Therefore, conventionally, in order to obtain the bumper performance in such a case, for example, as shown in FIG. 7B, appropriate reinforcement is set in the bumper. That is,
When the reinforce 4 as shown in FIG. 7B is provided, the reinforce 4 is assembled from the vehicle body via the bumper arm. This Reinforce 4
Is not related to the bumper cover 1 in terms of the connection structure, so that the vertical space in the bumper may be filled with the beads 5 made of polypropylene.

[0004]

However, in the lamp mounting structure of the above-mentioned conventional front bumper, if the performance is not satisfied at a minute level, a drastic structural change must be made. In order to secure the dimensions, there was a case where the design had to be changed. Further, when the rigidity is to be increased only by the bumper cover 1, it is substantially difficult to increase the rigidity due to a problem of appearance or so-called sink during molding. That is, there is a problem that the setting of the rib or the increase of the thickness cannot be performed.

In view of the above, this invention provides a lamp mounting structure for a front bumper that can easily and surely ensure the bumper performance by effectively utilizing the front turn lamp itself, particularly in a vehicle with a small bumper allowance. It is intended to be.

[0006]

According to the lamp mounting structure of the front bumper of the present invention, a housing of a front turn lamp is fitted to a window formed in a bumper cover. And the reinforcing member is fixed by a locking piece provided on the bumper cover.

[0007] A notch or a thin-walled portion is particularly provided at a joint between the housing and the reinforcing member.

Further, the housing has a spare mounting bracket.

[0009]

According to the present invention, the reinforcing member attached to the housing of the front turn lamp substantially acts as a reinforce, thereby increasing the rigidity of the bumper. In this case, the reinforcing member is formed on the housing itself, and the reinforcing member is assembled to the bumper cover, so that the bumper allowance can be reduced.

Further, the reinforcing member is attached to the housing, but a notch or a thin portion is provided at a connection portion between the two, so that when an excessive load input acts on the front turn lamp, the notch or the thin portion is provided. Is broken and the front turn lamp is separated from the bumper cover. Thus, it is possible to effectively prevent the front turn lamp from being damaged due to excessive load input.

Even if the front turn lamp is detached from the bumper cover as described above, the front turn lamp can be easily re-assembled via the spare mounting bracket provided on the housing.
