1. A shift device comprising:
a shift switching member including a plurality of valley portions corresponding to shift positions;
a motor including a rotor and a stator and configured to drive the shift switching member;
a first drive system including a first inverter configured to output a voltage for driving the motor;
a second drive system provided separately from the first drive system and including a second inverter configured to output a voltage for driving the motor; and
a positioning member configured to be fitted into any one of the plurality of valley portions of the shift switching member to establish the corresponding shift position, wherein
when driving the motor, the shift position is switched by the voltages output from the first drive system and the second drive system,
the first drive system and the second drive system are connected to different power supplies, and
when a failure is detected in one of the first drive system and the second drive system during the shift switching, the drive of the motor by the one of the first drive system and the second drive system with the failure is stopped while the drive of the motor by the other of the first drive system and the second drive system is continued.
