Abstract:
A roller type one-way clutch includes an outer race in which at least one pocket having a cam surface on an inner periphery thereof is formed, an inner race which is spaced away from the outer race on an inside diameter side in a radial direction and which is relatively rotatably disposed concentrically with respect to the outer race, a roller which is disposed in the pocket and which engages with the cam surface to transmit a torque between the outer race and the inner race, a spring which is disposed between the outer race and the roller in the pocket and which urges the roller in a direction in which the roller engages with the cam surface, and a side plate secured to be in contact with one end surface in an axial direction of the outer race. The side plate has a non-circular shape, the one end surface in the axial direction is annular, and at least a portion of the one end surface in the axial direction of the outer race is exposed in a state in which the side plate is secured.
