PURPOSE:To obtain a rotor having thermal stability and less vibration by providing a thermal shortcircuit member flexible with respect to a slide and fixedly welding it to both a torque tube and a low temperature damper. CONSTITUTION:A thermal shortcircuit unit 18 for thermally connecting a low temperature damper 5 and a torque tube 2 is provided, and is formed of a part 18A secured to the tube 2 at the welded part 20 and a flexible member 18B disposed between the part 18A and the damper 5. The member 18B is deformably formed in the range allowable in the strength by following up the movement of a slide contacting member 17 secured at both ends to the damper 5 and the part 18A at the welded part 19. Since the thermal resistance of the thermally shortcircuit part 18 can be unitarily determined by the size and shape of the part 18 in this manner, stable heat tansfer phenomenon occur, finally balancing temperature approaches extremely the temperature of the other end, the cooling performencee of the rotor can be stablilized and thermal vibration will not resultantly occur. |
