Driving apparatus

There are provided a generator-motor arranged on a first axis line, a drive motor arranged on a second axis line in parallel with the first axis line, a driving apparatus case for containing the generator-motor and the drive motor, an inverter for the generator-motor and the drive motor and a smoothing condenser for smoothing power source voltage of the inverter. The inverter is attached to the driving apparatus case to dispose diameter directions of the generator-motor and the drive motor and the smoothing condenser is attached to inside of the driving apparatus case to project an end portion thereof. The inverter can be integrated to the driving apparatus case as a sub assembly. By the invention, the driving apparatus can be downsized, and wirings can be simplified.
