To provide a movable body driving unit which lubricates a gear device in a gear housing part with oil for oil cooling of an electric motor while inhibiting an increase in size and the number of components.SOLUTION: A movable body driving unit 20 includes: a case 21; an electric motor which is disposed at a motor housing part Sa formed at one side as viewed in a predetermined first direction of the inner side of the case and has a motor shaft extending in the first direction; a gear device which is disposed in a gear housing part formed at the other side as viewed in the first direction at the inner side of the case and serving as an oil sump; a power transmission mechanism which is disposed at the inner side of the case and transmits power between the motor shaft and the gear device; an oil passage 130 allowing mutual communication between the motor housing part and the gear housing part at the inner side of the case; and an oil introduction port, an oil discharge port, and an external oil passage. The external oil passage is connected to the oil introduction port and the oil discharge port at the outer side of the case and has an oil pump.SELECTED DRAWING: Figure 7A

    【課題】移動体駆動ユニットにおいて、大型化及び部品点数の増大を抑制しながら、電動モータの油冷却用の油でギア収容部内のギア装置を潤滑することである。【解決手段】移動体駆動ユニット20は、ケース21と、ケースの内側の所定の第1方向一方側に形成されたモータ収容部Saに配置される電動モータであって、第1方向に延びるモータ軸を有する電動モータと、ケースの内側の第1方向他方側に形成され油溜めを兼ねるギア収容部に配置されるギア装置と、ケースの内側に配置されモータ軸とギア装置との間で動力を伝達する動力伝達機構と、ケースの内側でモータ収容部とギア収容部とを相互連通する油通路130と、油導入ポート、油排出ポート及び外部油路とを含む。外部油路は、ケースの外側で油導入ポートと油排出ポートとに接続され、油ポンプを有する。【選択図】図7A
