PROBLEM TO BE SOLVED: To reduce rising of oil by devising the shape of a delivery pipe.SOLUTION: A second delivery pipe (17) extends in a radial direction so as to pass through a trunk (12) of a casing (11), and an inlet side end of the second delivery pipe (17) is bent toward the upper side, thereby allowing the inlet side of the second delivery pipe (17) to be opened upward. The inlet side end of the second delivery pipe (17) is also opened upward at a position overlapping with an axis as viewed from the axial direction of a drive shaft (23), and is located in the vicinity of the central axis of the trunk (12). 【課題】吐出管の形状を工夫することで、油上がりを低減できるようにする。【解決手段】第２吐出管（17）は、ケーシング（11）の胴部（12）を貫通するように径方向に延びるとともに、入口側の端部が上側に折り曲げられることで、第２吐出管（17）の入口側が上向きに開口している。また、第２吐出管（17）の入口側の端部は、駆動軸（23）の軸方向から見て軸心に重なり合う位置で上方向に開口しており、胴部（12）の中心軸付近に位置している。【選択図】図２
