Abstract

A shift device includes: a shift switching member including valley parts corresponding to a shift position; a positioning member provided to establish the shift position in a state of being fitted into any one of the valley parts; a motor including a rotor and a stator and driving the shift switching member; a speed reduction mechanism section rotating the shift switching member in a state in which a rotation speed transmitted from the motor is reduced; a rotor rotational angle sensor detecting a rotational angle of the rotor; and an output shaft rotational angle sensor detecting a rotational angle of the shift switching member A width of a backlash included in the speed reduction mechanism section is detected, and the rotational angle of the motor corresponding to the center of the backlash is acquired.
