を得ることができる。[Effects of the Invention] The present invention includes a slot formed in the through hole and coil mounting shaft as described above, which is composed of a straight part, an arc part, and a corner part, and a notch is formed in the teeth of the coil mounting shaft adjacent to the corner part of the slot. A support member is placed adjacent to the superconducting field coil in this notch and fixed to the coil mounting shaft by a tightening member, and a presser foot is placed on the support member to tighten the wedge in the radial direction. Since it is fixed to the coil mounting shaft so as to be pressed inward, the superconducting field coil can be firmly held with a simple structure without using a retaining ring.
Furthermore, it is possible to obtain a highly reliable rotor of a superconducting rotating electric machine in which a pre-wound superconducting field coil can be easily incorporated.
