A two-motor vehicle-driving apparatus is provided where the size of speed reducers in a radial direction is small. A motor shaft of the electric motor has an axial-through hollow structure. The motor shaft is provided with an input gear integrally therewith at its end closer to the speed reducer, with an output shaft provided inside the hollow motor shaft coaxially therewith. The output shaft has an output gear integrally therewith at its end closer to the speed reducer. The speed reducer is provided with one or more intermediate shafts rotatably in parallel with the motor shaft and the output shaft. The intermediate shaft is provided with a plurality of gears integrally therewith for engagement with the input gear of the motor shaft and with the output gear of the output shaft to transmit rotation of the motor shaft to the output shaft at a reduced speed.
