A one-way clutch is provided which has improved compactness. The one-way clutch comprises an inner member, an outer ring relatively rotatably mounted on the inner member, a rolling element mounted between the inner member and the outer ring, and a spring member for biasing the rolling element in one direction. A rolling element receiving portion having a predetermined wedge angle and a spring receiving portion communicating with the rolling element receiving portion are provided between the inner member and the outer ring. The spring member is received in the spring receiving portion, and the rolling element is received in the rolling element receiving portion and biased by the spring member toward the narrow side of the rolling element receiving portion. The inner member has a semi-columnar portion, which forms the rolling element receiving portion and the spring receiving portion.
