PURPOSE:To enable reducing the thickness of a container member by mechanically or metallurgically jointing a coil support member for supporting a superconducting coil to the container member provided along the direction wherein the electromagnetic force generated by the superconducting coil mutually affects. CONSTITUTION:The mutually attracting electromagnetic force between superconducting coils 7, 8 is affected to an upper plate 3 and a lower plate 4 since the coil support members 11, 12 for supporting each superconducting coil 7, 8 are jointed to the upper plate 3 and the lower plate 4 of container members provided in parallel along the direction wherein the electromagnetic force generated by each superconducting coil 7, 8 mutually affects. In this case, the thickness of all the members of a cryogenic refrigerant container 5, especially that of an inner cylinder 1, can be reduced since the upper plate 3 and the lower plate 4 have high rigidity against the electromagnetic force. This can reduce not only the weight of the cryogenic refrigerant container 5 but also can miniaturize the whole of the cryogenic refrigerant container 5. |
