<p><P>PROBLEM TO BE SOLVED: To provide a one-way clutch which can easily shortens the arranging interval (arranging pitch) between neighboring rollers, and is improved in torque capacity by increasing the number of rollers or is reduced in size. <P>SOLUTION: A plurality of wedgelike shape spaces are formed between the opposed circumferential surfaces of an inner race body 11 and an outer race body 21. Rollers 40 of the same number as the plurality of the wedgelike spaces, and coil springs 45 for individually energizing the respective rollers 40 in the direction toward their narrow sides are arranged respectively in a plurality of the wedgelike spaces in the state where the rollers 40 and the coil springs are retained by a retainer 31. The coil springs 45 are wound so that the coil springs 45 are long in the axial direction of the rollers 40, and that the length of its major axis is longer than the length of the rollers. The retainer 31 has a pair of end plates 32 to be fixed to the outer circumferential surface of the inner race body 11 or the inner circumferential surface of the outer race body 21 so as to keep small clearances from both end surfaces of the rollers 40. A pair of end plates 32 have opening portions 34 formed such that both side portions of the coil springs 45 in the direction of its major axis are inserted thereinto. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
