ABSTRACT:
A vehicle drive apparatus includes a first electric motor, a power distributing mechanism, a second electric motor, and a step-variable power transmission. A power transmitting portion includes a second case, accommodating the second electric motor and the automatic power transmission. One end of an input shaft of the automatic power transmission faces a drive apparatus output shaft, which is supported with a first support wall mounted on the second case, the second electric motor being accommodated in a compartment opposite to the automatic power transmission with respect to the first support wall, and one end of a second rotor supporting shaft of the second electric motor faces the automatic power transmission, which is supported with a second support wall mounted on the second case. The automatic power transmission and second electric motor can be unitized as one power transmitting portion, improving assembling workability of the drive apparatus.
