Abstract
A cooling medium supply/discharge device includes a cylindrical rotary casing which is rotatable with a rotary shaft of the rotor; a cylindrical stationary casing fixed such that the stationary casing extends inward relative to the rotary casing and coaxially with the rotary casing, the stationary and rotary casings being relatively rotatable; a first stationary cylindrical body which is inserted into the stationary casing such that the first stationary cylindrical body is not rotatable; a first rotary cylindrical body which is inserted into the first stationary cylindrical body with a gap such that the first rotary cylindrical body is rotatable together with the rotary shaft; a second stationary cylindrical body which is inserted into the first stationary cylindrical body such that the second stationary cylindrical body is not rotatable; and a second rotary cylindrical body which is inserted into the first rotary cylindrical body and rotatable together with the rotary shaft.
