Abstract
A shift device includes: a shift switching member including valley portions provided so as to correspond to shift positions; a positioning member causing the shift position to be established while being fitted in any of the valley portions of the shift switching member; a motor driving the shift switching member and including a rotor and a stator; a driving force transmission mechanism transmitting a driving force from the motor to the shift switching member; and a rotor rotation angle sensor and an output shaft rotation angle sensor detecting rotation angles of the rotor and the shift switching member. The shift device corrects a deviation from a center of a preset backlash when a backlash width included in the driving force transmission mechanism detected based on output values of the output shaft rotation angle sensor and the rotor rotation angle sensor is a value or more during a shift switching operation.
