摘要

A one-way rotational transfer mechanism includes a rotary input member; a holding member including an axially orthogonal surface to the axis; a hollow-cylindrical rotary output shaft positioned coaxially around the rotary input member to be rotatable relative to the rotary input member, and including a cylindrical inner peripheral surface; a circumferential guide groove formed on the rotary input member; and a torque transfer ball installed between the axially orthogonal surface, the cylindrical inner peripheral surface and the circumferential guide groove, to roll on and be held between the axially orthogonal surface and the circumferential guide groove. The circumferential guide groove is shaped to make the torque transfer ball revolve around the rotary input member in a same direction as the rotary input member while trailing therebehind and to make the torque transfer ball press against the cylindrical inner peripheral surface when the rotary input member rotates.
