Abstract
A case body that is integrally formed so as to form a first housing chamber including a rotary electric machine housing chamber that houses a rotary electric machine and a gear housing chamber that houses a plurality of gears and second housing chamber that houses an inverter device includes a peripheral wall portion that surrounds an outer side of rotary electric machine and gears in radial direction, partition wall that partitions first and second housing chambers, and a partition member disposed between the rotary electric machine housing chamber and the gear housing chamber. The partition wall is formed on both sides in an axial direction across partition member so as to extend in axial direction from a position where partition wall overlaps rotary electric machine on outer side in radial direction to a position where partition wall overlaps at least one of the gears on outer side in radial direction.
