DRIVE DEVICE FOR VEHICLE

WIPO Patent Application WO/2011/155277

A1

A drive device for a vehicle can appropriately supply a lubricating and cooling liquid to a rotor supporting bearing and a dynamo-electric machine, and the drive device can be obtained while an increase in the size of the case and an increase in manufacturing cost are minimized. A superimposed wall section (71) which is superimposed on a dynamo-electric machine is provided with a supply flow path (52) for allowing a lubricating and cooling liquid to flow therethrough and having formed therein a first supply section (31) as the supply section for supplying the lubricating and cooling liquid to a rotor supporting bearing (9) which supports the rotor (11a) of the dynamo-electric machine (11). The first supply section (31) is provided with a flow restricting section (31a) having a flow path cross-sectional area smaller than the flow path cross-sectional area on the upstream side in the direction of flow of the lubricating and cooling liquid. The supply flow path (52) is provided with a second supply section (32) which is located above the first supply section (31) and serves as the supply section for supplying the lubricating and cooling liquid to the dynamo-electric machine (11).
