Abstract

A transmission device has a clutch spring (8). The clutch spring (8) can generate rotational resistance that occurs when a pressure member (5) rotates relative to a clutch member (4) due to clearance between cam surfaces of a press-contact assisting cam or a back torque limiting cam. Thus, one end (8a) of the clutch spring (8) slides on a surface (10a) of a restricting member 10. A side surface (8b) of the clutch spring (8) is held in the longitudinal direction.
