  • Patent number: 11912133
    Abstract: A vehicle drive unit includes an internal combustion engine (21), an electromotive unit (23) having a first electric motor (31) and a second electric motor (33), an inverter (27) disposed above the electromotive unit, a first harness (41) that electrically connects the inverter and a first terminal block (61) of the first electric motor, and a second harness (42) that electrically connects the inverter and a second terminal block (62) of the second electric motor. The first electric motor and the second electric motor are disposed in a vehicle front-rear direction. Of the first electric motor and the second electric motor, one electric motor is disposed on the front side in the front-rear direction, and the other electric motor is disposed on the rear side in the front-rear direction. The other electric motor is offset upward in the up-down direction with respect to the one electric motor.
