To provide a parking lock device capable of miniaturizing the entire device.SOLUTION: A parking lock device comprises: a parking gear 71 rotating around a first rotary shaft; a parking pole 72 including a protrusion part to be engaged with the parking gear, and rotating around a second rotary shaft along the first rotary shaft; a parking rod 73 including a cam member 731; a flange 75 for supporting the parking rod; a manual shaft to be connected with the flange; an actuator for moving the parking rod by rotating the flange via the manual shaft; and a regulation member for regulating the rotation of the flange. The flange includes a rotary plate 751 rotating with the manual shaft being the shaft, and a support plate 752 connected to the rotary plate and rotating integrally with the rotary plate. The parking rod has an overlapping part which is overlapped with the rotary plate when viewed from the shaft direction of the manual shaft.SELECTED DRAWING: Figure 5 【課題】装置全体を小型化することができるパーキングロック装置を提供する。【解決手段】第１の回転軸を中心に回転するパーキングギヤ７１と、パーキングギヤと噛み合う突起部を有し、第１の回転軸に沿った第２の回転軸を中心に回転するパーキングポール７２と、カム部材７３１を有するパーキングロッド７３と、パーキングロッドを支持するフランジ７５と、フランジと連結されるマニュアルシャフトと、マニュアルシャフトを介してフランジを回転させることにより、パーキングロッドを移動させるアクチュエータと、フランジの回転を規制する規制部材とを備える。フランジは、マニュアルシャフトを軸として回転する回転プレート７５１と回転プレートと連結されて回転プレートと一体的に回転する支持プレート７５２とを有する。パーキングロッドは、マニュアルシャフトの軸方向から見て、回転プレートと重なる重畳部を有する。【選択図】図５
