Summary:PROBLEM TO BE SOLVED: To suppress variation in cooling performance of a rotor caused by liquid refrigerant.SOLUTION: By displacing a position in a rotor shaft direction of each refrigerant inflow port 18 relative to a position in the rotor shaft direction of each refrigerant discharge port 52 so that each refrigerant inflow port 18 formed in a rotor shaft 16 does not oppose in a rotor radial direction to each refrigerant discharge port 52 formed in a refrigerant supply shaft 50, liquid refrigerant discharged from the refrigerant discharge port 52 is not supplied directly to the refrigerant inflow port 18, but temporarily stored in a hollow portion 17 and then supplied to the refrigerant inflow port 18. This can suppress flow of the liquid refrigerant to be discharged from the refrigerant discharge port 52 from directly affecting flow of the refrigerant inflow port 18.SELECTED DRAWING: Figure 2 【課題】液体冷媒によるロータの冷却性能の変動を抑制する。【解決手段】ロータシャフト１６に形成された各冷媒流入口１８が冷媒供給シャフト５０に形成された各冷媒吐出口５２とロータ径方向に対向しないように、各冷媒流入口１８のロータ軸方向位置を各冷媒吐出口５２のロータ軸方向位置に対してずらすことで、冷媒吐出口５２から吐出した液体冷媒は、冷媒流入口１８に直接的に供給されることなく、中空部１７に一旦貯留されてから冷媒流入口１８に供給される。これによって、冷媒吐出口５２から吐出する液体冷媒の流れが冷媒流入口１８の流れに直接影響を及ぼすのを抑制することができる。【選択図】図２
