PROBLEM TO BE SOLVED: To surely set a clearance between a housing in the axial direction of a rotating shaft and a rotor. SOLUTION: Circlips 50, 51 are fixed to rotating shafts 19, 20 on the rear housing 14 side. A ring-shaped adjusting spacer 48 is interposed between the circlip 50 and an inner ring 371 of a positioning radial bearing 37. A ring-shaped adjusting spacer 49 is interposed between the circlip 51 and an inner ring 381 of a positioning radial bearing 38. Clearance between housings for housing rotors 23-32 and the rotors 23-32 are adjusted with the adjusting spacers 48, 49.
