A cover body 2 is provided. The wheel cover main body 2 is formed in a disk shape so as to substantially cover the rim 3 of the wheel, and a plurality of locking portions 5 that engage with the recesses 4 of the rim 3 are circumferentially provided in the vicinity of the outer periphery on the back surface side. They are arranged at regular intervals along the line. These locking parts 5
Among them, a valve hole 7 through which the valve 6 is inserted is formed between a pair of adjacent locking portions 5a, and the locking portions 5a located on both sides of the valve hole 7 are ring-shaped members described later. It is a stopper.

The locking portion 5 is formed in a flat rectangular shape protruding in parallel with the axle direction, and its outer surface is a curved surface corresponding to the recess 4 of the rim 3. Further, a fitting groove 9 for holding the ring-shaped member 8 having an elastic force is provided on the upper surface of the head of the locking portion 5, and the fitting groove 9 is provided in the valve hole 7.
Are formed along the circumferential direction over both side walls except for the locking portions 5a located on both sides of the. Then, the ring-shaped member 8 can be fitted into the fitting groove 9 from the upper portion of the locking portion 5.

On the other hand, the fitting groove 9 of the locking portion 5a is provided partway toward the valve hole 7, and the inner wall end surface thereof is formed as the stopper surface 9a of the ring-shaped member 8. For this reason, the ring-shaped member 8 is partially notched so as not to pass over the valve hole 7, and both ends thereof have the locking portions 5a provided with stopper surfaces 9a.
It is held in the fitting groove 9 and is configured not to interfere with the valve 6 attached to the rim 3 side. In FIG. 4, reference numeral 10 is a tire assembled to the rim 3 of the wheel.

In the wheel cover 1 configured in this way, when the ring-shaped member 8 is fitted into the fitting groove 9, the elastic force of the ring-shaped member 8 always acts on the locking portion 5 in the outward direction. The locking portion 5 is pressed into contact with the recess 4 of the rim 3 and is securely fixed to the rim 3. Since the ring-shaped member 8 is fitted into the fitting groove 9 from the upper portion of the engaging portion 5, the robot can automatically assemble the wheel cover 1. In addition, both ends of the ring-shaped member 8 that is partially cut away are
Stopper for stopper due to spreading force of ring-shaped member 8 itself
The stopper surface (inner wall end surface) 9a does not fall due to elastic pressure and is retained in the fitting groove 9 of the locking portion 5a, so that a stopper or a welding operation for maintaining the ring shape is unnecessary.

As mentioned above, although one Example of this invention was described, this invention is not limited to the said Example, Various modifications and changes are possible based on the technical idea of this invention.

For example, the wheel cover body 2 in the above-described embodiment
It is needless to say that the shape of the locking portion 5 provided on the vehicle is not limited to that shown in the figure, and can be appropriately selected according to the rim shape of the wheel to be attached.

f. Effect of the Invention As described above, in the wheel cover according to the present invention, a plurality of locking portions that engage with the recesses of the rim of the wheel are arranged at intervals on the outer peripheral surface of the wheel cover body along the circumferential direction. The engaging portions are formed in a planar rectangular shape protruding in parallel with the axle direction, and the outer surface of the engaging portion is formed in a curved surface shape corresponding to the concave portion of the rim, and the engaging portion is formed. A fitting groove for holding an elastic ring-shaped member, a part of which is cut away, is provided on the upper surface of the head of the head, and a valve hole for inserting a valve is provided between a pair of adjoining engaging parts among the engaging parts. By piercing, the fitting grooves of the locking portions located on both sides of the valve hole are provided partway toward the valve hole, and the inner wall end surface serves as the stopper surface of the ring-shaped member so that both sides of the valve hole are formed. The positioned locking portion is configured as a stopper, and the above Ring-shaped member is held by fitting the fitting groove, since is pressed against the locking portion to the rim of the wheel by the resilience of the ring-shaped member, the following effects can be obtained.
