する。FIG. 5 shows a case where a reinforcing plate having a shape different from that in FIG. The structure is the same as that shown in FIG. 2, and the structure of the positioning pin 3 that can be fitted into the through hole 6 formed at the other end B of the reinforcing plate 7 is also the same as that shown in FIG. 2, as shown in FIG. However, since the other end B of the reinforcing plate 7 only contacts the shoulder 3a of the positioning pin 3, the holding of the reinforcing plate 7 becomes unstable. Moko,
A part of one side end C between both ends of the reinforcing plate 7 is bent toward the bottom surface of the suspension arm 1 to form a bent portion 8.
つぎに、補強板７を位置決めする場合について述べると
