Therefore, the shape stability of the lower end of the side wall portion 322 can be improved. Therefore, it is possible to further prevent foreign matter from entering through the opening H formed at the side end of the cowl grille 22.

Further, as shown in FIGS. 4 and 6, on the rear side of the molding part 32, vertical ribs 325 and 326 are provided that extend in the vertical direction from the upper wall part 324 to the lower wall part 323. Since the horizontal rib 327 is provided to connect the intermediate portion of the molded portion 325 and the vertical ribs 325 and 326, the shape stability of the molded portion 32 having the side wall portion 322 can be improved. Therefore, the side wall portion 322 that improves load absorption performance at the side end portion of the cowl grille 22 can more reliably prevent foreign matter from entering.

Further, as shown in FIGS. 4 and 5, an extending wall portion 249 extending rearward from the lower end is provided at the side end of the front portion 24 of the cowl grille 22. Since the lower end and the lower end of the side surface portion 248 of the cowl grille 22 are attached, it is possible to improve the manageability of the gap created between the side wall portion 322 of the molded part 32 and the side surface portion 248 of the cowl grille 22.
