Vehicle drive apparatus

1. A vehicle drive apparatus comprising:

an internal combustion engine;

a first rotary electrical machine configured to be driven to generate electrical power by the internal combustion engine;

a second rotary electrical machine configured to drive a vehicle driveshaft to rotate via a reducer;

a first gear secured to an output shaft of the internal combustion engine;

a first gear train configured to transfer rotation of the first gear to the first rotary electrical machine;

a countershaft arranged parallel to the output shaft;

a second gear rotatably supported on the countershaft and meshed with the first gear;

a third gear rotatably supported on the output shaft;

a fourth gear secured to the countershaft and meshed with the third gear;

a second gear train configured to transfer rotation of the fourth gear to the vehicle driveshaft;

a first clutch configured to engage the second gear with the countershaft;

a second clutch configured to engage the third gear with the output shaft; and

a third clutch configured to connect and disconnect propagation of a motive power between the second rotary electrical machine and the reducer,

the first gear train and the second gear being arranged on a first plane that extends in a direction orthogonal to an axial direction of the output shaft,

the third gear, the fourth gear, and the second gear train being arranged on a second plane that is set apart by a prescribed axial-direction distance from the first plane and that is parallel to the first plane, and

the first clutch and the second clutch being arranged on a third plane that is parallel to the first plane and that is positioned between the first plane and the second plane.

2. The vehicle drive apparatus according to claim 1 , wherein

the fourth gear is a reduction small gear that meshes with a reduction large gear in the second gear train.
