Abstract: Disclosed is a compressor including a housing, and a motor including a stator to be interference fitted into and fixed to an inner circumferential surface of the housing and a rotor rotatable inside the stator. The stator includes an annular back yoke disposed inside the housing, a plurality of teeth extending radially inward from the back yoke, and a coil wound on the plurality of teeth. The back yoke includes a deformation portion compressed and deformed by the housing while the stator is interference fitted into the inner circumferential surface of the housing, a contact portion which protrudes radially outward from the deformation portion and being in contact with the housing, and a cavity formed on a radial inner side of the deformation portion into which which the deformation portion is deformed.
