Beschreibung
Zusammenfassung:	A motor has a rotor and a stator surrounding the rotor; a transmission mechanism having gears; a housing having a motor accommodating portion accommodating the motor, and a gear accommodating portion accommodating the transmission mechanism; a fluid stored in the housing; and a flow path through which the fluid flows. The housing has a side wall portion that defines an internal space of the motor accommodating portion and an internal space of the gear accommodating portion. The flow path includes an intra-housing flow path disposed in an internal space of the motor accommodating portion and provided with a feed hole for ejecting a fluid. A bearing holder that supports the shaft of the transmission mechanism via a bearing is provided on a gear facing surface of the side wall portion facing the transmission mechanism. The feed hole faces the bearing via an opening provided in the side wall portion.
