Claims

[Claims for Utility Model Registration] (1) An outer ring body is rotatably arranged around the outer periphery of the inner ring body, and one of the facing surfaces of the two wheels has a groove that is aligned with the axis of the inner ring body. The ring body has a gear-shaped uneven surface parallel to the radial direction of the inner ring body, and the other surface is opposite to the one surface. The locking piece retaining groove has a parallel wall surface and is open on the other surface, and the groove has different lengths protruding from the opening of the groove, and each of the distal ends A locking piece is provided inside the locking piece so that the different locking ends abut against each slope of one of the uneven surfaces at different times, and the locking piece has the respective different locking ends at the rear end thereof. A one-way clutch characterized in that a spring portion is provided to bias the clutch in the direction of the uneven surface. (2) The one-way clutch according to claim 1, which is incorporated as an intermediate member of a rotational force transmission mechanism. (3) The one-way clutch according to claim 1, wherein either the inner ring body or the outer ring body is a rotational force transmission side or a rotational force receiving side of the rotational force transmission mechanism. (4) The one-way clutch according to claim 1, wherein the outer ring body is a paper feed roller for a copying machine, a facsimile machine, a printer, or the like.
