Thereby, the front air dam skirt 4 can be temporarily fixed to the front bumper 2.
Then, the screw 5 is passed through the screw hole 42a of the front air dam skirt 4 and the screw fixing portion 24 of the front bumper 2 from below the vehicle, and the screw 5 is tightened and fixed.
[0012]
In the present embodiment, the position of the front air dam skirt 4 with respect to the front bumper 2 in the vehicle front-rear direction F and R can be regulated by the engagement of the projection 25 of the front bumper 2 with the square hole 43a of the front air dam skirt 4. The front air dam skirt 4 does not deform as indicated by the line Z in FIG. Therefore, the curvature of the front air dam skirt 4 can be easily adjusted to the curvature of the front bumper 2 without increasing the number of screw fastening locations.
Further, since the front air dam skirt 4 can be temporarily fixed to the front bumper 2 before being tightened with the screw 5, workability can be improved.
[0013]
In the present embodiment, the projection 25 is provided on the front bumper 2, and the square hole 43 a is provided on the front air dam skirt 4. However, the present invention is not limited to this, and the lower surface 6 a of the front bumper 6 is provided as shown in FIG. A square hole 6b may be provided, and a protrusion 7b may be provided on the flange 7a of the front air dam skirt 7. In this case, a slope 7c which becomes lower toward the front F of the vehicle is formed in the front F of the projection 7b.
