To provide a vehicle parking lock device including a parking gear which can release torque remaining in a rotary member when the vehicle parking lock device is turned into a lock state in a state that the torque remains in the rotary member.SOLUTION: A parking gear 82 includes: a parking lock gear 92 which includes outer peripheral teeth 90 which engage with a lock pawl 84 and rotates around a rotation axis C1; and a parking lock gear base 94 which is fixed to an output shaft 32 so as to be rotatable around the rotation axis C1 relative to the packing lock gear 92. A space S which expands or shrinks in a circumferential direction in conjunction with relative rotation of the packing lock gear 92 and the parking lock gear base 94 is formed between the parking lock gear 92 and the parking lock gear base 94. A spring 108 is provided in a preload state in the space S.SELECTED DRAWING: Figure 2

    【課題】回転部材にトルクが残った状態で車両用パーキングロック装置がロック状態となった場合に、回転部材に残ったトルクを逃がすことができるパーキングギヤを備えた車両用パーキングロック装置を提供する。【解決手段】パーキングギヤ82は、ロック爪84と噛み合う外周歯90を備え回転軸線C1まわりに回転するパーキングロックギヤ92と、パーキングロックギヤ92に対して回転軸線C1まわりに相対回転可能に出力軸32に固定されたパーキングロックギヤベース94と、を含み、パーキングロックギヤ92とパーキングロックギヤベース94との間には、パーキングロックギヤ92およびパーキングロックギヤベース94の相対回転に伴って周方向に伸縮する空間Sが形成され、空間S内には、スプリング108が予圧状態で設けられている。【選択図】図2
