PURPOSE:To rigidly hold a superconductive field coil in a simple structure without using a retaining ring by retaining a superconductive field coil at a notch formed at the tees of a coil mounting shaft by a retainer. CONSTITUTION:A slot 18 formed at a coil mounting shaft 2 is formed of a linear portion 18a, an arc portion 18b, and a corner 18c, and a notch 24 is formed at the tees 23 of the shaft 2 adjacent to the corner 18c of the slot 18. A supporting member 25 is disposed adjacent to the coil 3 at the notch 24, the shaft 2 is secured by a clamp 26, a retainer 27 is disposed on the member 25, and the shaft 2 is secured to press a wedge 15 radially. Thus, the coil 3 can be rigidly held. |
