PROBLEM TO BE SOLVED: To provide a tube pump which prevents deterioration of feeding capacity by forcibly restoring a tube. SOLUTION: The direction for crushing the tube 130 by rollers 112, 116 is different from the direction for crushing the tube by a roller 114. For example, the section crushed by the roller 114 is then crushed by the roller 116. That is, the tube 130 crushed from one direction is also crushed from the other direction. Thus, the tube 130 is crushed from the multi-directions, and the tube 130 can be forcibly restored as well as restored by its elasticity (restoration by elasticity) so that the tube 130 crushed from one direction is crushed from the other direction. Consequently, the tube pump 51 preventing deterioration of the feeding capacity used for a long period can be obtained. COPYRIGHT: (C)2009,JPO&INPIT
