[0002]

2. Description of the Related Art Conventionally, fog lamps have been separately attached as accessories to a lower portion of a front bumper. In recent years, fog lamps are sometimes provided as standard equipment so as to be disposed in lamp placement holes formed in the front bumper.

When the fog lamp is separately mounted, the optical axis is adjusted by mounting adjustment using a mounting bracket. However, when the fog lamp is incorporated in a front bumper, the lamp itself is provided with a mechanism for vertically adjusting the optical axis in order to fix the lamp to the front bumper. It is necessary to use a fog lamp, and the use of a lamp configured to adjust the position of the light bulb with respect to a reflecting mirror and a lamp lens like a headlight increases the cost.

[0005] Therefore, as shown in FIG. 5, a lamp 31 having a lamp body 32 in which the position of a light bulb is fixed is supported by a lamp bracket 33 via a connecting portion 34 so as to be vertically swingable.

In a state where the lamp main body 32 is disposed on the lamp 6, the lamp bracket 33 is fastened and fixed to a mounting boss 37 protruding from the rear surface of the front bumper 35 with a mounting screw 38.

Incidentally, Japanese Utility Model Laid-Open No. 4-99145 discloses that
To mount the lamp on the front bumper made of resin, the clip provided on the lamp is engaged and fixed to the rib formed on the front bumper, and the mounting bracket extending rearward from the lamp is bolted to the frame member on the vehicle body side. Is disclosed.

[0006]

However, in the configuration shown in FIG. 5, when the weight of the lamp 31 is heavy, the rigidity of the front bumper 35 made of synthetic resin is not large, so that the lamp body is caused by the running vibration of the automobile. 32 vibrates, the optical axis is blurred, and the front becomes difficult to see, and the front bumper 35 itself does not have high rigidity, so that it is difficult to secure sufficient rigidity in the mounted state.

Further, the lamp disclosed in Japanese Utility Model Laid-Open No. 4-99145 cannot be adjusted in optical axis because it is an integral lamp, and the mounting bracket is extended to be fixed to a frame member on the vehicle body side. However, since the lamp and the front bumper are only engaged with the clip, the rigidity of the front bumper cannot be increased with the mounting bracket, and the same problem occurs when the weight of the lamp is heavy. In order to increase the rigidity of the bumper, it is necessary to extend a separately provided stay and fix it to the frame member, which causes a problem that the number of assembling steps is increased.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, the present invention can adjust the optical axis of a lamp, and can properly illuminate the optical axis without blurring due to running vibration due to insufficient rigidity of the front bumper. It is an object of the present invention to provide an automobile lamp mounting structure that can also improve the mounting rigidity.

[0009]

According to the present invention, there is provided a lamp mounting structure for a vehicle, comprising a lamp having a lamp body supported by a lamp bracket so as to be able to swing up and down, and a lamp body having a lamp body formed in a front bumper. With it placed in
