PROBLEM TO BE SOLVED: To smoothly perform eccentric turning operation of a turning scroll to a fixed scroll. SOLUTION: A first separate turning shaft 10a and a second separate turning shaft 10b are eccentrically rotatably supported by a rotary shaft 7 of a motor 9 via bearings 11 and 12 of not receiving force in the thrust direction. A recessed part 31 is arranged on the separate turning shaft 10a, and a projection part 32 is arranged on the separate turning shaft 10b. The separate turning shaft 10a and the separate turning shaft 10b are connected only movably in the axial direction by engaging the recessed part 31 and the projection part 32. The fixed scroll 26a is fixed to a casing 1, and the turning scrolls 27a and 27b are installed on the separate turning shafts 10a and 10b. COPYRIGHT: (C)2008,JPO&INPIT
