ABSTRACT:
A one-way clutch includes an internal rotary member and an external rotary member, wherein a surface of the internal rotary member and a surface of the external rotary member define a clutch member space so that a width of the clutch member space varies from a wider portion to a narrower portion. A clutch member is disposed in the clutch member space so that (i) relative rotation between the internal rotary member and the external rotary member is inhibited when the clutch member is disposed in the narrower portion of the clutch member space; and (ii) relative rotation between the internal rotary member and the external rotary member is allowed when the clutch member is disposed in the wider portion of the clutch member space. A clutch member support is provided for supporting the clutch member within the clutch member space, and a coupling member is provided for increasing a coupling force between the clutch member support and one of the internal rotary member or external rotary member when the clutch rotates in a drive direction.
