PROBLEM TO BE SOLVED: To provide a tube pump with improved sealing performance by a simple structure. SOLUTION: The tube pump 1 is provided with a rotor 5 for holding both ends of a roller shaft 8 rotatably pivoting a roller 10 by urging both the ends in a predetermined direction by means of a U-shaped spring 9. In the tube pump 1, a rotor 5 is attached to a drive shaft 4 whose one end is opened. When the drive shaft 4 rotates the rotor 5, a tube T assembled between the rotor 5 and a tube guide 7 is sequentially pushed down and squeezed by means of the roller 10 . When the drive shaft 4 is not inclined, the outer peripheral face of the roller 10 is inclined from the tube guide 7 at a predetermined angle, and on the other hand, when the drive shaft is inclined, the outer peripheral face is in parallel with the tube guide 7.
