ABSTRACT:
A one-way clutch includes an outer member with inner teeth; an inner member rotatably retained in the outer member concentrically with the same and having a depression formed in an outer circumference thereof; at least one planet gear loosely and rotatably retained in the depression and engaging the inner teeth; and a removed portion formed in the outer circumference of the inner member adjacent the depression. When the inner member rotates in one direction with respect to the outer member, the planet gear freely rotates inside the depression. When the inner member rotates in an opposite direction with respect to the outer member, a part of teeth of the planet gear engages the removed portion. The planet gear is retained in the depression via a moving-range regulating member for regulating a moving range of the planet gear in radial and circumferential directions.
