BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hub cap for a wheel of a vehicle such as an automobile.

[0002]

2. Description of the Related Art A conventional hub cap is shown in FIGS.
As shown in FIG. 1, a cap body 1 made of resin, a plurality of arc-shaped locking claws 2 which protrude radially along a circumferential direction on a peripheral portion 3 of the cap body 1 and are formed intermittently, And a concave portion 4 provided by cutting out a part of the arc-shaped locking claw 2. At a substantially center of the concave portion 4, a slope portion 4a is formed which engages with a tapered portion 5a of a wheel nut 5 fixed around the cap body 1. When attaching the hub cap to a wheel of a vehicle such as an automobile, the peripheral portion 3 of the cap body 1 made of resin is disposed at a position corresponding to the wheel nut 5, and the cap body 1 is rotated to engage the circular arc. The claw 2 is elastically deformed in the radial direction so that the tapered portion 5a of the wheel nut 5 is engaged with the inclined surface 4a of the concave portion 4 so that the cap body 1
Is fixed. A hub cap for a wheel having the above structure is known. For example, Japanese Utility Model Publication No. 58-8561 discloses a wheel cap having the above structure.

[0003]

By the way, in the conventional hub cap, since a plurality of arc-shaped engaging claws 2 are partially cut away to form the concave portion 4, when the cap body 1 is excessively rotated. The cap body 1 over the recess 4
Cannot be securely fixed, and the cap body 1 tends to fall off. Further, since the plurality of arc-shaped locking claws 2 having the concave portions 4 are all of the same shape, when the cap body 1 is rotated to bring the plurality of arc-shaped locking claws 2 into contact with the wheel nut 5, There has been a disadvantage that stress is simultaneously applied to the plurality of arcuate locking claws 2 and it is difficult to rotate the cap body 1. For this reason, it has been difficult to attach the hub cap to the wheel.

Therefore, an object of the present invention is to provide a hub cap which can be easily attached to wheels of a vehicle such as an automobile.

[0005]

The hub cap according to the present invention comprises a resin cap body and a plurality of arc-shaped intermittently formed radially projecting along the circumferential direction of the peripheral edge of the cap body. A locking claw; and a recess provided on each of the plurality of arc-shaped locking claws and engaged with a wheel nut fixed around the cap body. In this hub cap, a small protrusion is formed at one end of each of the plurality of recesses by shifting the position in the rotation direction of the cap body, and a locking protrusion for locking to the wheel nut is formed at the other end of the recess. .

[0006]

When the peripheral portion of the resin cap body is arranged at a position corresponding to the wheel nut and the cap body is rotated, the wheel nut sequentially rides on the small projections of the plurality of recesses to lock the plurality of arcs. The pawls are sequentially elastically bent in the radial direction, and the wheel nuts are sequentially locked to the locking projections of the recess with a sense of moderation. By fixing the cap body by reducing the stress applied to each arc-shaped locking claw, the hub cap can be easily attached.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a hub cap according to the present invention will be described below with reference to FIGS. However, in FIG. 1, the same portions as those shown in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted. As shown in FIG. 1, the hub cap of this embodiment includes a cap body 1 made of resin and a plurality of intermittently formed projecting radially along a circumferential direction of a peripheral portion 3 of the cap body 1. And an arcuate locking claw 2.
The cap body 1 and the plurality of arcuate locking claws 2 are, for example, FR.
It is molded integrally with a synthetic resin such as P (glass fiber reinforced plastic). The plurality of arc-shaped locking claws 2 are provided on the cap body 1.
The first to third concave portions 6 to 8 are formed in some of the arc-shaped locking claws 2 at equal angular intervals with respect to the center. The first to third concave portions 6 to 8 have slope portions 6c to 8c which engage with the tapered portion 5a (FIG. 5) of the wheel nut 5 fixed to the periphery of the cap body 1. As shown in FIG.
First to third small protrusions 6a to 8a are formed at one ends of the first to third recesses 6 to 8 so as to be shifted in the rotation direction of the cap body 1, respectively. The other ends of 6 to 8 are formed with first to third locking projections 6b to 8b which are locked to the wheel nut 5.

When the hub cap having the above configuration is attached, the peripheral portion 3 of the resin cap body 1 is arranged at a position corresponding to the wheel nut 5 so that the cap body 1
Is rotated clockwise toward the drawing. At this time, the tapered portion 5a (FIG. 5) of the wheel nut 5 sequentially rides on the small projections 6a to 8a of the first to third recesses 6 to 8, and the arc-shaped locking claws 2 are elastically deformed sequentially radially inward. I do. When the cap body 1 is further rotated clockwise, the tapered portion 5a (FIG. 5) of the wheel nut 5 is sequentially engaged with the slope portions 6c to 8c with a sense of moderation, and the first to third concave portions 6 to 8 are formed. The cap body 1 is sequentially locked by the locking projections 6b to 8b, and the cap body 1 is fixed at a proper position.

As described above, in this embodiment, the positions of the first to third concave portions 6 to 8 of the plurality of arc-shaped engaging claws 2 are shifted in the rotation direction of the cap body 1 to the first ends. Since the third small projections 6a to 8a are formed, the stress applied to each arc-shaped locking claw 2 can be reduced, and the hub cap can be easily attached. In addition, since the first to third locking projections 6b to 8b are formed at the other ends of the first to third recesses 6 to 8, the cap body 1 can be easily fixed at the regular position. Further, the first to third concave portions 6 to
Since the tapered portions 5a (FIG. 5) of the wheel nuts 5 are sequentially locked to the locking projections 6b to 8b of FIG.

The embodiment of the present invention is not limited to the embodiment described above, and various modifications are possible. For example, in the illustrated example, an example in which the first to third concave portions 6 to 8 are formed in some of the arc-shaped locking claws 2 is shown, but a plurality of concave portions are formed in all of the arc-shaped locking claws 2. May be. It goes without saying that the number of the plurality of recesses is not limited to three. Further, the positional relationship between each of the small projections 6a to 8a of the first to third recesses 6 to 8 and each of the locking projections 6b to 8b may be reversed.

[0011]

According to the present invention, the cap body is fixed by reducing the stress applied to each of the arc-shaped locking claws, so that the hub cap can be easily attached to the wheels of a vehicle such as an automobile. Can be simplified. Further, since the wheel nuts are sequentially locked to the locking projections of the plurality of recesses with a sense of moderation, it is possible to prevent the cap main body from falling off due to illegal rotation of the cap main body.
