The lower part 3a of the bumper garnish 3
As shown in FIGS. 3 and 4, four fastening pieces 8 extending toward the front bumper 1 in front of the vehicle body are arranged at intervals in the vehicle width direction. The bumper garnish 3 is attached to the front bumper 1 before being fixed to the vehicle body side by fastening these fastening pieces 8 to the lower portion of the front bumper 1 with the screw 9. In addition, the upper portion 3b near the center of the bumper garnish 3 is a connecting portion that is fastened together with the front bumper 1 to the bumper member 2b of the vehicle body front portion 2 using the bolt 10 and the nut 11. Reinforcing ribs 12 and 13 are provided in a lower portion of the front bumper 1 and a lower portion 3a of the bumper garnish 3, respectively.

In order to mount the front bumper 1 to the vehicle body front part 2 by the mounting structure according to the first embodiment of the present invention, first, while holding the bumper garnish 3 in the state shown in FIG. 3
The fastening piece 8a is fastened to the lower part of the front bumper 1 by a screw 9 and fixed. Next, holding the front bumper 1 and the bumper garnish 3 in the state shown in FIG.
The vehicle body mounting portion 4 provided in the lower portion 3a of the bumper garnish 3 is superimposed on the lower surface of the body panel 2a of the vehicle front portion 2, the clip 5 is inserted through the clip hole 6 and the mounting hole 7, and the superimposed portion is fastened. Fix by doing. In addition, the upper part 3b of the bumper garnish 3 is overlapped with the front bumper 1 on the bumper member 2b of the vehicle body front part 2, and this overlapped part is
And by fastening together with the nut 11,
The front bumper 1 is attached to the vehicle body front part 2 via the bumper garnish 3 (see FIGS. 3 and 4).

In the mounting structure according to the first embodiment of the present invention, the vehicle body mounting portion 4 of the front bumper 1 is provided in the lower portion 3a of the bumper garnish 3, and the front bumper 1
Since it is not provided on itself, it is possible to prevent the occurrence of sink marks that impair the appearance on the design surface of the bumper, and to simplify the bumper mold. In addition, since it is not necessary to make the body thinner in the vicinity of the vehicle body mounting portion 4 of the bumper garnish 3 in order to prevent sink marks, the vehicle body mounting portion 4 can have mounting rigidity. It can be firmly fixed to the body panel 2a of the vehicle body front part 2. Moreover, since the vehicle body mounting portion 4 of the present embodiment is integrated with the bumper garnish 2 which is a necessary bumper component in design, the above-described effect can be achieved without increasing the number of components.

FIG. 5 shows a second embodiment of the bumper mounting structure according to the present invention. As shown in FIG. 5, the rear bumper 21 according to the present embodiment is a synthetic resin bumper disposed on the rear portion 22 of the vehicle body, and has a size that can be disposed over substantially the entire width of the rear portion 22 of the vehicle. . On the left and right sides of the rear bumper 21 in the vehicle width direction, a rear bumper garnish 23, which is a separate bumper component, is attached by fitting or the like as a necessary accent in design. For this reason,
The rear bumper 21 is provided with a fitting hole 21a into which the bumper garnish 23 is fitted, so that the rear bumper 21 is attached to the rear bumper 21 before being fixed to the vehicle body side. The bumper garnish 23 is formed in a color different from that of the bumper main body due to the design of the rear bumper 21 and has an accent.
