| Zusammenfassung: | The invention provides a drive device which is provided with a motor having a rotor capable of rotating about a motor shaft extending in a direction intersecting a vertical direction, and a stator positioned on the outside in the radial direction of the rotor; and a first refrigerant injection part and a second refrigerant injection part which are disposed on the outside in the radial direction of the stator so as to be spaced apart from each other in the circumferential direction, and which inject a refrigerant toward the stator. At least one of the first refrigerant injection part and the second refrigerant injection part is provided with an inner injection opening, and the inner injection opening is inclined to the side where the other refrigerant injection part is located relative to the direction facing the motor shaft in the circumferential direction. Each of the first refrigerant injection part and the second refrigerant injection part has an outer injection opening that is inclined in the circumferent |
