PURPOSE:To readily hold a superconductive field coil with a simple structure by forming a slot on the surface of a coil mounting shaft, and containing the coil in the slot, and then inserting a wedge into the slot. CONSTITUTION:A superconductive field coil 3 is initially contained at its linear portion 31 and an arc portion 32 in a slot 23, and then contained at the corner 33 in the slot 23, thereby associating in the slot 23. Then, a wedge 24 is inserted into the slot 23 to rigidly hold the coil 3. Accordingly, since the insulating filler of the periphery of the arc portion 32 and the corner 33 of the coil 3 can be eliminated, no gap is produced around the coil 3 due to the thermal contraction of the filler, thereby preventing the coil 3 from moving during operation. |
