Thereafter, as shown in FIGS. 2 and 3, openings 9b and 9c are provided on the side surface 9 of the vertical wall member 8, and the opening 9b is formed.
From the outside of the vertical wall member 8 in the vehicle width direction, the bolt 50 is inserted and provided on the L2 surface of the leg portion 14 configured in an L shape with the L1 surface and the L2 surface as shown in FIG. 2B. Hole 14b
Since the grill guard 10 can be attached by screwing it onto the weld nut 40N provided on the upper bracket 40 via the above, it is possible to perform the above-described positioning to fastening easily.

As described above with reference to FIG. 1, after the grill guard 10 is attached to the bumper body 6 as described above, it may be attached to the front end portions 21 of the side members 20a and 20b of the vehicle body 4, or the bumper body 6 is attached. The grill guard 10 can be easily attached and detached as described above even when the grill guard 10 is attached to the vehicle body 4 and the side bumper 16 is not provided. Further, even in the assembly line of the vehicle body 4, the grill guard mounting structure of the present invention can be used to easily perform positioning and maintain the state, so that the grill guard 10 can be easily assembled.

The grill guard 10 of the present invention, which is made of resin, metal, or made of resin and metal, can achieve the same effect as the above, but in the case of the present embodiment, it is made of resin. In the injection molding, for example, the guide portion necessary for gradually supplying the resin from both ends of the mold of the required grill guard 10 is configured to be the leg portion 14 of the grill guard. It is possible to manufacture at low cost without the need to specially form the leg portion 14 described above.

The method of molding the grill guard 14 with the resin is not limited to injection molding.
For example, blow molding may be used, and the same effect as the above can be obtained by using the portion generated by the resin supply passage or the like formed during molding as the leg portion 14. In addition, in the mounting structure of the grill guard 10 of the present invention, the leg portion 14 of the grill guard 10 is provided with the opening 6p in which the spacer 7 of the elastic member on the upper surface 6b of the bumper body 6 is mounted, the upper mounting portion Y1, and the lower mounting portion Y2. Even with the point support, in addition to the above-mentioned effects, the mounting position can be securely held firmly.

Further, although the leg portion 14 is fastened by the single bolt 50, it may be fastened by a plurality of bolts if necessary. Further, since the grill guard mounting structure of the present invention is mounted in the front-rear direction of the vehicle body 4 of the bumper body 6, the leg portions 14 of the grill guard 10 can be attached to the bumper body 6 without increasing the length of the vehicle. Since it is mounted inside and is mounted on the bumper body 6 from the vehicle width direction by the mounting tool T such as bolts and clips, the work of attaching and detaching the grill guard 10 is easy and easy, and the side bumper 16 allows the bumper to be attached and removed. Since the left and right ends of the main body 6 are covered, the attachments T and the attachments T such as bolts do not appear on the surface of the vehicle, and the appearance is improved in terms of design and productivity can be improved.

Further, in the above embodiment, the vertical wall member 8 is provided at the opening end portions 6h at both ends of the bumper body 6, but the present invention is not limited to this. For example, the opening 6p in FIG. The vertical wall member 8 may be disposed inside the open end portions 6h at both ends on the left side, and the upper and lower mounting portions 40, 44 may be disposed on the left side surface outside the vertical wall member 8. Good.

In this case, other parts in the vicinity of the vertical wall member 8 may be appropriately moved to the related positions and applied as necessary.
