PROBLEM TO BE SOLVED: To solve the problem that, when a driving side is reversely rotated, a planetary gear idly rotates in a recessed part provided in an inner member to cause noise, and when the driving side rotates at a high speed, the speed of the idle rotation of the planetary gear in the recessed part becomes high in speed, so that high pitch noise occurs and jagged noise occurs. SOLUTION: This one-way clutch 1 includes a sun gear 3 having teeth formed on the outer periphery thereof, a plurality of planetary gears 4 meshed with the sun gear 3 by the teeth formed on the outer periphery thereof, a plurality of storage parts 24 for freely rotatably storing the planetary gears 4, and an outer member 2 relatively rotating coaxially on the same plane of rotation with a shaft J1 of the sun gear 3. A projection 23 abutting on the planetary gear 4 is provided in one of rotating directions R1 and R2 of the storage part 24. COPYRIGHT: (C)2010,JPO&INPIT
