To provide a parking lock device capable of reducing breakage of components caused by an impulse generated by the collision between a parking pole and a parking gear.SOLUTION: A parking lock device comprises: a parking gear 71 rotating around a first rotary shaft J4; a parking pole 72 including a protrusion part 72a to be engaged with the parking gear, and rotating around a second rotary shaft J6; a parking rod 73 including a cam member 731 and a rod body 732; a sleeve member 74 which includes a through-hole 74a penetrating in the direction along the second rotary shaft, and in which one end part of the rod body is inserted in the through-hole; and an actuator for moving the parking rod in the direction traversing the through-hole by rotationally driving a flange 75. The parking pole rotates between a first position in which the protrusion part is engaged with the parking gear and a second position in which the protrusion part is separated from the parking gear. The through-hole is a long hole when viewed from the direction along the second rotary shaft.SELECTED DRAWING: Figure 3 【課題】パーキングポールとパーキングギヤとの衝突によって発生する衝撃に起因する構成部品の破損を低減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Ｊ４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７２ａを有し、第２の回転軸Ｊ６を中心に回転するパーキングポール７２と、カム部材７３１と、ロッド本体７３２とを有するパーキングロッド７３と、第２の回転軸に沿った方向に貫通する貫通孔７４ａを有し、貫通孔にロッド本体の一端部が挿入されるスリーブ部材７４と、フランジ７５を回転駆動することにより、貫通孔を横切る方向にパーキングロッドを移動させるアクチュエータと、を備える。パーキングポールは、突起部がパーキングギヤと噛み合う第１の位置と、突起部がパーキングギヤから離間する第２の位置との間で回転する。貫通孔は第２の回転軸に沿った方向から見て長孔である。【選択図】図３
