た。 In a nuclear fusion device that operates as described above,
The heat-insulating support legs 4 and 6 that support the center column 3 and toroidal coil 5 are both made of a highly heat-insulating material because it is necessary to heat-insulate the center column 3 and toroidal coil 5, which are at extremely low temperatures, and the base 1, which is at room temperature. structure 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.

た。 Since the conventional nuclear fusion device is configured as described above, when an earthquake or the like occurs, the inertial force generated in the center core 3 and the toroidal coil 5 causes the heat insulating support legs 4 and 6 that support these to resist shearing. received,
Excessive stress is expected to occur. 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 requirement for heat-insulating properties. 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.

Even if inertial force is generated in the center column 3 and toroidal coil 5 due to an earthquake, etc., and a large external force acts on the insulating support legs 4 and 6 that support them,
The second heat-insulating support leg 9 provided in the radial direction of the center column 3 receives this external force, and the other heat-insulating support legs 4 and 6
It is possible to prevent excessive shearing force from acting on the Further, according to this embodiment, since the base 1 having the recess 1a is used and a part of the center column 3 is inserted into the recess 1a, the toroidal coil heat insulating support leg supports the toroidal coil 5 directly on the base 1. 6 is inevitably reduced, and the radial rigidity of this heat-insulating support leg 6 is equivalently improved.
