Claims

[Scope of utility model registration request]

A cylindrical outer ring having a cam and a surface on the inner circumferential surface, a shaft with a circular cross section inserted concentrically with the outer ring inside the outer ring, and a shaft between the outer circumferential surface and the inner circumferential surface of the outer ring. Multiple rollers inserted into the gap,
A plurality of pillars are provided on one side of a single circular rim, parallel to each other and equally spaced, and the pocket is fitted inside the outer ring so that it cannot rotate with respect to the outer ring, and is provided between adjacent pillars. A rotor clutch consisting of a retainer for holding the plurality of rollers inside the rotor clutch, and a spring provided between the retainer and each of the rollers to press in the same circumferential direction of each roller. , a locking hole that opens toward the tip side of each column on the inside of each of the columns, and a notch-shaped recess that connects the locking hole with the same circumferential side of each column on the end surface of each column; At the same time, by folding and forming the spring material, one piece of the spring formed into a substantially U-shape is inserted into the locking hole formed in each of the pillars, and the other piece of the spring is inserted into the locking hole formed in each of the pillars. A roller clutch characterized by being pressed against the outer peripheral surface of a roller held inside a pocket.
