PROBLEM TO BE SOLVED: To unnecessitate a work for reversely rotating a blood pump for the backward flow of a dialyzing liquid in priming, strictly adjusting the flow rate of the dialyzing liquid by the blood pump, and removing a member for crushing a blood tube from the rotating means of the blood pump. SOLUTION: The dialyzer is constituted such that a movement housing 32 is stopped at an open position when priming is started, and the blood tube 7a is prevented from being crushed between the movement housing 32 and the rotating means 34 when the dialyzing liquid is allowed to flow into a blood passage 4 from a dialyzing liquid passage 3 while the housing 32 is stopped at the open position. For this reason, the dialyzing liquid flows over the blood pump in the blood tube. When the movement housing 32 is positioned at a liquid feeding position afterward, so as to open an opening/closing clamp 15, the dialyzing liquid is allowed to flow toward a blood tube 7b on a downstream side.
