<p><P>PROBLEM TO BE SOLVED: To provide an easily assemblable one-way clutch. <P>SOLUTION: An inner ring 12 is incorporated into the inside of an outer ring 11 having a cylindrical inner face 13. A plurality of cam faces 17 are provided to the outer periphery of the inner ring 12. An engaging face 19 engaged with the cam face 17 is provided to the inner periphery of a retainer 18 fitted outside of the inner ring 12 from one side of the inner ring 12. A pocket 21 is formed to the retainer 18 oppositely to each cam face 17. An engaging piece 22 and an elastic member 23, which energizes the engaging piece 22 in its direction of being engaged with the cylindrical inner face 13 and the cam face 17, are incorporated into each pocket 21. The assemblability of the one-way clutch is improved by forming taper-shaped fitting guide faces 24, 25 to the inner peripheral part on the insertion-side end face of the retainer 18 and the outer peripheral part on the retainer reception-side end face of the inner ring 12 so as to make the retainer 18 smoothly fittable to the inner ring 12. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
