PROBLEM TO BE SOLVED: To smoothly return oil in a rotary electric machine casing to an oil pan disposed in the bottom part of a power transmission mechanism casing.SOLUTION: A hybrid vehicle driving device includes a rotary electric machine casing 36 for housing first and second rotary electric machines G and M, a power transmission mechanism casing 35 for housing a power transmission mechanism T, a partition wall 37 for partitioning the casings 35 and 36, an oil pan 38 disposed in the lower part of the power transmission mechanism casing 35, a strainer 39 disposed in the bottom part of the oil pan 38 and having an oil suction port 39a formed in its lower surface, an oil pump P for supplying oil scooped up via the strainer 39 to the first and second rotary electric machines G and M and the power transmission mechanism T, and a first opening 37c formed in the lower part of the partition wall 37 to return the oil of the rotary electric machine casing 36 to the oil pan 38. An inclined plane 32a is formed in the bottom part of the power transmission mechanism casing 35 to incline downward toward the oil pan 38, and the first opening 37c is positioned above the inclined plane 32a. |
