Abstract
A one-way clutch includes an outer race, wherein a plurality of windows are formed in one plate-like member, is placed so as to be relatively rotatable with respect to an inner race wherein two plate-like members overlay each other and a ball raceway surface is formed by curved portions formed in outer peripheries of the plate-like members. Balls are accommodated in the windows. The face of each of the windows on the side of the outer periphery of the outer race is formed as a cam surface wherein the distance with respect to the ball raceway surface is reduced in a circumferential direction. Urging means for urging the balls in the direction is disposed. The maximum width of the one-way clutch is equal to the ball diameter and the thicknesses of the two plate-like members constituting the inner race, so that a one-way clutch of a reduced width is obtained.
