Abstract
A vehicle drive apparatus includes a motor generator, a speed reduction mechanism connected to a rotor shaft of the motor generator, an output shaft connected to the speed reduction mechanism, an intermediate wall separating the motor generator from the speed reduction mechanism, and a bearing that is fixed to the intermediate wall and supports the rotor shaft. The motor generator, intermediate wall, speed reduction mechanism, and output shaft are disposed in this order, and a ring gear of the speed reduction mechanism is fixed. The ring gear is fixed to the intermediate wall via a ring gear flange that is positioned relative and fixed to the intermediate wall by a centering mechanism and a locking mechanism. The centering mechanism is formed by fitting a boss of the ring gear flange and the intermediate wall. The locking mechanism is disposed on an outer peripheral side relative to the centering mechanism.
