The rotor comprises: a fluid suction port 2a disposed on one end of a rotation axial line direction and sucking fluid; a fluid discharge port 2b disposed on the other end of the rotation axial line direction and discharging the fluid; and a fluid passage 2c for communicating the fluid suction port and the fluid discharge port. On a part of the fluid passage, a fluid acceleration part A inclined toward a direction separated from the rotation axial line as going to the other end of the rotation axial line direction is formed. The fluid discharge port is formed in a deviated state from the rotation axial line of the rotor. In addition, to the other end of the rotor, a drawing member 3 for guiding the fluid discharged from the fluid discharge port along the rotation axial line of the rotor and then discharging the fluid to outside is attached.
