POWER SYSTEM

A power system includes: a rotating body; a housing accommodating the rotating body; and a storage portion provided at a bottom of the housing. A part of the rotating body is located in the storage portion. The housing includes: a supply target portion; and a direction changing portion. The direction changing portion includes: a collecting portion that is gradually inclined toward a downstream side in a rotation direction of the rotating body so as to be separated from an outer periphery of the rotating body and that receives the liquid medium scattered by the rotating body; and a guiding portion that is provided so as to cross a lower end of the collecting portion and that is gradually inclined downward toward the supply target portion. 本发明提供种抑制壳体的大型化并能够将借助旋转体而飞散的液状介质适当向配置在旋转体的轴向侧的供给对象部供给的动力装置，具备：第二齿轮；电动机，其配置在第二齿轮的轴向侧；壳体，其容纳第二齿轮及电动机；储存部，其设置于该壳体的底部并储存润滑油，第二齿轮的部分位于储存部，其中，在壳体的内表面设置有将借助第二齿轮而飞散的润滑油的流动方向朝向电动机转换的方向转换部。方向转换部具备：捕集部，其以在第二齿轮的旋转方向上随着朝向下游侧而远离第二齿轮的外周的方式倾斜；引导部，其交叉设置于捕集部的下端，并随着朝向电动机而向下方倾斜。
