Kind Code:
B2
Abstract:
[Problem] In a one-way power transmission mechanism, to ensure a high allowable torque and make the mechanism thinner. [Solution] The present invention relates to a one-way power transmission device, which is configured so that when an input rotator (30) rotates, pressing force-transmitting parts (31) are brought into contact with engaging pieces (41, 42), after which the pressing force-transmitting parts come into contact with circumferential direction end faces in recesses (22) and press an output rotator (20). For the engaging pieces (41, 42), a first contact surface (P1) is formed as a convex surface with a curvature smaller than an imaginary circle that touches both the inner circumferential surface (11a) of a receiving chamber (11) and a cam surface (21, 23) and a curvature equal to or greater than the curvature of the inner circumferential surface (11a) of the receiving chamber (11).
