Abstract
In a hybrid drive apparatus, a first planetary gear mechanism transmits rotation of a first main shaft to which the engine driving force is inputted to a main speed-changing part at an equal speed due to engagement of a first clutch, and transmits the rotation of the first main shaft to the main speed-changing part and a first motor/generator at an increased speed due to engagement of a second clutch. This enables the range of gear ratios of the transmission to be extended and the degree of freedom in setting a gear ratio or a step ratio to be increased, and enhances the power generation efficiency by rotating the first motor/generator at a high speed without using a special speed increase device.
