Patent ID: 7214161

Claim:
A one-way clutch comprising: an outer member with inner teeth, an inner member rotatably disposed in the outer member and having at least one depression formed in an outer periphery thereof, and a removed portion formed in the outer periphery adjacent the depression, at least one planet gear rotatably retained in the depression to engage the inner teeth, moving-range regulating means for receiving the planet gear retained in the depression, said moving-range regulating means limiting the planet gear to move within a limited range in radial and circumferential directions so that when the inner member rotates in one direction relative to the outer member, the planet gear freely rotates inside the depression, and when the inner member rotates in an opposite direction relative to the outer member, the planet gear engages an edge of the removed portion not to freely rotate in the depression, and a holding member for supporting the planet gear together with the inner member, said planet gear having an axial portion, at least one of said holding member and said inner member having an elongated hole for receiving the axial portion so that the planet gear moves within the limited range.
