Abstract
A range switching apparatus of a shift-by-wire system has: a main motor; a deceleration mechanism that amplifies torque generated by the main motor; an output shaft that outputs the torque amplified by the deceleration mechanism; an auxiliary motor; and an emergency drive mechanism. The emergency drive mechanism is disposed on the auxiliary motor shaft of the auxiliary motor, and that is connected to or disconnected from the deceleration mechanism by driving of the auxiliary motor. The emergency drive mechanism transfers output of the auxiliary motor to the deceleration mechanism, and rotates the output shaft by being connected to the deceleration mechanism.
