PROBLEM TO BE SOLVED: To enable lock on a vehicle to be released even when operation of a driving section becomes impossible in a parking lock device for electrically locking the vehicle.SOLUTION: A parking lock device includes: a first parking lock mechanism (15A) for locking rotation in one direction of first driving wheels (2) in a locking state and releasing the locking state by rotation in the reverse direction of the first driving wheels; a first driving section (15B) for switching the locking state of the first parking lock mechanism; a second parking lock mechanism (16A) provided in the middle of a power transmission path of second driving wheels, locking rotation in one direction of the second driving wheels (3) in a locking state and releasing the locking state by rotation in the reverse direction of the second driving wheels; and a second driving section (16B) for switching the locking state of the second parking lock mechanism. A rotating direction of the first driving wheels (2) to be locked is reverse to a rotating direction of the second driving wheels (3).SELECTED DRAWING: Figure 1 【課題】電動で車両をロックするパーキングロック装置において、その駆動部が動作不能となった場合でも、車両のロックを解除可能とする。【解決手段】ロック状態で、第１駆動輪（２）の一方向の回転をロックし、第１駆動輪の逆方向の回転によりロック状態が解除される第１パーキングロック機構（１５Ａ）と、第１パーキングロック機構のロック状態を切り替える第１駆動部（１５Ｂ）と、第２駆動輪の動力伝達経路の途中に設けられ、ロック状態で、第２駆動輪（３）の一方向の回転をロックし、且つ、第２駆動輪の逆方向の回転によりロック状態が解除される第２パーキングロック機構（１６Ａ）と、第２パーキングロック機構のロック状態を切り替える第２駆動部（１６Ｂ）と、を備えている。そして、ロックされる第１駆動輪（２）の回転方向と第２駆動輪（３）の回転方向とが逆方向である。【選択図】図１
