Engages with the wheel nut 7 to maintain a stable mounting state.

[Problems to be solved by the invention]

However, in such a conventional hub cap, the number of the wheel nuts 7 is large, and accordingly, the number of the mounting tongues 4 is large. For example, when the number is 5 or more, the last one is left. When the other mounting tongue 4 is inserted, the last mounting tongue 4 largely projects to the outside in the radial direction of the hub cap 1, and if there are too many mounting tongues, the bending allowance cannot be made large. Since it is difficult and the tightening margin between the mounting tongue 4 and the wheel nut 7 cannot be made large, the mounting force of the hub cap 1 becomes weak, and there is a problem that rattling easily occurs after mounting.

The present invention is intended to solve the above problems, and an object thereof is to obtain a vehicle hub cap that can be easily and stably mounted even when the number of wheel nuts is large.

[Means for solving problems]

This invention is a hub cap for covering the tip of an axle protruding from a road wheel attached to a vehicle body with five or more wheel nuts, and a cap-shaped hub cap body for covering the tip of the axle. Three or more mounting tongues that protrude from the open end of the cap body to the outer peripheral direction of the hub cap body and engage with the lower inclined surface of the wheel nut, and a hub cap without these mounting tongues. From the open end of the body,
Two or more dummy tongues protruding beyond the outer peripheral portion of the hub cap body and having a length that does not engage with the wheel nut, wherein the attachment tongue and the dummy tongue face the wheel nut of the hub cap body. Are arranged in a position where one or two adjacent mounting tongues are respectively provided with one or more dummy tongues, and the inside of each side of the polygon having each mounting tongue as an apex. The hub cap for a vehicle is characterized in that the mounting tongue is arranged so that the axis of the hub cap body exists.

[Action]

In the hub cap for a vehicle of the present invention, one or two mounting tongues sandwiched between the dummy tongues are left, and the tip of the other mounting tongue is placed between the lower inclined surface of the wheel nut and the road wheel. , And then engage the remaining one or two mounting tongues from above the wheel nut while elastically deforming the dummy tongue near the hub cap body, and push it in to lower the inclined surface of the wheel nut. Between the road wheel and the road wheel, and engage and attach.

When mounting, it is not necessary to engage the dummy tongue,
Moreover, since the number of mounting tongues to be engaged first is small, the remaining mounting tongues do not significantly protrude to the outside of the hub cap in the radial direction, and both sides of the remaining mounting tongues are dummy tongues. Since the bending margin is large, it is easy to push in the remaining mounting tongue.

In the mounted state, the mounting tongue is arranged so as to surround the axis of the hub cap body from the surroundings, so the pressing force of the mounting tongue is applied in a well-balanced manner toward the axis.
Since the tightening margin of the mounting tongue and the wheel nut can be made large,
The hub cap maintains a stable mounting condition. In addition, since the dummy tongue protrudes in the part without the mounting tongue, it is possible to prevent the side surface of the hub cap body from coming into contact with the wheel nut and being damaged when the hub cap is mounted or removed, and the opening of the hub cap body The strength of the edges is balanced, which increases the mounting stability and reduces the appearance of strangeness.

〔Example〕

Hereinafter, the present invention will be described with reference to embodiments of the drawings. FIG. 1 is a front view showing the hub cap of the embodiment, and FIG. 2 is its II-I.
Sectional view I, FIG. 3 is a sectional view taken along the line III-III, and FIG. 4 is a sectional view taken along the line IV-IV. In FIGS. 8 to 13, the same reference numerals indicate the same or corresponding portions.

