Abstract
A rotating electric machine includes an inner housing and an outer housing. An inner circumferential surface of the outer housing includes a first cylindrical surface contacting first sealing member, a second cylindrical surface contacting a second sealing member, and a third cylindrical surface in which an end part of the inner housing is press-fitted into. The second cylindrical surface has a smaller diameter than the first cylindrical surface and the third cylindrical surface has a smaller diameter than the second cylindrical surface and is provided closer to the bottom than the second cylindrical surface. The first sealing member contacts the first cylindrical surface and the second sealing member contacts the second cylindrical surface to form a gap in an axial direction between the end part of the inner housing and the third cylindrical surface where the inner housing has been inserted into the outer housing.
