PURPOSE: To provide a highly durable tube pump by which fluid does not remain in a tube when pump operation is stopped.

CONSTITUTION: A space part 103 where a cross-sectional shape in the specific direction of an inside surface 104 is formed as a circular arc surface running at least over a prescribed angle range, is formed inside of a main body 102. A support frame 12 is arranged in the space part 103, and can rotate with the axis L as its center. A tube 118 is formed of an elastic material, and is laid over a prescribed angle range at least in the circumferential direction along the inside surface. Rollers 120 are separated from each other by an angle of not more than a prescribed angle in the circumferential direction to the axis L of the support frame 12, and are arranged in a plurality, and can contact/ separate freely with/from the axis L of the support frame 12, and move in the direction for separating from the axis L of the support frame 12 by centrifugal force when the support frame 12 is rotated. When the support frame 12 is rotated, at least a single roller 120 moves while crushing the tube 118 between the outer peripheral surface and the circular arc surface, and sends out fluid in the tube 118.
