PROBLEM TO BE SOLVED: To provide a tube pump, eliminating the need for an occupied space when opening a cover by disusing a sliding or rocking upper cover provided on a rotor of the tube pump, achieving safe and easy handling operation when mounting or demounting a tube, and securing conveniences in sanitary management by allowing easy cleaning in the pump. SOLUTION: The soft tube 7, which is stored between side width limiting rollers 34, 34 provided at a plurality of upper and lower positions on the outer periphery of the rotor 5, is located along the outer peripheries of rotors 6, 6. The rotor 5 is guided into a fixed wall 13 along a spiral guide groove 11 formed in the outer periphery of a driving shaft 12 of a motor 3. Thereby, the tube 7 is pressed between the fixed wall 13 and each of the rollers 6, 6, in the state of which an upper cover 15 of the rotor 5 closes the inner periphery of the fixed wall 13.
