To prevent the enlargement of a park lock device.SOLUTION: A park lock device comprises: a park gear 51 arranged at one of rotating shafts of a vehicle drive unit, and has a plurality of engagement recesses 51a at an external peripheral part; an engagement pin 52 engaged with the recess 51a of the park gear 51; and a park cam 54 for making the engagement pin 51 movable to a position engaged with the recess 51a of the park gear 51, and a standby position not engaged with the recess. The engagement pin 52 has an abutment part 52b abutting on the park cam 54, and moves to the park gear 51 in a radial direction depending on an abutment state of the park cam 54 and the abutment part 52b. The park cam 54 is a rotating cam abutting on the abutment part 52b of the engagement pin 52, and the engagement pin 52 is arranged on a line for connecting a rotation center of the park gear 54 and a rotation center of a rotating shaft 55 for rotating the park cam 54.SELECTED DRAWING: Figure 8
【課題】 この発明は、パークロック装置の大型化を防止する。【解決手段】 車両駆動装置のいずれか1つの回転軸に設けられ、外周部に係合のための凹部51aを複数設けたパークギヤ51と、パークギヤ51の凹部51aにパークギヤの凹部に係合する係合ピン52と、係合ピン51をパークギヤ51の凹部51aに係合する位置と係合しない待機位置とに移動可能にするパークカム54とを備え、係合ピン52は、パークカム54と当接する当接部52bを有し、パークカム54と当接部52bの当接状態によってパークギヤ51の半径方向に移動し、パークカム54は、係合ピン52の当接部52bと当接する回転カムであり、パークギヤ54の回転中心とパークカム54を回転させる回転軸55の回転中心とを結ぶ線上に、係合ピン52が設けられている。【選択図】 図8
