Zusammenfassung:	A parking lock apparatus includes a parking gear rotatable together with a rotating body of a transmission. A slider is to be switched between a parking lock position in which a parking pawl is in engagement with the parking gear and a parking release position in which the parking pawl is out of engagement with the parking gear. A hydraulic circuit includes a third oil passage through which a first line pressure is applied to push the slider toward the parking release position, a fourth oil passage through which a second line pressure is applied to push the slider toward the parking lock direction, and a hydraulic cut valve provided in the third oil passage to be opened when a difference between the first line pressure and the second line pressure is higher than or equal to a threshold pressure when applying line
