BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a bumper side, and more particularly to a structure in which the bumper side is mounted on a fender by a set plate.

[0002]

2. Description of the Related Art Conventionally, as an automobile front bumper, for example, as shown in Japanese Utility Model Laid-Open Publication No. 2-81257, an upper edge of a bumper side is formed along a lower edge of a cornering lamp. Further, there is a known bumper side in which a rear edge portion is brought into contact with a front edge portion of a fender. The rear edge of the bumper side is attached to the front edge of the fender by means such as bolting. An example of a mounting structure for this portion is one using a set plate. Specifically, a vertical flange formed by bending the rear end of the bumper side inward is formed on the bumper side, and a bolt insertion hole is provided at a plurality of positions of the vertical flange. Abut the set plate on which the bolt is erected at the position. In this state, a plurality of bolts protrude rearward from the vertical flange. On the other hand, a flange formed by bending the front end of the fender inward is formed, and a plurality of bolt insertion holes corresponding to the projecting positions of the bolts are provided in the flange. And
When attaching the bumper side to the fender, the vertical flange of the bumper side is overlapped with the flange of the fender, and the bolt is inserted into the bolt insertion hole of the fender flange. Enter. In this way, the bumper side is bolted with the fender abutting.

[0003]

However, in recent years, due to design requirements around the headlights of automobiles, the lower edge of the rear end of the cornering lamp has been inclined upward toward the rear of the vehicle body. Things are heavily used. However, in a vehicle provided with a cornering ramp having such a shape, the upper edge around the rear end of the bumper side is inclined along the lower edge of the cornering ramp. And the butted portion becomes an acute angle. Therefore, when the above-described set plate is to be brought into contact with the vertical flange of the bumper side from the front side, the upper edge of the set plate interferes with the inclined portion, and the set plate is displaced. A situation arises in which it cannot be mounted on the bumper side. In order to avoid this interference, it is conceivable to set the upper end position of the set plate to a lower position. The assembling strength of the upper end of the butted part of the fender is reduced, and it is difficult to maintain the flush state between the bumper side and the fender, leading to deterioration of appearance.

The present invention has been made in view of these points, and has a bumper side mounting structure capable of mounting a set plate while ensuring the appearance around the bumper side. The purpose is to obtain.

[0005]

In order to achieve the above object, the present invention is to insert a set plate from a direction which does not interfere with an inclined portion of a bumper side. It has a holding function to the side. Specifically, a fender having a mounting flange at the front end, a bumper side having a vertical flange superimposed on the mounting flange of the fender and having an inclined flange connected to the vertical flange at an acute angle,
A set plate assembled to the vertical flange and having a plurality of bolts extending toward the mounting flange of the fender, the bolt of the set plate being fastened to the mounting flange of the fender, It is assumed that the bumper side is attached to the fender. A plurality of bolt insertion portions penetrating through the vertical flange are arranged in the vertical flange in the up-down direction of the vertical flange, and the bolt insertion portions except those at the lowermost end are connected to the set plate. The bolt is formed open so that it can be inserted from the width direction of the vertical flange, and at least one of the bolt insertion portions that is close to the inclined flange has an open dimension smaller than the diameter of the base end of the bolt. . On the other hand, at least one of the other bolt insertion portions is formed with a locking portion extending parallel to the bolt insertion direction of the set plate, and is locked to the set plate at the locking portion. Thus, a locking piece for suppressing relative movement of the set plate and the vertical flange in the front-rear direction is provided.

[0006]

According to the present invention, when assembling the set plate to the vertical flange of the bumper side, the bolts of the set plate except for the lowermost one are inserted from the width direction of the vertical flange. To assemble. In other words, the set plate does not interfere with the inclined flange during the operation of assembling the set plate, and the assembling operation can be easily performed. Further, since it is not necessary to set the upper end of the set plate at a lower position, the projecting position of the uppermost bolt can be set at a higher position, and the mounting strength to the fender at the upper end of the bumper side can be improved. When the set plate is mounted on the vertical flange in this manner, the bolt of the set plate is prevented from being pulled out of the bolt insertion portion at the bolt insertion portion adjacent to the inclined flange. Further, the locking piece of the set plate is locked to the locking portion so that the set plate does not come off the vertical flange in the front-rear direction. Therefore,
In this state, the set plate is mounted on the vertical flange with high strength, and is prevented from easily coming off.
