Abstract

A torque transmission mechanism includes a first member having a cylindrical shape and configured to be rotatable around a rotation axis, the first member including an outer peripheral surface provided with a first groove having a zigzag shape extending around the rotation axis, a second member having an annular shape surrounding the first member and configured to be rotatable around the rotation axis, the second member including an inner peripheral surface provided with a second groove having a zigzag shape extending around the rotation axis, one or more first rolling members disposed in and configured to be rollable in the first groove and in the second groove, and a first regulating member disposed between the first member and the second member and configured to allow movement of the first rolling members along the rotation axis and regulate movement of the first rolling members around the rotation axis.
