| Zusammenfassung: | The invention relates to a rotor. A refrigerant having excellent cooling capacity is discharged equally or at any ratio on one axial side and the other axial side of a rotor. A rotor (10) is provided with: a shaft (12) which extends in the axial direction and through which a refrigerant passes; a rotor core (20) which is fixed to the shaft (12); a first end plate (50) which is positioned on one side of the rotor core (20) in the axial direction; and a second end plate (52) which is positioned on the other side of the rotor core in the axial direction. The rotor core is provided with a first flow path (22a) through which a refrigerant flows from one side in the axial direction to the other side in the axial direction, and a second flow path (22d) through which the refrigerant flows from the other side in the axial direction to the one side in the axial direction. The first end plate is provided with a first communication flow path (54a) through which the refrigerant flows from the axial first flow path and a f |
