An oil passage (50) has at least one oil hole (59a) that is disposed in a higher position than an input shaft (32) within a space (20) farther outward in a vehicle width direction than a dividing wall(39b) of a casing (10), the at least one oil hole (59a) allowing lubricating oil to flow out downward. A guide member (95) receives the lubricating oil flowing out from the oil hole (59a) and guidesthe lubricating oil to an outer peripheral surface of a bearing-holding part (81). A leading hole (92) penetrates through the bearing-holding part (81) from the outer peripheral surface to an inner peripheral surface of the bearing-holding part (81), and leads lubricating oil guided by the guide member (95) to a motor-side bearing (27).
油通路(50)在比壳体(10)的隔壁(39b)靠车宽方向外侧的空间(20)内具有配置在比输入轴(32)靠上方的位置且使润滑油向下方流出的至少一个油孔(59a)。引导构件(95)接受从油孔(59a)流出的润滑油,向轴承保持部(81)的外周面引导。引导孔(92)从轴承保持部(81)的外周面朝向内周面地贯通轴承保持部(81),将由引导构件(95)引导来的润滑油向电动机侧轴承(27)引导。
