Abstract
An electric compressor includes a stator housing 7 in a cylindrical shape having one end opened, and a rear casing joined to an opening of the stator housing via a gasket. The stator of an electric motor is housed from the opening of the stator housing, and fixed to an inner surface of the stator housing by shrink fitting. The electric compressor includes a plurality of shrink-fit fixing surfaces 42 which is formed on the inner surface of the stator housing 7 and to which the stator is fixed, a gasket sealing surface 7B which is formed on an opening end surface of the stator housing 7 and on which the gasket is disposed, and a plurality of ribs 49 which is formed on an opening side of an outer surface of the stator housing corresponding to the shrink-fit fixing surfaces.
