DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a grill guard as a fitting for a four-wheeled vehicle.

[0002]

2. Description of the Related Art Conventionally, a grill guard for protecting a front grill and the like from obstacles is mounted on a front portion of a vehicle body as a fitting. As a mounting structure of this type of grill guard, for example, there is a structure as shown in FIG. 5. The grill guard 51 is mounted on left and right side frames 53 and 54 via a pair of right and left mounting stays 52. Then, the grill guard 51 is fixed to the side frame 53 by the fastening bolt 55 and the nut 56.
Since the grill guard 51 is generally heavy, it is mounted from the front of the vehicle body (in the direction of the arrow a in FIG. 5) using a mounting jig such as a balancer.

[0003]

However, in the conventional mounting structure described above, the use of a mounting jig such as a balancer is indispensable for mounting the heavy grill guard 51 to the side frames 53 and 54. Therefore, there is a problem that the equipment becomes large and the jig cost increases. Further, since the side frames 53 and 54 have a structure in which the pitch L between the left and right is difficult to appear due to distortion due to welding of other parts, when the assembling work is performed from the front of the vehicle body, the mounting stay 5
2 could not enter between the side frames 53 and 54, resulting in a grill guard 51 that could not be assembled.

Further, in the conventional mounting structure, even if the balancer or the like is temporarily held, it is difficult to perform the temporary tightening with the tightening bolt 55, and the tightening direction of the tightening bolt 55 (see FIG. Since the left and right directions of arrows b and c in FIG. 5 are different from each other, it is necessary to change the tightening tool. Therefore, it is difficult to quickly attach the grill guard 51 to the side frames 53 and 54, and the workability is poor.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and its object is to make it possible to easily assemble even if there is an error in the pitch between a pair of right and left frames and to temporarily hold the frame before tightening. It is another object of the present invention to provide a grill guard mounting structure which makes it possible to eliminate the necessity of changing and holding a tightening tool and improving workability.

[0006]

In order to solve the problems of the prior art, according to the present invention, a pair of left and right grill guard stays having one end fixed to a grill guard, and a frame having one end on both right and left sides are provided. A pair of left and right connecting stays, the other ends of which are arranged so as to protrude more toward the grill guard side than the frame, a stud bolt is provided on one grill guard stay, and a fixing nut is provided on the other grill guard stay. And a pair of left and right grill guard stays are arranged along the other end of the connecting stay from the vehicle width direction, and a nut is screwed into the stud bolt, and the fixing is performed. A tightening bolt is screwed into the nut, and the other end of the pair of left and right grill guard stays and the other end of the pair of left and right connection stays are tightened. By fixing Te, it is attached to the grille guard to the left and right sides of the frame.

[0007]

In the grill guard mounting structure according to the present invention, the grill guard is assembled from the vehicle width direction and the tightening bolts and nuts are tightened from the same direction on both the left and right sides. Even if there is an error in the pitch, the grill guard can be easily assembled, and workability is improved. In the mounting structure of the present invention,
Since one grill guard stay is provided with stud bolts and the other grill guard stay is provided with engaging claws, the use of these stud bolts and engaging claws enables the tightening before tightening without using a holding jig. In this case, the grill guard can be temporarily held.
