To suppress vibration transferred to a refrigerator main body, and reduce vibration and noise by fixing a fixing pin on the base plate of a refrigerator vertically, mounting the supporting leg of a compressor on a rubber vibration isolator which is brought in contact with the outer periphery of the pin, and abutting stoppers provided on one part of the supporting leg on the upper corner part of the vibration proof rubber.

A fixing pin 2 is fixed on the base plate 1 of a refrigerator main body vertically, and stoppers 3 are arranged on the supporting leg 5 of a compressor, and in lateral and longitudinal directions on a position where a circle is drawn around a hole 7 entered a rubber vibration isolator 6 erected one part of the stopper 3 downward. When the supporting leg 5 of a compressor is mounted on the flat surface of the upper part of the isolator 6, the stopper 3 abuts on the upper corner part of the isolator 6. When horizontal force is applied on the compressor 4, the stopper 3 abuts on the upper corner part opposing to horizontal force of the isolator 6, the isolator 6 is pushed, and thereby, the neck part of the isolator 6 is compressed by the fixing pin 2 and the supporting leg 5 so as to avoid deformation.
