PURPOSE:To save the consumption of a refrigerant in a liquid reservoir part inside a winding mounting shaft. CONSTITUTION:A support piece 21 which protrudes to the outward direction is bonded to a midstream part 16b in a refrigerant discharge tube. A support- piece receiver member 22 which is faced with the support piece 21 is bonded to the inner circumferential face of an inside tube 4b for a winding mounting shaft. When a rotor is turned, the midstream part 16b in the refrigerant discharge tube is deformed elastically by a centrifugal action due to the own weight of the support piece 21, and the support piece 21 comes into contact with the support-piece receiver member 22. |
