To provide a park lock device of a vehicle driving device capable of preventing enlargement of members constituting a park lock, and to surely release engagement of a park gear and a park pole even in parking on a slope of large gradient.SOLUTION: A park lock device of a vehicle driving device includes a park gear 51 disposed on a rotating shaft 31 of the vehicle driving device and having a plurality of recessed portions 51a for engagement, on an outer peripheral portion, a park pole 52 having projections 52a engaged with the recessed portions 51a of the park gear 51, and oscillatable between an engagement position and a non-engagement position through a supporting shaft, and first and second park cams 54a, 54b oscillatable between a position to engage the projections 52a of the park pole 52 with the recessed portions 51a of the park gear 51, and a standby position not to engage. The first and second park cams 54a, 54b are rotary eccentric cams, the first park cam 54a is kept into contact with a side opposite to a park gear 51 side of the park pole 52, and the second park cam 54b is kept into contact with a park gear 51 side of the park pole 52.SELECTED DRAWING: Figure 6

    【課題】 パークロックを構成する部材の大型化を防止すると共に、勾配の大きな坂路で駐車した場合でも、パークギヤとパークポールの係合を確実に解除できる車両駆動装置のパークロック装置を提供する。【解決手段】 車両駆動装置の回転軸31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に係合する突起52aを有し、係合する位置と係合しない位置とに支持軸を介して揺動可能なパークポール52と、パークポール52の突起52a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揺動可能にする第1、第2のパークカム54a、54bと、を備え、第1、第2のパークカム54a、54bは、回転式の偏芯カムであり、第1のパークカム54aは、パークポール52のパークギヤ51側とは反対側で当接し、第2のパークカム54bは、パークポール52のパークギヤ51側に当接する。【選択図】 図6
