PROBLEM TO BE SOLVED: To provide a compressor with small vibration and small noise capable of improving torque density and preventing center dislocation and whirling. SOLUTION: The inner peripheral side of a first rotor supporting part 34 is fixed on a rotating shaft between a stator 36 and a compression mechanism part 2, and an end part of the side of the compression mechanism part 2 of a rotor 31 is fixed on the outer peripheral side. The outer peripheral side of a second rotor supporting part 35 is fixed on an end part on the opposite side of the compression mechanism part 2 of the rotor 31. A part of a fixed shaft is inserted into a through hole 35a of the second rotor supporting part 35, the opposite side of the side of the compression mechanism part of the fixed shaft 7 is fixed on a closed container 1, and the stator is fixed on the side of the compression mechanism part 2 rather than the second rotor supporting part 35 of the fixed shaft 7. The second rotor supporting part 35 is supported free to revolve by a fixed shaft side bearing 41 provided on the fixed shaft 7, and the rotating shaft 4 is supported free to rotate by a rotating shaft side bearing 42 provided on the side of the compression mechanism part 2 rather than the fixed shaft 7.
