PROBLEM TO BE SOLVED: To provide a roller pump which eliminates the generation of beating sounds when rollers for pressing a tube are separated from the tube while facilitating the mounting of the tube between the rollers and the stators of the roller pump. SOLUTION: A shaft hole 24 provided on a rotor 5 for bearing spindles 23 of the respective rollers 6 present a shape of a slot longer in the radial direction of the rotor 5 and the spindles 23 of the individual rollers 6 are each held with a U-shaped plate spring 27 for supporting the upper and lower part of the spindle while the central part of the side part of the plate spring is supported toward the center side of the rotor 5. On the other hand, the surrounding wall of the stator 7 for pressing the tube T facing the turning rollers 6 are so formed in shape as to be curved sharp C1 at the location of starting the pressing of the tube T and to be inclined C2 longer enough to cover the range from the start of loosening the pressing of the tube T to the complete its opening as compared with the range of the sharp curve at the start of the pressing. This can eliminate the generation of beating sounds when the rollers 6 are separated from the pressing of the tube T. COPYRIGHT: (C)2007,JPO&INPIT
