PURPOSE:To perfectly seal a fluid, by arranging a rotor in a stator through a gap and rotating the same by flowing in a fluid from one side of the gap. CONSTITUTION:When a motor 17 is operated to rotate a gear 19 around an axis O1, the gear part 14G of a stator 7 also rotates around an axis O2. A rotor 9 is also rotated around the axis O2 by the rotation of the gear part 14G and the repulsion of the magnet provided in the rotor 9. At this time, blood is sent into the tube T1 of the fluid inflow screw terminal 10 of a centrifugal separator from a blood receiving sample cup SC by the operation of a pump P1 and subsequently enters the gap 8 between the inner wall of the stator 7 and the rotor 9 to receive centrifugal force in the inner wall direction of the stator 7. Because of this, difference in flowability is generated between a blood-clot component and a serum component in the gap 8 and the blood-clot component can be sent to a reaction system.
