Abstract
A drive apparatus for a hybrid vehicle is provided with a first motor generator, a power splitting mechanism portion, and a second motor generator. The first motor generator functions mainly as a generator. The power splitting mechanism portion divides the power generated by the engine into power for the first motor generator and power for driven wheels. The second motor generator has an outside diameter that is smaller than the outside diameter of the first motor generator and is arranged on the side of the first motor generator opposite the engine. Further, a speed reducing mechanism portion which has an outside diameter smaller than the outside diameter of the second motor generator and which reduces the rotation speed of the second motor generator is provided on the side of the second motor generator opposite the engine.
