The flange 20F is inserted into a gap G1 extending between the first rib 44 and the wall 43. Each first rib 44 includes a front end 44E extending frontward, and the front end 44E of the first rib 44 is in contact with the flange 20F. Due to this, the position of the resin fender 20 in the vehicle front-rear direction (right-left direction in FIG. 5) can be held.

Similarly, the flange 30F is inserted into a gap G2 extending between the second rib 45 and the wall 43. Each second rib 45 includes a rear end 45E extending rearward, and the rear end 45E of the second rib 45 is in contact with the flange 30F. Due to this, the position of the bumper 30 in the vehicle front-rear direction can be held.

The wall 43 is disposed between the flange 20F and the flange 30F. The wall 43 can prevent the flange 20F and the flange 30F from directly interfering with each other.

As shown in FIGS. 4 and 5, the retainer 40 comprises a surface 40S1 disposed rearward of the groove 40T and a surface 40S2 disposed frontward of the groove 40T. A distance D1 between the surface 40S1 and a rear surface of the resin fender 20 is substantially constant. Contrary to this, the surface 40S2 is angled such that a distance between the surface 40S2 and a rear surface of the bumper 30 is at a longest distance D2max at an end of the surface 40S2 disposed frontward and at a shortest distance D2min at an end of the surface 40S2 disposed rearward. In other words, the surface 40S2 is angled such that the surface 40S2 protrudes outward at a greater degree toward a rear side of the surface 40S2.

(Mounting Structure)

A process of mounting the retainer 40, the resin fender 20, and the bumper 30 to the front fender panel 10 will be described. Firstly, the retainer 40 is mounted on the front fender panel 10. Specifically, the clip 49 is inserted into a clip hole (not shown) arranged on the front fender panel 10. Further, the retainer 40 is screwed onto the front fender panel 10 through the screw holes 48.

Secondly, the resin fender 20 is mounted. Specifically, as shown in an arrow Y1 in FIGS. 3 to 5, the resin fender 20 is brought close to the retainer 40 along a direction substantially perpendicular to the surface 40S1 of the retainer 40. The first fixing pawls 41 are made to engage into the holes 21 of the flange 20F. Then, by using a clip or the like (not shown), the resin fender 20 is fixed to the front fender panel 10.

Thirdly, the bumper 30 is mounted. Specifically, as shown by an arrow Y2 in FIGS. 3 to 5, the bumper 30 is moved in parallel from the vehicle front side to the vehicle rear side. At this occasion, a tip 30FE of the flange 30F on a vehicle inner side moves in the arrow Y2 direction while sliding on the surface 40S2. Due to this, the bumper 30 can be brought close to the retainer 40. while allowing the bumper end 30E to be elastically deforming such that the bumper end 30E extends outward in the vehicle width direction. Once the flange 30F has reached the groove 40T, the flange 30F is engaged with the groove 40T by self-alignment by elastic force exerted by the bumper 30 returning to its original shape. That is, the surface 40S2 functions as a guide surface for inserting the flange 30F into the groove 40T. Due to this, the bumper 30 can be smoothly incorporated.

For example, if the bumper 30 is assembled with the retainer 40 along the substantially-perpendicular direction (arrow Y1 direction), there may be a risk where the bumper 30 will come into contact with the resin fender end 20E of the resin fender 20 that has already been mounted, as a result of which the resin fender end 20E may be scratched. According to the art disclosed herein, the bumper 30 can be mounted from the front of the vehicle (arrow Y2 direction), by using the surface 40S2 as a guide surface. Thus, the resin fender end 20E can be prevented from touching the bumper end 30E.

The surface 40S1 does not need to function as a guide surface, and therefore the surface 40S1 and the rear surface of the resin fender 20 can be made substantially parallel to each other. Thus, the surface 40S1 can be allowed to function as a reinforcement for the resin fender 20. Panel rigidity of the resin fender 20 can be ensured.

(Effects)

As a comparative example, a case where the resin fender end 20E is not held by a retainer will be considered. In this case, a position of the resin fender end 20E is determined indirectly by a clip for example (not shown) which retains the resin fender 20 at a position other than the resin fender end 20E. In the art disclosed herein, the retainer 40 is used to fix the resin fender end 20E and the bumper end 30E. Positions of the resin fender end 20E and the bumper end 30E can be determined directly by the retainer 40. Compared to the comparative example, accuracy of holding the positions of the resin fender end 20E and the bumper end 30E can be enhanced. As a result of this, the gap GP between the resin fender end 20E and the bumper end 30E (see FIG. 5) can be made small.

There may be a case where a retainer is used to fix a rear end of a bumper to a front fender panel. In the art disclosed herein, the retainer for fixing the end of the bumper mentioned here can also be used to serve as a retainer for fixing an end of an external fender. Additional component is not necessary, and thus cost increase can be suppressed.
