Claims

[Claims for Utility Model Registration] (1) A sprag having a substantially oval cross-section and an arcuate concave surface continuous in the axial direction on at least one surface facing the column portion of the cage; A plurality of pillar parts are made to protrude in the axial direction from the side plate part to form a plurality of sprag holding windows, and one surface of the pillar part forming the holding window is provided with a base facing into the arcuate concave surface of the sprag. a cage body formed with an axial protrusion that makes line contact; an annular side plate that is connected to the axial end surface of the column portion; A sprag clutch includes a spring member that biases the sprag clutch. (2) Increase the circumferential dimension of the sprag on the inner and outer diameter sides of the axial protrusion position relative to the minimum circumferential dimension of the holding window defined by the axial protrusion of the column portion. A sprag clutch according to claim (1) of the utility model registration.゛(3) Utility model registration claim (1) in which the other surface of the sprag opposite to the pillar portion is swollen in an arc shape so as not to impede the swinging of the sprag around the axially protruding strip. Or the sprag clutch described in (2). (4) Forming axially uneven stripes on the outer diameter side ends of both surfaces forming the holding window of the column portion, and securing a plate spring that embraces the uneven stripes, The sprag clutch according to any one of claims (1) to (3), wherein a spring portion is formed to bias the sprag. (5) Any of the claims (1) to (4) for registering a utility model in which the axial protrusions on the cage column portion are formed of an arcuate surface with a radius of curvature smaller than the radius of curvature of the arcuate concave surface of the sprag. The sprag clutch mentioned in one of the above.
