Abstract
An apparatus for transmitting power from a motor to a movable member comprises a drum connected to the movable member, a cam member rotated around a center shaft by the motor, a clutch member displaced from a standby position to a full engagement position through an initial engagement position when the cam member is rotated, a return spring for urging the clutch member from the full engagement position toward the standby position, and a brake member for applying a predetermined frictional resistance to the clutch member. The clutch member moves the brake member from a braking position to a non-braking position when the clutch member is moved from the initial engagement position toward the full engagement position. The cam member has a cam face which moves the clutch member from the standby position to the full engagement position and a holding face which disables the clutch member from returning from the full engagement position to the standby position.
