PROBLEM TO BE SOLVED: To provide a tube pump capable of preventing fluid from flowing backwards. SOLUTION: In the tube pump 1, a rotor 5 rotatably holding a plurality of rollers 9 is rotated with a motor 3 in the positive direction K1, a tube 7 in which fluid flows is successively pressed with the rollers 9, and the liquid is fed under pressure by a certain quantity. A link mechanism for moving the position of the axle center of a rotor 5 in the direction being spaced from the tube 7 is provided when the rotor 5 is rotated in the reverse direction K2 with the motor 3.
