Abstract
A one-way clutch is arranged so that a plurality of intermediate members, which are each retained in a cage, each wedge between inner and outer rings when the inner and outer rings relatively rotate in a locking direction and each rock opposite to the direction of the wedging when the inner and outer rings relatively rotate in an idling direction, are pressed in the direction of the wedging by spring members. In this one-way clutch, each spring member includes a pair of coil springs that are juxtaposed to align in an axial direction of the inner and outer rings, are retained at one ends thereof by the cage and resiliently contact at the other ends thereof with the intermediate member. The one ends of both the coil springs are connected together through a connecting portion. The coil springs and the connecting portion are formed of a single wire.
