PROBLEM TO BE SOLVED: To provide a field rotor of a superconductive rotary machine which can cope with a request for securing a function to effectively cool a superconductive coil, and a request for securing mechanical strength to transmit torque between the superconductive coil and an input/output shaft more easily than a conventional technique.SOLUTION: A field rotor 200 of a superconductive rotary machine includes: a rotary shaft 18; a supply shaft 10 which supplies a coolant to the rotary shaft 18 on one end of the rotary shaft 18; an input/output shaft 24 which is provided integrally with the rotary shaft 18 on the other end of the rotary shaft 18; and a superconductive coil 20 which is held on a peripheral surface of the rotary shaft 18 and cooled by the coolant. The supply shaft 10 and the input/output shaft 24 are fixed to each other so that they are integrally rotated. At least parts of the rotary shaft 18 and the supply shaft 10 are brought into contact with each other so that the rotary shaft 18 is supported by the supply shaft 10, and the rotary shaft 18 and the supply shaft 10 are fitted to each other so as to be slidable in a circumferential direction of the rotary shaft 18 and an axial direction of the rotary shaft. |
