PURPOSE:To enable the composition of a reinforcing member out of a thin plate and to contrive the lightness in weight and high efficiency by retaining a distribution loading acting in a croll-sectional direction of a coil not by the bent of the reinforcing member, but by a tension of that. CONSTITUTION:The lateral cross-sectional shape of a superconductive coil 11 shows a trapezoid as a superconductive wire 11a is wound on a periphery of that. On the wire, a resin member 11b of a curved shape is formed by curing with epoxy resin including a reinforcing member such as a glass tape. The curved shape is an arc, combination of arcs, combination of an arc and a straight line or an ellipse. An inner container 12 has the shape fitting a peripheral surface of the coil and is in a tight contact with that surface. A supporting member 13 for supporting the coil 11 has a concave shape 11 order to support only side surfaces and an inner circumferential surface of the coil. Between the coil outer and inner circumferential surfaces and the supporting member 13, a spacer 15 which is slippy such as polyimide is inserted. Consequently, for the inner container 12, merely a tension is needed to be considered and it can the composed out of a thin plate resulting in the lightness in weight. |
