PROBLEM TO BE SOLVED: To provide a tube pump which is superior in quietness without generating shock sounds. SOLUTION: In a non-pressure contact state of rollers 43a and 43b to a flexible tube 51, a projecting part 55a is set to a roller guide 55, whereby a frictional force is generated between the rollers 43a, 43b and the projecting part 55 and between a pump wheel 42 and the rollers 43a, 43b. Both end faces of each of the rollers 43a and 43b outside a contact region to the flexible tube 51 contact the projecting part 55a and the pump wheel 42, resulting in prohibiting roller shafts 43a1 and 43b1 from freely moving inside roller support grooves 42a and 42b. |
