A parking lock device includes a parking mechanism, a lock state switching member, a lock-released state keeper, a selector, a vehicle speed detector, a switching controller, and a keeping controller. The switching controller is configured to, when a parking range is selected, stop supplying hydraulic pressure to the lock state switching member, and when a shift range other than the parking range is selected, supply the hydraulic pressure. The keeping controller is configured to, when a shift range other than the parking range is selected and a vehicle speed is equal to or higher than a predetermined speed, supply power to the lock-released state keeper to keep lock of a parking gear released, and when a shift range other than the parking range is selected and when the vehicle speed is lower than the predetermined speed, stop supplying the power to the lock-released state keeper.
