摘要： In cryogenic refrigerator provided with a cryostat having a low temperature level maintaining part for cooling and maintaining a part to be cooled at a very low temperature level and an expander which is fitted in the low temperature level maintaining part of the cryostat and generates cold in the low temperature level maintaining part by expanding refrigerant gas compressed by a compressor, vibration of the working expander is prevented from being transmitted to the part to be cooled by fixing and supporting the part to be cooled to the cryostat, separately from the expander, thereby minimizing the bad influence or vibration on a cryogenic working apparatus which is sensitive to vibration and by integrally supporting the part to be cooled and the expander to the crystat. In this way, the necessity of supporting the part to be cooled and the expander individually is eliminated and installation of the refrigerator is easy.
