PROBLEM TO BE SOLVED: To provide a tube pump which is a structure of a pump capable of materializing safe and easy handling operation when mounting and removing a tube, wherein cleaning of the inside of a pump can be facilitated by removing a pump body while enabling regular and reverse rotation of a rotor. SOLUTION: The guide protrusion 27a of a cylindrical hole 26 in a rotor 5 follows a spiral guide groove 4a of a driving shaft 4 so that the rotor 5 is accommodated in the fixed wall 9 in such a manner as to be rotated. The motor 3 is driven forward, which enables regular rotation of the rotor 5. With a lateral shaft 33 in a gripping knob 7 locked in a coupling groove formed by aligning the top end groove 28 of the driving shaft 4 and the top end groove 29 of a cylindrical part 25, the motor 3 is reversely driven, which enables reverse rotation of the roller 5. By displacing the gripping knob 7 upward, the rotor 5 can be removed upward from the driving shaft 4 of the motor 3 by the reverse rotation drive of the motor 3. COPYRIGHT: (C)2004,JPO
