PURPOSE:To make a coil not to move by force acting on a superconductive coil so as to prevent superconductive breakdown to be generated by abrasion heat by pressing a superconductive coil between a superconductive coil and an inner vessel incorporating a cooling medium and inserting a spring member to control a move of that coil. CONSTITUTION:A protective plate 10 is arranged on both end superfaces of a superconductive coil 1 of a superconductive coil device so as to protect the coil. Further, a sheet spring 11 as a spring in the shape of a sectional circular arc is inserted between the protective plate 10 and a supporting member 3. At this time, the coil 1 is so set up that pressing force may remain more than guide force even when the sheet spring 11 is restored by a thermal contraction difference so as to prevent the coil 1 from moving by a gap. Further, generation of superconductive breakdown due to abrasion heat is prevented while improving performance of a superconductive coil device to be loaded on a magnetic floating cart. |
