Vehicle drive device

A vehicle drive device comprising

• a rotary electric machine,
• a power transfer mechanism that transfers a rotational drive force between the rotary electric machine and a plurality of wheels,
• a case that houses at least a part of the power transfer mechanism and the rotary electric machine, and
• a hydraulic pump, wherein:
• the power transfer mechanism includes a differential gear mechanism that distributes torque input from a rotary electric machine side to the plurality of wheels,
• the case is provided with a first reservoir that stores oil suctioned by the hydraulic pump inside the case, and a second reservoir that stores oil inside the case;
• the hydraulic pump is a pump driven always in conjunction with rotation of the differential gear mechanism;
• a delivery port of the hydraulic pump communicates with a supply through which oil is supplied to the second reservoir;
• at least a part of the differential gear mechanism is housed in the first reservoir;
• and
• a first height is a height of an oil surface in the first reservoir in a state in which rotation of the plurality of wheels is stopped, and the first height is such a height that at least a part of the differential gear mechanism is immersed in oil stored in the first reservoir.

• at least a part of the differential gear mechanism is disposed at a height between an uppermost part and a lowermost part of a rotor of the rotary electric machine;
• a delivery port of the hydraulic pump communicates with a supply through which oil is supplied to the second reservoir;
• at least a part of the rotary electric machine is housed in the first reservoir;
• and
• a first height is a height of an oil surface in the first reservoir in a state in which rotation of the plurality of wheels is stopped, and the first height is such a height that at least a part of a rotor core of the rotor is immersed in oil stored in the first reservoir;
• and
• a second height is a height of an oil surface in the first reservoir in a state in which the plurality of wheels are rotating, and the second height is a height below a lowermost part of the rotor core.
