<p>PROBLEM TO BE SOLVED: To make a tube to be easily replaced and to reduce a load due to pulling of the tube by a simple structure in a tube pump.SOLUTION: A tube pump 1 comprises: a fixed circular member 2; a tube 3 which is arranged on its inner wall surface 2a; and first and second free movement circular members 7, 8 to which torque is given from a rotor 6. Since the tube 3 is closed to the inner wall surface 2a of the fixed circular member 2 by pressure by the first and second free movement circular members 7, 8, the tube 3 can be closed by pressure by a few components, in addition, it is only necessary to arrange the tube 3 between the circular inner wall surface 2a and the first and second free movement circular members 7, 8 in tube replacement, a complicated operation for winding the tube 3 in the U-shape along a ring is not required. Thus, it becomes easier to replace the tube by a simple structure. In addition, since the tube 3 is only pushed to the inner wall surface 2a and is not pulled in one direction, a load to the tube 3 can be reduced.</p> |
