DEVICE AND METHOD FOR ASSEMBLING RETAINER AND COTTER

摘要

The large-diameter side end surface (104a) of a cotter (104) can be supported by a cotter holder (32) from the lower side by inserting a shaft member (102) into the inner periphery of the cotter (104) from a position above the cotter (104). In this state, the projecting part (104b) of the cotter (104) and the annular groove (102a) of the shaft member (102) are fitted to each other, and the cotter (104) and a retainer (103) are taper-fitted to each other whereby the cotter does not become unstable, and the retainer (103) and the cotter (104) can be accurately assembled to the shaft member (102).
