MOTOR DRIVING FORCE TRANSMISSION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a motor driving force transmission apparatus which can smoothly carry out shifting operation from a cam mechanism to a clutch.SOLUTION: In a motor driving force transmission apparatus 1, a cam mechanism 7 includes an input cam member 70 that rotates upon reception of motor torque from a cam actuating electric motor 29 and an output cam member 71 that outputs cam thrust force P through movement due to rotation of the input cam member 70, and rotation of the output cam member 71 around the axial line O of a housing 2 is restricted by a restricting member 9 fixed to the housing 2.
