The present invention is provided with a motor and a housing. The motor has a rotor and a stator. The housing is in a cylindrical form and has a first housing, a second housing, and a partition wall. The first housing houses the motor. The second housing is disposed adjacent to a motor chamber and stores a cooling medium for cooling the motor. The partition wall partitions the first housing and the second housing, and is formed so as to be protruded from the inner circumferential surface to the radially inner side. The partition wall has provided therein a through-hole that causes the inside of the first housing and the inside of the second housing to be connected with each other. The housing has a bypass flow path. The bypass flow path is disposed outside the first housing and the second housing, and causes connection between an inlet port opened so as to face the inside of the first housing and an outlet port opened so as to face the inside of the second housing.
