PURPOSE:To obtain a heat insulator supporting device in which a heat insulator support can be replaced without disassembling a cooler at the time of damage of the support by providing a hook at any of coupling parts between the support of the part of components of the device and the mounting seat and the support of a cryogenic temperature tank. CONSTITUTION:A heat insulator support 21 rotatably pin-coupled by a pin 18 to the inner end of a supporting rod 7 which has at its one end a hook 21a to be engaged with a coupling part such as a pin part 22 and forms at the other end a supporting part 16 is provided at a mounting seat 6 provided at the sidewall of a helium tank 3 of a cryogenic temperature tank. This device can be mounted, after an upper vacuum tank and a lower vacuum tank are assembled, by mounting the support 21 out of the vacuum tanks at the tank of the hook coupling part installing side. |
