Claims

[Scope of utility model registration request]

A holding cylinder whose inner peripheral surface is a cylindrical surface, an outer cylinder having a cam surface on its inner peripheral surface and fitted and fixed inside the holding cylinder, and inserted into the inside of this outer cylinder concentrically with this outer cylinder. an inner member having at least a cylindrical outer circumferential surface; a plurality of rollers inserted into a gap between the outer circumferential surface of the inner member and the inner circumferential surface of the outer cylinder; and an inner side of the outer cylinder. A retainer is fitted in such a manner that it cannot rotate with respect to the outer cylinder and holds the plurality of rollers, and a retainer is provided between the retainer and each of the rollers and presses each roller in the same circumferential direction. a spring; an outer ring having an outer ring raceway on the inner circumferential surface; an outer ring fitted and fixed in a portion of the holding cylinder that is disengaged from the part where the outer cylinder is fitted and fixed; and an inner ring raceway on the outer circumferential surface. A roller clutch comprising an inner ring and a plurality of balls which are provided between the outer ring raceway and the inner ring raceway and which are combined with the outer ring and the inner ring to form a ball bearing.
