On the other hand, on the back side of the upper edge of the front bumper 1, there are provided ribs 12 bent toward the rear of the vehicle body with respect to the front bumper main body 1a. Each is provided. That is, by providing a rib portion near the left and right center of the front bumper 1 with respect to the notch groove 13 (a left rib portion of the notch groove 13 in FIG. 3), this rib portion and the front bumper main body 1a are substantially provided. And a concave portion for inserting the flange piece is formed. The notch groove 13 is opened at the tip end surface 12a of the rib 12, and is formed so as to extend substantially along the vehicle longitudinal direction. Thus, the insertion engaging portion 14 including the flange piece 11 and the cutout groove 13 is formed at the parting portion of the fender 3 and the front bumper 1 (see FIG. 3).
[0012]
When assembling the front part of the vehicle body, first, the fender 3 is mounted on the vehicle body, and after the fender 3 is mounted, the front bumper 1 is mounted on the vehicle body. More specifically, first, the fender 3 is assembled at a predetermined position on the side surface of the vehicle body, and the mounting pieces 4 and 5 of the fender 3 are fastened and fixed to the vehicle body by screws. As a result, the flange piece 11 of the fender 3 is arranged substantially along the vehicle body front-rear direction with the flange piece 11 protruding forward from the mounting piece 5 as shown in FIG.
