Claim 2:
3. The electric drive apparatus according to claim 2,
wherein the left-side electric motor and the right-side electric motor are disposed to be spaced apart from each other in a direction of a first axis as the same axis that is substantially parallel to the width direction of the vehicle, and have respective output shafts that are located on the first axis,
wherein the left-side transmission mechanism and the right-side transmission mechanism are located between the left-side electric motor and the right-side electric motor in the width direction,
wherein the left-side rotary shafts include an input shaft, an intermediate shaft and an output shaft, while the right-side rotary shafts include an input shaft, an intermediate shaft and an output shaft,
wherein the gears disposed on the left-side rotary shafts include a drive gear, a large-diameter gear, a small-diameter gear and a driven gear, while the gears disposed on the right-side rotary shafts include a drive gear drive gear, a large-diameter gear, a small-diameter gear and a driven gear,
wherein the drive gear is disposed on the input shaft of each of the left-side transmission mechanism and the right-side transmission mechanism, which is located on the first axis,
wherein the input shaft of the left-side transmission mechanism is connected to the left-side electric motor in a power transmittable manner while the input shaft of the right-side transmission mechanism is connected to the right-side electric motor in a power transmittable manner,
wherein the large-diameter gear and the small-diameter gear are disposed on the intermediate shaft of each of the left-side transmission mechanism and the right-side transmission mechanism, which is located on a second axis parallel to the first axis, such that the large-diameter gear and the small-diameter gear are spaced apart from each other in a direction of the second axis, and such that rotation is transmittable to the large-diameter gear from the drive gear disposed on the input shaft,
wherein the driven gear is disposed on the output shaft of each of the left-side transmission mechanism and the right-side transmission mechanism, which is located on a third axis parallel to the first axis, and which is connected to a drive shaft in a power transmittable manner, such that rotation is transmittable to the driven gear from the small-diameter gear disposed on the intermediate shaft, and
wherein one of the input shaft and the output shaft of each of the left-side transmission mechanism and the right-side transmission mechanism constitutes a corresponding one of the pair of pump-drive rotary shafts.
