Abstract

PURPOSE:To increase the thread-mount strength between a rotor and a rotary axis by using a metallic member having a high hardness and a low thermal conductivity for a joining part provided between the rotor and the rotary axis. CONSTITUTION:A rotor bottom 3c, which joins a rotor axis 3b and a cylindrical body 3a, is made of a member which has a high hardness and a low thermal conductivity, such as iron or molybdenum. Here, since the rotor axis 3b is made of molybdenum and the rotor body 3a is made of copper, the rotor bottom 3c prepared from iron or molybdenum is fixed to the rotor axis 3b and the rotor body 3a by soldering. By thus constituting the rotor bottom 3c, which becomes a joining part between the body 3a and the axis 3b, from iron or molybdenum, the bottom 3c and a rotary axis 4 are clamped with increased strength by means of a screw 5, and the screw 5 is securely prevented from loosening between the bottom 3c and the rotary axis 4.
