PROBLEM TO BE SOLVED: To provide an assembly method of a stator core of an enclosed electric compressor, in which an interference of a stator core by a motor housing is set to be large enough for preventing loosing of the stator core with respect to high internal pressure of refrigerant gas, compared with shrinkage fit or shrinkage and expansion fit. SOLUTION: Outer circumferential faces of first to third expanding parts 15b to 15d formed to the motor housing 15 are pressed inward in a radial direction of the motor housing 15 by two of upper and lower pressing tools 36, 37 to deform first to third interference parts 15e to 15g outward in a radial direction, the interference parts are held at positions separated from an outer circumferential face 32b of the stator core 32 when seen from an axial direction of the stator core 32, the stator core 32 is fit in the motor housing 15, and then the pressing by the tools 36, 37 are released. Therefore, the interference parts 15e to 15g are pressed to the outer circumferential face 32b of the stator core 32 with large interference, so that the stator core is securely tightened by the motor housing 15.
