3) and the insulating support legs (4) and (6) that support the toroidal coil (5), it is necessary to insulate and connect the cryogenic center column (3) and toroidal coil (5) to the normal temperature base (1). Since then, a heat-insulating structure using highly heat-insulating materials has been adopted. However, this heat insulating structure was designed so that both the heat insulating and supporting properties were approximately satisfied, since if too much priority was given to the heat insulating properties, the mechanical strength and rigidity for support would be impaired.

In the event of an earthquake, the insulating support legs (4) and (e) that support the central column (3) and toroidal coil (5) will be subjected to shear due to the inertial force generated in the central column (3) and toroidal coil (5), and excessive stress is expected to occur. Ru. In order to reduce this stress, it is effective to increase the rigidity of these heat insulating support legs (4) and ' (6), but it is difficult to sufficiently increase the rigidity with the current structure due to the above-mentioned heat insulation requirements. . Therefore, in conventional devices, seismic performance is ensured by adding a reinforcing structure to support the toroidal coil (5), which has disadvantages such as a complicated structure and high cost.
