As shown in FIGS. 4 and 5, the lowermost grill element 80 of the radiator grille 4 is provided with a positioning pin 82 protruding downward as a grill side positioning member. 82 and the positioning hole 78 are removably engaged with each other, so that the radiator grille 4
The relative positioning of the bumper front 14 and the bumper front 14 in the longitudinal direction of the vehicle is determined. In the embodiment, the lower end 84 of the radiator grille 4 and the upper end 8 of the bumper front 14 are positioned in the longitudinal direction of the vehicle as described above.
The mounting positions of the positioning hole 78 and the positioning pin 82 are set such that both the outer surfaces 88 and 90 form a continuous and integral inclined outer surface state.

The grill element 92 at the upper end of the radiator grill 4 is fixed to a bracket 96 of a radiator core support 94 by bolts, as shown in FIG.

Next, the operation of the embodiment will be explained.

The assembly work of the resin bumper 2 and the radiator grille 4 will be described below according to the work procedure.

Fender 6 arch 18 and bumper side 16
The bumper side 16 is attached to the fender 6 by aligning the end edges 20 of the bumper side 16 and the outer surface 40 of the bumper side 16 with the outer surface 38 of the fender 6.

Bumper front lower part 4 of bumper front 14
4 to the reinforcement 42.

Bumper front upper part 5 of bumper front 14
0 and retainer 60 are attached to the reinforcement bracket 52. In this case, the mounting position due to the dimensional error in the longitudinal direction of the resin bumper 2 is adjusted and absorbed by the long holes 62, 64, and 66, and the resin bumper 2 is mounted.

At this time, the positioning locking piece 7 of the positioning bracket 68 fixed to the retainer 60
4 is brought into contact with the end surface 70 of the bumper front upper part 50, and the bolt 54 is tightened.

Place the positioning pin 82 on the positioning bracket 6
8 into the positioning holes 78, and bolt the grill element 92 at the upper end to the bracket 96 of the radiator core support 94 to attach the radiator grill 4.

After completing the above operations, the resin bumper 2 and the radiator grille 4 are assembled.

In this installation work, by installing the bumper side 16 as described above, the fender 6
The edge 20 of the bumper side 16 matches the arch 18 of the bumper side 16, and the outer surface 40 of the bumper side 16 matches the outer surface 38 of the fender 6, giving the fender 6 and bumper side 16 a sense of unity in appearance. It can be made to stand. However, since the resin bumper 2 is large and integral, it tends to have errors in dimensional accuracy and is also subject to thermal deformation. Therefore, when the end edge portion 20 of the bumper side 16 is fixed, a positional shift occurs on the bumper front 14 side in the front-rear direction.

By installing the bumper front 14 in the manner described above, the relative positional relationship with the radiator grille 4 can be maintained in the fixed relationship just by assembling without adjusting the installation position. The outer surface 90 of the bumper front 14 coincides with the surface 88, so that the radiator grille 4 and the bumper front 14 can have a sense of unity in appearance.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and any design changes or the like that do not depart from the gist of the present invention are included in the present invention. It will be done.

For example, in the example, an example was shown in which a bracket and pin with holes were used to position the bumper front and front grille in the longitudinal direction of the vehicle. Even if a bracket is used, other
A member or the like that can regulate the positional relationship between the two in the longitudinal direction of the vehicle may be used.

Further, in the embodiment, the mounting structure is such that the fender and the bumper side, and the radiator grille and the bumper front have a sense of unity in appearance, but the mounting structure is not necessarily limited to this structure.

Further, in the embodiment, a radiator grill is shown as the front grill, but the present invention is not limited to a radiator grill as long as it is a grill disposed on the front of the vehicle.

Furthermore, the retainer and positioning bracket of the embodiment may be integrated.

(Effects of the Invention) As explained above, in the automobile bumper mounting structure of the present invention, the bumper front can be attached to the rainforest by aligning the edge of the bumper side with the arch of the fender. Even if the positioning member is misaligned in the front-rear direction with respect to the bumper front, the positioning member will be positioned and installed in the front-rear direction with respect to the bumper front, and the front grill will be fixed in the front-rear direction with respect to the positioning member by the locking portion. Since the bumper front and the front grill can be attached without moving, the relative positional relationship between the bumper front and the front grill can be maintained constant without adjusting the attachment positions.
