PROBLEM TO BE SOLVED: To provide a scroll fluid machine capable of efficiently compressing gas to be compressed. SOLUTION: Fixed scrolls 2 and 3 are fixed to a casing 1, a stator 4 is fixed to the casing 1, a rotary shaft 7 is rotatably supported by the casing 1, and a rotor 8 is fixed to a rotor fixing part 7a of the rotary shaft 7. A turning shaft supporting part 7b is provided on one end of the rotor fixing part 7a of the rotary shaft 7, the turning shaft 11 is eccentrically and rotatably supported by an inner circumferential surface of the turning shaft supporting part 7b, and turning scrolls 12 and 13 are mounted on the turning shaft 11. The turning scrolls 12 and 13 are respectively located outward of an end on the opposite side of the turning shaft 11, the turning scrolls 12 and 13 are located on the turning shaft supporting part 7b side, and a rotation preventive means to permit the eccentric turn of the turning shaft 11 and prevent the rotation of the turning shaft 11 is provided.
