Zusammenfassung:	PROBLEM TO BE SOLVED: To facilitate the precise positioning of a frame main bearing part and a stator annular passage and the precise positioning of a main bearing and a sub-bearing by using a reference bar and a plurality of collet chucks arranged so as to be concentric to it. SOLUTION: A reference guide bar 26 is inserted so as to extend through a frame main bearing part 22 and a stator annular passage 21 within the casing 2 of a compressor, and a frame 8 is pressed by the reference guide bar 26 and fixed. A plurality of collet chucks 25a and 25b arranged so as to be mutually concentric by the reference guide bar 26 are used to position the frame main bearing part 22 and the stator annular passage 21 so as to be mutually concentric, and the frame 8 is fixed in this state by welding or the like. Thereafter, the reference guide bar 26 is pulled out, and the rotor of a motor part is fitted and fixed by shrinkage fit.
