PURPOSE:To facilitate connection/disconnection of a fixed flange to/from a connecting shaft and make the shaft center with the connecting shaft in the case of connection. CONSTITUTION:Areas in the vicinity of both ends of a fitting face 15 are pressed against an outer circumferencial face 31a so as to fix a fixed flange to an output shaft 31. The fitting face 15 is formed in such a recessed state of gradually deepening the recess from the areas in the vicinity of both ends toward the center in the unfitted state and a bolt in inserted into an penetration hole 12 for screwing its spirally engraved part into a screw hole 13 by a prescribed amount so that the flange main body 1 is deformed to narrow the opening width of a groove 11 and then the minimum bore of the fitting face 15 is enlarged. |
