Abstract: A shift device includes: a motor drive circuit; a motor driver unit for driving the motor drive circuit; a control unit that controls the motor driver unit; a motor power supply path; a system power supply path; and a buck-boost unit that converts electric power supplied from the system power supply path to a predetermined voltage and outputs the voltage. Electric power is supplied to the control unit via the buck-boost unit, and either the electric power from the motor power supply path or the electric power from the system power supply path is supplied to the motor driver unit based on a voltage.
