Abstract
A shift device mounted on a vehicle includes a motor configured to drive, by electric power supplied from a power supply mounted on the vehicle, a shift switching member configured to switch shift positions, a cut-off unit configured to cut off conduction of a power supply line through which the electric power is supplied to the motor, and a drive circuit unit configured to output the electric power to the motor and including a driving switching element configured to execute a switching operation. The shift device is configured to determine an abnormality of the power supply line when a voltage of the power supply line is smaller than a predetermined threshold value, turn off the driving switching element, and cut off the conduction of the power supply line by the cut-off unit.
