Abstract
A one-way clutch for switching between a locking state in which an inner wheel and an outer wheel rotate synchronously, and a free state in which they rotate relative to each other. The one-way clutch includes a holding device having pockets for accommodating rollers provided at several positions on its circumference, and coil springs which are accommodated in each of the pockets in a compressed state for urging the rollers to a locking side of a pocket. The coil springs are in contact at points which span over 1/2 the width of the roller in the axial direction of the roller. As a result, a balanced urging force of the coil spring can be supplied to the roller, so that the rollers rotate smoothly and with a proper posture. Deflection of the coil springs is inhibited by alignment portions included at a surface of each pocket.
