Claims

[Scope of utility model registration request]

The cylindrical outer ring has a plurality of groove-shaped recesses extending in the width direction and forming cam surfaces formed on the inner peripheral surface in the circumferential direction, and the outer ring has an outer diameter smaller than the inner diameter of the outer ring. A shaft with a circular cross section that is inserted inside the outer ring concentrically with the outer ring, and the largest part of this gap that is inserted into the gap between the outer peripheral surface of this shaft and the inner peripheral surface of the outer ring and is aligned with the recess. a plurality of rollers having an outer diameter smaller than the dimension of the above-mentioned recess and larger than the dimension of the smallest part of the gap removed from the recess; a retainer for holding the roller in a position where it can be freely aligned with the recess in the gap;
In a roller clutch consisting of a spring that presses each of the rollers in the same circumferential direction, a protrusion having a height greater than the thickness of the outer ring is formed on the outer peripheral surface of the end of the retainer, and the outer ring A roller clutch characterized in that the tip of the protruding portion protruding from the outer circumferential surface of the roller clutch can be freely fitted and locked into a locking recess formed on the inner circumferential surface of the housing portion of the housing into which the outer ring is fitted.
