Claims

[Claims for Utility Model Registration] A shell having a plurality of cam surfaces on its inner circumferential surface that form a wedge-shaped space that is symmetrical in both forward and reverse rotational directions with respect to the outer circumferential surface of a central rotating body; a retainer having a plurality of roller pockets corresponding to positions on the cam surface and fitted and fixed in the shell; a plurality of rollers rotatably held in each of the roller pockets; and a retainer provided in each roller pocket. a bidirectional rotating clutch having a spring for biasing each roller toward the lock side of each wedge-shaped space, the clutch having shafts at several locations around the circumference of the retainer so as to pass through roller pockets corresponding to at least one of the wedge-shaped spaces; a hole provided along the direction; and a hole provided on the side of the cage so that the roller can be inserted into and removed from the pocket through the hole, and when inserted, the roller is moved to the free side in one wedge-shaped space. A bidirectional rotating clutch characterized by having a forced displacement pin and.
