PROBLEM TO BE SOLVED: To smoothen suction of a lubrication oil under a low temperature environment.SOLUTION: A vehicle motor drive device includes: a lubrication oil tank (53) which stores a lubrication oil; and an oil pump (51) for suctioning the lubrication oil from a suction port (53a) of the lubrication oil tank and circulating the lubrication oil. The vehicle motor drive device circulates the lubrication oil in an internal circulation method. A heat transmission member (30), which extends crossing a border part between a space (L) in the motor part and a space in the lubrication oil tank (53), is provided in the vehicle motor drive device having the above structure. The heat transfer member (30) collects heat of a heating part (13) of the motor part and guides the collected heat to an area near the suction port (53a) of the lubrication oil tank (53).SELECTED DRAWING: Figure 4

    【課題】低温度環境下においても潤滑油の吸込みを円滑化すること。【解決手段】車両用モータ駆動装置は、潤滑油を貯留する潤滑油タンク(53)と、潤滑油タンクの吸込み口(53a)から潤滑油を吸い込んで、潤滑油を循環させるためのオイルポンプ(51)とを備えており、内部循環方式によって潤滑油を循環させる。このような構成の車両用モータ駆動装置に、モータ部内の空間(L)と潤滑油タンク(53)内の空間との境界部を跨って延びる伝熱部材(30)を設ける。伝熱部材(30)は、モータ部の発熱部分(13)の熱を採取し、採取した熱を潤滑油タンク(53)の吸込み口(53a)付近に導く。【選択図】図4
