DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ornament mounting structure for a vehicle wheel.

[0002]

2. Description of the Related Art In a conventional mounting structure of this type, an ornament is bolted to a disk portion of a wheel (Japanese Utility Model Laid-Open No. 52-8331).

[0003]

However, in such a conventional structure, the bolt is simply screwed into the disk portion in a state where the bolt is penetrated through the flange portion of the ornament. The bolts are easily loosened by vibrations during running of the vehicle, and as a result, there is an inconvenience that it takes time to manage the mounting of the ornament.

An object of the present invention is to eliminate such inconvenience.

[0005]

In order to achieve the above object, in an ornament mounting structure for a vehicle wheel according to the present invention, an ornament is provided on a surface side of a disk portion, and the ornament is formed on the disk portion by the ornament. A vehicle wheel ornament mounting structure for covering the axle hole, wherein a required number of locking projections are formed on the disc portion, and the ornament is removably hooked inside the locking projections; A fixing bolt is threaded along the axle direction into a skirt portion of the fixing member, and a tip end surface of the penetrating fixing bolt is brought into contact with the disk portion.

[0006] The locking projection may be formed on a spoke portion of the disc portion.

Further, a skirt portion may be protruded from a peripheral edge of the ornament, and the skirt portion may be fitted inside the axle hole without a gap.

[0008]

Since the ornament mounting structure for a vehicle wheel according to the present invention is constructed as described above, if the fixing bolt is tightened, the ornament is engaged with the disc portion in a state of being locked by the locking projection of the disc portion. Since the distance is to be increased, the friction in the rotational direction between the male screw portion of the fixing bolt and the female screw portion of the ornament with which the fixing bolt is screwed increases.

Since the spoke portion of the disk portion protrudes toward the front surface side, if the locking projection is formed on the spoke portion, the locking projection can be easily formed.

[0010] Further, if a skirt portion is protruded from the peripheral edge of the ornament and the skirt portion is fitted into the axle hole without a gap, water, dust and the like hardly enter the axle hole.

[0011]

In FIG. 1, W is a vehicle wheel, 1 is a disk portion of the wheel W, and R is a rim integrally formed with the disk portion 1. The disk unit 1 is a hub unit 11
And spokes 12, 12, extending radially from the hub 11
….

Next, in FIG. 2, 2 is an axle hole,
The hub 11 is formed at the center. The axle of the vehicle passes through the axle hole 2. Reference numeral 21 denotes an enlarged diameter portion of the axle hole 2, which is formed on the surface side of the hub portion 11. This enlarged part 21
Is for the peripheral edge of the ornament 3 to be inserted. Are locking projections, which are formed at appropriate intervals on the edges of the spoke portions 12, 12,... On the enlarged diameter portion 21 side. The inner diameter of the locking projection 121 is larger than the inner diameter of the enlarged diameter portion 21. In addition, this locking projection
The functions of 121, 121,... Will be described later. Reference numeral 3 denotes a crown-shaped ornament, which is fitted inside the enlarged diameter portion 21 of the hub portion 11.
The ornament 3 covers an axle end penetrating the axle hole 2. Reference numerals 32, 32,... Denote hook portions, which protrude intermittently from the skirt portion 31 of the ornament 3. This hook 32
Is hooked inside the locking projection 121 of the spoke portion 12. Reference numeral 33 denotes a bolt hole,
) 31 is formed along the axle direction. The fixing bolt 4 is screwed into the bolt hole 33. The fixing bolt 4 is threaded into the bolt hole 33 and penetrates the skirt 31 to abut the hub 11. For this reason, if the fixing bolt 4 is tightened, the ornament 3 is turned into the spoke portions 12, 12,.
The distance between the male screw of the fixing bolt 4 and the female screw of the bolt hole 33 is increased in the rotation direction because the distance between the hub 11 and the hub 11 is increased while being locked by the locking projections 121, 121,. For this reason, the fixing bolt 4 is not easily loosened.
The fixing bolt 4 can be appropriately determined according to the relationship with the design of the disk portion 1 and the number or shape of the spokes. For example, the number may be one. Also, 111
Is a locking recess, which is formed in the hub portion 11. The tip of the fixing bolt 4 enters the locking recess 111,
The positioning of the fixing bolt 4 with respect to the hub 11 is performed.

In this ornament mounting structure, in order to mount the ornament 3 on the wheel W, first, the hooks 32, 32,... Of the ornament 3 are positioned between the locking projections 121, 121,. Then, the ornament 3 is fitted into the enlarged diameter portion 21 of the axle hole 2. Then, the ornament 3 is appropriately rotated (around the axis), and the hooks 32, 32,.
Are stopped inside the locking projections 121, 121,... Of the disk portion 1. Then, the ornament 3 is fixed to the wheel W by tightening the fixing bolt 4 and pressing the tip of the fixing bolt 4 against the hub portion 11.

[0014]

According to the present invention, there is provided an ornament mounting structure for a vehicle wheel, in which an ornament is set on a surface side of a disk portion, and the ornament covers an axle hole formed in the disk portion. , A required number of locking projections are formed on the disc portion, the ornament is removably hooked inside the locking projection, and a fixing bolt is screwed along the axle direction at the bottom of the ornament. Since the distal end surface of the penetrated fixing bolt was brought into contact with the disk part, when the fixing bolt was tightened, the ornament was engaged with the disk part while being locked by the locking projection of the disk part. Because the distance is to be increased, the rotation between the male thread of the fixing bolt and the female thread of the ornament with which this fixing bolt is screwed In which the friction in the direction is increased.

Therefore, if this ornament mounting structure is used, the fixing bolt is unlikely to be loosened even when vibration occurs during running of the vehicle, and as a result, the mounting management of the ornament can be easily performed.

Since the spoke portion of the disk portion protrudes toward the front surface, if the locking projection is formed on the spoke portion, the locking projection can be easily formed.

Further, if a skirt is projected from a peripheral edge of the ornament and the skirt is fitted into the axle hole without a gap, water, dust and the like hardly enter the axle hole.
