PURPOSE:To improve reliability by providing plural stages of key grooves horizontally to the inside circumferential side of wedge-supported troidal magnets and fixing the troidal magnets to each other by means of toric key members. CONSTITUTION:Plural stages of the horizontal key grooves 9 are formed on the inside circumferential side of the troidal magnetic 2 formed with edges 8 and the respectively toric keys 10 are fitted into the key grooves 9. The magnets 2 are fixed to each other by the members 10 and the generation of vertical movements in the magnets 2 is obviated. Reliability is, therefore, improved without inducing quenching of a superconductive coil.
