Abstract
In a drive assembly of the invention, a first catch tank is provided above a casing that keeps lubricating oil accumulated in a bottom thereof for immersion of part of a rotor of a motor MG3 and of part of a differential ring gear of a differential gear. The first catch tank temporarily keeps the lubricating oil scooped up from the bottom of the casing by the rotation of the differential ring gear. The lubricating oil kept in the first catch tank is flowed down by the force of gravity and is fed to peripheral bearings. A second catch tank is arranged to temporarily keep the lubricating oil scooped up from the bottom of the casing by the rotation of the rotor of the motor MG3. The lubricating oil kept in the second catch tank is flowed down by the force of gravity and is fed to peripheral bearings. This arrangement desirably shortens oil paths connecting the respective catch tanks to the peripheral bearings and ensures smooth supply of the lubricating oil to all the peripheral bearings and other oil-requiring sites.
