摘要： When a case of a rotary electric machine has an inner case member that houses a stator and an outer case member that houses the inner case member, a vibration that is transmitted from stator to the outer case member via inner case member is suppressed. The inner case portion is provided with a first tubular portion and a first protruding portion that protrudes toward a radial inner side from the first tubular portion on an axial first side. The outer case portion is provided with a second tubular portion and a second protruding portion that protrudes toward the radial inner side from the second tubular portion on the axial first side with respect to the first protruding portion. A coolant flow path is formed between the first tubular portion and the second tubular portion, and the first protruding portion and the second protruding portion are fixed to each other.

摘要： A vehicle drive device that includes the rotating electrical machine disposed at such a position that at least a part of the rotating electrical machine overlaps the speed change mechanism as viewed in a radial direction of the rotating electrical machine, and the rotating electrical machine disposed on the first side in the axial direction with respect to the input gear so as to overlap the input gear or a member that rotates with the input gear as viewed in the axial direction.
