Claims

[Scope of utility model registration request]

A cam body that is coupled to one side of the rotating body and has a plurality of chordwise cam surfaces formed on its outer peripheral surface, a plurality of cylindrical rollers that are rollably arranged on each cam surface of the cam body, and a retainer disposed on the outer periphery so as to be movable in the circumferential direction and holding the cylindrical rollers so that they can roll together; and a retainer fixed to both end surfaces of the cam body to move the cylindrical rollers and the retainer in the circumferential direction of the cam body. A coupling device comprising a retainer guide for holding the cam body so that another rotating body is loosely fitted to the outer periphery of the cam body including the cylindrical rollers.
