1. A compressor comprising:
a housing; and
a motor including:
a stator configured to be interference fitted into and fixed to an inner circumferential surface of the housing, the stator including an annular back yoke, a plurality of teeth extending radially inward from the annular back yoke, and a coil wound on the plurality of teeth, and
a rotor configured to be rotatable inside the stator,
wherein the annular back yoke comprises:
two cantilevers extending opposite to each other in a circumferential direction of the annular back yoke from a center of each of the plurality of teeth; and
two cavities formed on a radial inner side of the two cantilevers into which the two cantilevers are deformed,
wherein each of the two cantilevers comprises:
a deformation portion pressed and bent by the housing while the stator is interference fitted into the inner circumferential surface of the housing; and
a contact portion which protrudes radially outward from the deformation portion and being in contact with the housing while the stator is interference fitted into the inner circumferential surface of the housing.
