Abstract (en)

[origin: EP2426442A2] For providing a refrigerator coupling structure for enabling attaching/detaching and re-cooling of the refrigerator in a short time-period, by suppressing a heat movement from the refrigerator at the room temperature to an object to be cooled, which is cooled down to cryogenic temperature when attaching a cryogenic refrigerator thereon, while suppressing a volume of heat invasion into the object to be cooled, it has a heat contact portion (12,72) having a flexible portion (11) at least in a part thereof, which is coupled with a cold stage of the cryogenic refrigerator (1), wherein on an outer peripheral portion of this heat contact portion is provided a heat contracting ring (5), which has a heat contraction rate larger than that of the heat contact portion.
