The hand member 50 fixed to the crank pin 48 (see Fig. 5) is formed by laminating two semicircular plates 51 and 52, which are formed separately and have a thickness of about 3 mm. . One plate body 51, which is the main body of the semicircular part, has a through hole 55 in the center extending on the opposite side from the circular arc, through which the crank pin 48 is inserted. In order to overlap with the plate 51, its shape is the same as that of the plate 51, but its center portion is removed so that the through hole 55 can be seen. On the other hand, the arc portion 53 is formed by arc-shaped thin plates 5.3a, 53.
It is formed by laminating b + . Therefore, as a means for fixing the arcuate member 53 to the hand inner member 50, holes are bored through each of the thin plates 53a, 53b, . . . to the hand inner member 51, 52, and rivets 5
