Abstract
A hybrid drive apparatus includes: a drive power source that includes an internal combustion engine, a first electric motor, and a second electric motor; a power transmission mechanism that includes a carrier, a sun gear, and a ring gear, and that is configured to rotate the output shaft of the internal combustion engine by the first electric motor; and plural bearings that each includes an outer ring member and an inner ring member fitted to the outer ring member through a rolling element, and that are provided apart from each other in an axial direction of the output shaft with the carrier being positioned between the bearings. An inner periphery of the outer ring member is positioned more inward in a radial direction of the ring gear relative to a meshing portion between inner teeth of the ring gear and outer teeth of one of the pinion gears.
