wheel cap according to the present invention is divided into a plurality of elastic struts integrally formed with a plastic wheel cap main body, and each strut is divided into a plurality of struts. A U-shaped recessed portion extending in the axial direction formed in a part of the strut, a locking claw provided in a portion of the strut portion where the recessed portion is not formed, and a full recessed portion are fitted. And an elastic ring to be combined,
The locking claw holds the elastic ring near the bottom of the recessed portion. "

[0008]

[Function] In the present invention, each support part is divided into a plurality of parts,
A U-shaped concave portion extending in the axial direction is formed in a part of the divided portion, and a locking claw is provided in a portion of the divided portion where the concave portion is not formed, and an elastic ring is fitted into the concave portion. At the same time, since this is held at the bottom of the recess by the locking claw, the locking claw can be set on the outer surface side of the support portion. The locking claw can be formed by a mold surface that forms the outer surface of the support column without providing a male mold.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to specific examples shown in the drawings. 1 and 2 show a wheel cap according to an embodiment of the present invention. In the figure, a wheel cap body 1 is mounted on a wheel rim 2 of an automobile, and the wheel cap body 1 is formed by molding using a synthetic resin material. The parts 10 are integrally formed at appropriate intervals,
The strut portion 10 is pressed against the hump portion 20 of the wheel rim 2, and thus the wheel cap body 1 is fixed to the wheel rim 2.

As shown in FIG. 2, the distal end of the column 10 is divided into three by forming two slits 11 at predetermined intervals in the axial direction, and the central column 12 has an axial direction. A U-shaped recessed portion 13 is formed. On the other hand, the outer side portions of the both-side support portions 14 and 15 are cut out in a rectangular parallelepiped shape and formed to have the same thickness as the inner side wall portion of the recessed portion 13 of the central support portion 12. Are provided with locking claws 16 protruding therefrom.

An elastic ring 3 is fitted into the recess 13 of each of the plurality of central support portions 12.
Are formed on the outer surfaces of both side support portions 14 and 15, and the concave portions 1
The elastic ring 3 is attached to the concave portion 13 of the column 10 by the locking claw 16 located on the side of the column 3, and the elastic ring 3 is attached to the column 13 by the elastic force of the elastic ring 13. 10 is pressed against the hump portion 20 of the wheel rim 2.

Next, the function and effect will be described.

In the wheel cap of the present embodiment as described above, when the support 10 of the wheel cap body 1 is pressed against the hump 20 of the wheel rim 2, each support 10
Is divided into three, and a U-shaped recessed portion 13 extending in the axial direction is formed in the central support portion 12 of the divided portions, while the two-sided support portion 1 in which the recessed portion 13 is not formed is formed.
4 and 15 are provided with locking claws 16, and the elastic ring 3 is fitted into the concave portion 13, and the elastic ring 3 is fitted into the U-shaped concave portion 13 extending in the axial direction of the column 10, and this is inserted into the both-side column. The wheel cap body 1 is held by the locking claws 16 formed on the portions 14 and 15.
Can be securely fixed to the wheel rim 2 and the wheel cap main body 1 can be reliably prevented from dropping unexpectedly due to running vibration or the like.

In addition, the elastic ring 3 is fitted into the U-shaped recess 13 of the column 10 and is locked by the locking claw 16, so that, for example, the wheel described in Japanese Utility Model Application Laid-Open No. 61-97001 is disclosed. Unlike the cap, there is no need to separately provide a locking piece to lock the elastic ring, and the mounting structure of the elastic ring 3 can be extremely simplified.

Further, in the wheel cap of the present embodiment,
A U-shaped recessed portion 13 extending in the axial direction is formed in the central support portion 12 of the support portion 10, and both side support portions 14, 15 are formed.