The basic structure of the hub cap 1 is almost the same as the conventional one, but three mounting tongues 4 are formed at the A, C and D positions, and the wheel nut 7 is engaged at the B and E positions. Two dummy tongues 13 that do not project so as to face the lower inclined surface 8 of the wheel nut 7. On the outer surface side of the concave locking portion 9 formed at the center of the tip of the mounting tongue 4, a locking surface 10 formed of a partially conical inclined surface corresponding to the lower inclined surface 8 of the wheel nut 7 is formed. Has been done. On the rear surface side of the locking portion 9, that is, the road wheel 6 side, the axis O of the hub cap 1
A guide surface consisting of a conical inclined surface with one point Q above as the apex
11 are formed. The dummy tongue piece 13 has a structure in which a tip end portion of the mounting tongue piece 4 that engages with the wheel nut 7 is cut away, and projects with a length that does not engage with the wheel nut 7. The dummy tongues 13 are arranged on both sides of one mounting tongue 4 at the position A, and each mounting tongue 4 is arranged so as to include the axis O inside each side of the triangle having the apex thereof. Other configurations are the same as the conventional ones.

In the hub cap 1 having the above-mentioned configuration, the tip of the mounting tongue 4 at the C and D positions is loaded onto the lower inclined surface 8 of the wheel nut 7 while leaving the mounting tongue 4 at the A position sandwiched between the dummy tongues 13. After being inserted between the wheels 6 to engage the locking portion 9 and the locking surface 10 with the lower inclined surface 8 of the wheel nut 7, the remaining A
The mounting tongue 4 at the position is pushed in from above the wheel nut 7 while elastically deforming the dummy tongue 13 of the hub cap body 3 so that the locking portion 9 and the locking surface 10 are locked.
To engage the lower inclined surface 8 of. At this time, the conical guide surface 11 of the mounting tongue 4 slides along the outer periphery of the wheel nut 7, and is inserted between the lower inclined surface 8 of the wheel nut 7 and the road wheel 6.

At the time of mounting, the dummy tongue pieces 13 do not need to be engaged, and the number of mounting tongue pieces 4 to be engaged first is small, so that the remaining mounting tongue pieces 4 largely protrude to the outside in the radial direction of the hub cap 1. Since the dummy tongue pieces 13 are provided on both sides of the remaining mounting tongue piece 4, the bending allowance is large, and thus the remaining mounting tongue piece 4 can be easily pushed.

In the mounted state, since the mounting tongue 4 is arranged so as to surround the axis O of the hub cap body 3 from the periphery, the pressing force P by the mounting tongue 4 is applied to the axis O in a well-balanced manner and Since the tightening margin between the piece 4 and the wheel nut 7 can be set large, the hub cap 1 maintains a stable attached state. Dummy tongue 13
Since it protrudes, it is possible to prevent the side surface of the hub cap body 3 from coming into contact with the wheel nut 7 and being scratched at the time of mounting or removing, and the strength of the opening end portion of the hub cap body 3 is balanced, so that the mounting stability can be improved. Becomes higher, and the discomfort in appearance also decreases.

Three dummy tongue pieces 13 are formed at the B, D, and F positions, and the mounting tongue piece 4 at the C and E positions is first inserted, and finally the mounting tongue piece 4 at the A position is pushed. In Fig. 6, it is 4 at A, C, D, E positions.
One mounting tongue 4 is formed, and two dummy tongues 13 are formed at the B and F positions. First, the mounting tongues 4 at the C, D and E positions are formed.
After inserting, the mounting tongue 4 at the A position is finally pushed in.
In FIG. 7, four mounting tongues 4 are formed at positions A, B, D and E, and two dummy tongues 13 are formed at positions C and F,
First, the mounting tongue 4 at the D, E (or A, B) position is inserted, and finally, the mounting tongue 4 at the A, B (or C, D) position is pushed.

In the above embodiment, the case where the number of the wheel nuts 7 (the total number of the mounting tongues 4 and the dummy tongues 13) is 5 or 6 has been described, but the case of 7 or more is also applicable. Further, although the guide surface 11 is formed in a conical shape, if the guide surface 11 is formed in a polygonal pyramid shape having Q as an apex, the pushing operation becomes easier.

[Effect of device]

According to the present invention, since the mounting tongue and the dummy tongue are formed on the hub cap, even when the number of the wheel nuts is large, the protrusion of the mounting tongue to be pushed last is made small and the bending allowance is increased to facilitate the operation.
