A field rotor (100) of a superconducting rotating machine including: a rotation shaft (18); a supply shaft (10) that supplies a refrigerant to the rotation shaft at one end of the rotation shaft; an input/output shaft (24) provided at the other end of the rotation shaft so as to integrally rotate with the rotation shaft; and a superconducting coil (20) held on a circumferential surface of the rotation shaft to be cooled by the refrigerant, wherein the supply shaft and the input/output shaft are fixed to each other so as to rotate integrally with each other, and the rotation shaft and the supply shaft are at least partly brought in contact with each other in order to allow the rotation shaft to be supported by the supply shaft and in order to be slidably fitted to each other in a circumferential direction of the rotation shaft and in an axial direction of the rotation shaft. |
