Abstract
A rotating electric machine includes a tube-shaped outer housing and a tube-shaped inner housing that forms a coolant flow channel between the outer housing and the inner housing. The inner housing is fixed with the outer housing by press-fitting or shrink-fitting at one end thereof in its axial direction and fastened with the outer housing at another end by plural bolts. One or more non-contacting sections, in which an inner circumferential surface of the outer housing and an outer circumferential surface of the inner housing are not in contact with each other, are formed at a fixation portion made by the press-fitting or the shrink-fitting between the outer housing and the inner housing along a circumferential direction thereof.
