PURPOSE:To prevent the thermal deformation of a helium supplying and exhausting unit material in a superconductive rotor by forming a gas recovery pipe to pass a gas recovery hole partly formed in a slip ring, and recovering evaporated gas through the slip ring. CONSTITUTION:A gas recovery pipe 28a is partly formed to pass gas recovery holes 31 formed at slip rings 20a, 20b thereby recovering the evaporated gas through the rings 20a, 20b. The hole 31 is formed of circumferential recovery holes 31a formed circumferentially at the axial end side in the rings 20a, 20b and axial recovery holes 31b communicating between the circumferential recovery holes 31a. |
