Claims (1)

[Claims for Utility Model Registration] A plurality of rollers are interposed between a first ring and a second ring that are arranged concentrically, and the first ring and the second ring are relatively In a one-way clutch that can be rotated in the position direction but not in the other direction, a circumferential surface of either the first or second ring is provided with a ring of the ring. A plurality of roller housing grooves extending along the entire length in the axial direction are spaced apart in the circumferential direction of the ring,
Each roller housing groove has a cam surface formed such that the distance from the other circumferential surface gradually changes in the circumferential direction;
It has at least an engaging surface that is continuous with the cam surface and extends substantially in the radial direction of the ring, and each of the rollers is accommodated in each of the roller accommodating grooves, and each roller is disposed behind the cam surface in the roller accommodating groove. is urged in a direction to engage the cam surface and the circumferential surface by a spring member disposed in the roller, and the roller accommodated in the roller accommodation groove is movable in the circumferential direction of the one ring. It has a roller holding member for holding one of the rollers, and the roller holding member is in close contact with one end surface of the one ring over its entire circumference and is immovably immovable in the axial and radial directions. a first ring member that forms a side wall of each of the roller housing grooves; and a first ring member that is tightly attached to the other end surface of the one ring over its entire circumference and in a relatively immovable manner in the axial and radial directions and forms the other side wall of each of the roller housing grooves. a second ring member formed integrally with one of the two ring members, extending from the spring member and the other ring in the axial direction of the one ring and engaging the engagement surface; and a connecting portion whose tip is locked to the other ring member, and the connecting portion connects the first and second ring members to each other, and the roller holding member is connected to the one ring member. The roller holding member is combined with the one ring between the first and second ring portions of the roller holding member and both end surfaces of the roller. 1. A one-way clutch, characterized in that the one-way clutch is provided with means for engaging the roller and preventing the roller from falling off when the clutch is turned.
