In an electronic parking lock apparatus, a relative rotation angle of an electric motor of an actuator is detected by a relative rotation angle sensor, an absolute rotation angle of the electric motor is calculated according to the relative rotation angle and reference rotation position information obtained by a rotation end limiting portion that limits a rotation end of a rotating component. An absolute rotation angle of the rotating component is detected by using an absolute rotation angle sensor, and the working status of the parking lock is determined according to the absolute rotation angle. The rotation end limiting portion used for obtaining the reference rotation position information of the relative rotation angle sensor and a detected component used for enabling the absolute rotation angle sensor to work to obtain the absolute rotation angle are provided in the same rotating component.
