1. A vehicular drive device comprising:
an input member drivingly coupled to an internal combustion engine through a damper; a first rotary electric machine; a second rotary electric machine; a differential gear device including three rotational elements; an output device drivingly coupled to a wheel, in which, among the three rotational elements of the differential gear device, one rotational element is drivingly coupled to the input member, another rotational element is drivingly coupled to the first rotary electric machine, an output element as a resting rotational element is drivingly coupled to the output device, and the second rotary electric machine is drivingly coupled to the output device; a first gear mechanism that transmits a driving force between the output element and the output device; and a second gear mechanism that transmits a driving force between the second rotary electric machine and the output device, wherein
the damper, the differential gear device, and the first rotary electric machine are disposed side by side on a first axis that is common thereto,the second rotary electric machine is disposed on a second axis that is parallel to the first axis and is different from the first axis,the output device is disposed on a third axis that is parallel to the first axis and is different from the first axis and the second axis,the first gear mechanism is disposed on a fourth axis that is positioned on a side opposite to the second axis side with respect to a first reference plane that is a plane including both the first axis and the third axis, andthe second gear mechanism is disposed on a fifth axis that is positioned on a side opposite to the first axis side with respect to a second reference plane that is a plane including both the second axis and the third axis. |
