PROBLEM TO BE SOLVED: To prevent deflection a coil spring, bring a coil spring into an immobile state, and to stabilize operation. SOLUTION: A one-way clutch A switches two inner and outer annular bodies 3 and 4, concentrically disposed, into a lock state, wherein the annular bodies are synchronously rotated, and a free state wherein the annular bodies are caused to effect relative rotation. The one-way clutch comprises a holder 2 to have pocket 6 wherein rollers 1 are peripherally rollablly contained in a plurality of spots on a periphery; and a coil spring 5 contained in a compressed state in the pocket 6 and energizing in a rebounding state the roller 1 to the lock side through a stretch restoration force. A protrusion 8 to receive the inner periphery of the coil spring 5 is formed on the inner peripheral wall of the pocket 6 of the holder 2. This constitution prevents deflection of the coil spring 5 and fixes the coil spring 6 in a home position. |
