Abstract
An electric steering lock apparatus includes a cam plate rotated in an unlocking direction and a locking direction by driving a motor unit, and a lock shaft shifting between a lock position at which the rotation of the steering shaft is prevented and an unlock position at which the rotation of the steering shaft is permitted, following to the sliding surface of the cam plate, wherein, at the position of the cam plate at which the lock shaft is located at the unlock position, the center of rotation of the cam plate is set at an eccentric position with respect to the position of the center of gravity of the cam plate so that the rotation torque resulting from the own weight of the cam plate acts in the unlocking direction.
