PROBLEM TO BE SOLVED: To provide a lubrication structure of a motor drive unit for a vehicle which can stably and continuously perform lubrication even if an inertia force in a horizontal direction acts on a lubricant at turning traveling.SOLUTION: A structure of a motor drive unit (21) for a vehicle comprises: a motor part (A) and a reduction part (B) which adjoin each other in a horizontal direction; a lubricant circuit which supplies lubricants to the motor part and the reduction part; and a bulkhead (22p). The lubrication circuit has an oil tank (53) which is arranged at a lower side of the motor part and the reduction part, supply parts (51 to 57) which suck the lubricants from the oil tank, and supplies the lubricants to the motor part and the reduction part, collection oil passages (65, 66) which extend to the oil tank from the motor part and the reduction part, and collects the lubricants from the motor part and the reduction part, and an on-off valve (71) which is arranged at least at either of the collection oil passage at the motor part side and the collection oil passage at the reduction part side, and closed by receiving an inertia force in the horizontal direction.SELECTED DRAWING: Figure 1

    【課題】旋回走行時等、水平方向の慣性力が潤滑油に作用しても安定して継続的に潤滑することができる車両用モータ駆動装置の潤滑構造を提供する。【解決手段】車両用モータ駆動装置(21)は互いに水平方向に隣接するモータ部(A)および減速部(B)と、モータ部および減速部に潤滑油を供給する潤滑油回路と、障壁(22p)を備える。潤滑油回路はモータ部および減速部の下側に設けられるオイルタンク(53)と、オイルタンクから潤滑油を吸入してモータ部および減速部に潤滑油を供給する供給部(51〜57)と、モータ部および減速部からオイルタンクまでそれぞれ延びモータ部および減速部から潤滑油をそれぞれ回収する回収油路(65,66)と、モータ部側の回収油路および減速部側の回収油路の少なくとも一方に設けられ水平方向の慣性力を受けて閉じる開閉弁(71)を有する。【選択図】図1
