Abstract
A turning apparatus includes: an electric motor; a pinion gear that rotationally drives a wheel gear provided in a rotor in a first rotation direction and moves to a first position where the pinion gear can transmit a rotation of the electric motor to the wheel gear and a second position where the pinion gear cannot transmit the rotation of the electric motor to the wheel gear; a current value detection unit that detects a current value of the electric motor in a state where the pinion gear is positioned at the first position; and a control device that controls the electric motor to rotate the pinion gear in a second rotation direction opposite to the first rotation direction based on the current value detected by the current value detection unit.
