Zusammenfassung:PURPOSE:To abate any noise by a method wherein a holding means holding a containing vessel of a refrigerator and a body to be refrigerated in adiabatic vessel is integrated with a part of a component excluding the adiabatic vessel using a rigid coupling means. CONSTITUTION:An expanding device 10 is completely tightened up on a magnetic shield main body 17 using a rigid coupling means such as a bolt through the intermediary of a flange 18 and then integrated with a vacuum vessel 7 through the intermediary of a bellows 19 as an elasticity holding means and the flange 18. A load holding body 20 integrates multiple cylindrical bodies 22 with the protrusions of a liquid helium vessel using a bonding agent, etc., while the other end of the load holding body 20 is integrated with the magnetic shield body 17 while the room temperature end is integrated with a rod 24 completely tightened up by a bolt, etc., using the bonding agent, etc. Through these procedures, the oscillation of the expanding device 10 is absorbed in the magnetic shield body 17 not to be transmitted to the vacuum vessel 7, thereby enabling the noise to be abated.
