A pair of engaging claws 10, 11 is formed on 2b.

As shown in FIG. 8, one end of the suspension arm (lower control arm) 12 is turned around a bolt 14 inserted into the bolt insertion holes 7, 8 of the suspension hanger bracket 1 and screwed to the nut 13. It is movably mounted. Although not shown, the other end of the suspension arm 12 is rotatably attached to a steering knuckle of a wheel. Then, as shown in FIG. 9, a bolt (clip) 15 is inserted into the engaging holes 4 and 5 of the bracket 1 while the engaging claws 10 and 11 of the cover 2 are click-engaged respectively. The cover 2 is attached to the hanger bracket 1 by screwing the nut 6 through the holes 9 and 3. As a result, the bracket 1 and the suspension arm attachment portion (specifically, the head 14a of the suspension arm supporting bolt 14 and the like) are covered and covered by the cover 2 to improve the appearance, and the suspension arm attachment portion Is trying to protect.

c. Problems to be Solved by the Invention However, in the conventional mounting structure as described above, it is necessary to align the engaging claws 10 and 11 of the cover 2 with the engaging holes 4 and 5 of the bracket 1. However, there is a problem that the work efficiency is poor. The bracket 1 has an engagement hole.
4, 5 and the bolt insertion hole 9 must be formed, and the dimensional accuracy between the holes 4, 5, 9 and the engagement claws 10, 11 of the cover 2 and the bolt insertion hole 3 is increased. Therefore, there is a disadvantage that the cost is increased. Further, since the engaging claws 10, 11 of the cover 2 are click-engaged with the engaging holes 4, 5 of the bracket 1, it is difficult to remove the cover 2 thereafter. 11 may be damaged.

The present invention has been made in order to solve such various problems, and an object of the present invention is to make it possible to mount the suspension cover with a simple operation with good work efficiency and at the same time. An object of the present invention is to provide a suspension cover mounting structure which can be easily removed without any trouble and at a low cost.
