PURPOSE:To obtain high vibration isolation performance by providing a vibration isolator reciprocatably supported in the axial direction coaxially with a compression piston and a linear motor type driving mechanism reciprocatingly driving the vibration isolator, and reciprocating the compression piston and the vibration isolator so as to negate the vibration generating force caused by the movement of moving section masses. CONSTITUTION:The reciprocating compressor 20 or a refrigerator has a compression piston 1 reciprocated when an AC power source is connected to a linear motor type driving device 15 constituted of a solenoid coil 5 and a permanent magnet 2 and compresses an operating medium in a compression space 8. A vibration isolating device 30 provided on the compressor 20 is constituted of a vibration isolator 301 supported coaxially with the piston 1 and a linear motor type driving mechanism 315 reciprocating the vibration isolator 301. The ratio in magnitude between signal outputs of a compression piston position detector 201 and a vibration isolator position detector 309 is set to be equal to the reciprocal ratio between moving section masses of the compression piston 1 and the vibration isolator 301, and the compression piston 1 and the vibration isolator 301 are reciprocated fact to face.
