A motor and a housing are included. The motor has a rotor and a stator. The housing is cylindrical and has a first housing, a second housing, and a partition wall. The first housing accommodates the motor. The second housing is disposed adjacent to the motor chamber and stores a cooling medium for cooling the motor. The partition wall is formed to space the first housing from the second housing and protrudes radially inward from the inner circumferential surface. The partition wall is provided with a through hole that connects the interior of the first housing and the interior of the second housing. The housing has a bypass flow path. The bypass flow path is disposed outside the first housing and the second housing, and connects an inlet opening that opens to the inside of the first housing and an outlet opening that opens to the inside of the second housing.

    包括马达和外壳。马达具有转子及定子。外壳是筒状的,具有第一外壳、第二外壳以及分隔壁。第一外壳对马达进行收纳。第二外壳与马达室相邻地配置,积存对马达进行冷却的冷却介质。分隔壁形成为将第一外壳与第二外壳间隔开且从内周面向径向内侧突出。分隔壁设置有使第一外壳的内部与第二外壳的内部连通的贯穿孔。外壳具有旁通流路。旁通流路配置于第一外壳和第二外壳的外部,使朝第一外壳的内部开口的流入口与朝第二外壳的内部开口的流出口连通。
