<p><P>PROBLEM TO BE SOLVED: To provide a one-way clutch capable of preventing deformation of retainers by allowing rotation of the retainers in a lock direction at an angle corresponding to a displacement angle of each of the rollers in relation to a narrow side in a wedge space in loaded with torque. <P>SOLUTION: This one-way clutch is provided with an inner ring body 42, an outer ring body 41, cam surfaces 43 formed with a plurality of wedge-like spaces at prescribed intervals in a peripheral direction, the rollers 61, coil springs 60 and retainers 50. Each of flat surface 47 and engaging piece 55 as engaging portions receiving reaction force of the coil springs 60 by preventing rotation of the retainers 50 in a free direction is formed between the retainers 50 and members formed with the cam surfaces 43. A contact evasion portion 56 allowing rotation of the retainers 50 in the lock direction in the range of a prescribed angle is formed into a cut-out shape in the engaging piece 55. An allowable rotation angleθof each of the retainers 50 in the lock direction is set to an angle corresponding to the displacement angleαin relation to the narrow side in the wedge space of each of the rollers 61 in loaded with torque. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
