Embodiments of the present invention will be specifically described below with reference to the drawings.
The centrifugal clutch assembly device according to this embodiment is for assembling a centrifugal clutch in which a weight W is swingably attached to a shaft member L formed on a support plate F, as shown in FIGS. 21 to 23. As shown in FIG. 1, this device includes a weight sorting section A, a spring assembly section B, a support plate assembly section C, a weight assembly section D, and a side plate assembly section E. ing.

As shown in FIGS. 21 to 23, the centrifugal clutch applied to this embodiment includes a support plate F to which a plurality of (three in this embodiment) shaft members L are attached, and each shaft member of the support plate F. A plurality of (three in this embodiment) weights W are inserted through and attached to L, a spring S is assembled by connecting adjacent weights W, and a spring S is assembled to the convex portion Fb of the support plate F. A side plate G is attached to the tip end of the shaft member L, and an E ring e is provided to prevent the weight W attached to the shaft member L from coming off.

The support plate F is made of a metal annular member in which a plurality of (three in this embodiment) insertion holes Fa and convex portions Fb are formed in the circumferential direction, and a shaft member L is inserted into each insertion hole Fa. It is inserted through and fixed by caulking, and a damper b is attached to each convex portion Fb. The shaft member L is made of a shaft-like member having a flange La formed at a predetermined position, and the damper b is made of a rubber material or an elastic body formed into a cylindrical shape.

The weight W is made of a metal member set to a predetermined weight, and has a clutch shoe Wa formed on its outer circumferential surface, an insertion hole Wb through which the shaft member L is inserted, and an end portion Sa of the spring S through which the weight W is inserted.
