Claim 17:
18. A vehicle drive apparatus comprising:
a rotating electrical machine provided with a rotor and a stator;
an input member drivingly coupled to the rotor;
a counter gear mechanism;
a differential gear mechanism that distributes, to a first wheel and a second wheel, a driving force transmitted thereto from the rotating electrical machine via the input member and the counter gear mechanism;
a case that houses the rotating electrical machine, the input member, the counter gear mechanism, and the differential gear mechanism; and
a pump portion that suctions a coolant and discharges the coolant into the case, wherein
the rotating electrical machine and the input member are placed on a first axis,
the counter gear mechanism is placed on a second axis different from the first axis,
the differential gear mechanism is placed on a third axis different from the first axis and the second axis,
the input member, the counter gear mechanism, and the differential gear mechanism have portions that are placed on an axial first side with respect to the rotating electrical machine, the axial first side being one side in an axial direction,
a side opposite the axial first side in the axial direction is defined as an axial second side,
the differential gear mechanism is coupled to the first wheel via a shaft member on the third axis, the shaft member having a portion placed on the axial second side with respect to the differential gear mechanism,
the pump portion is placed on an opposite side of an imaginary plane from the second axis and at a location that overlaps at least one of the rotating electrical machine and the differential gear mechanism in an axial view that is along the axial direction, the imaginary plane passing through the first axis and the third axis,
the pump portion is placed on the axial first side with respect to the rotating electrical machine, and
the coolant discharged by the pump portion is supplied to the rotating electrical machine.
