PROBLEM TO BE SOLVED: To provide a squeeze type pump dispersing damage generated on a pumping tube and making determination of rotation timing unnecessary by rotating the pumping tube around a canter axis direction not manually without applying unnatural force. SOLUTION: A pumping tube 3 is bent and installed in a cylindrical pump case 2. A roller 5 pressing the pumping tube 3 to an inside of the bending is provide. The roller 5 is inclined to a tube center axis direction and is inclined to an inner circumference surface of the pump case 2. The roller 5 is rolled in a tube center axis direction to deliver fluid sucked from one end of the pumping tube 3 to another end. The pumping tube 3 gradually rotates around the center axis direction by only operating the squeeze type pump 1. COPYRIGHT: (C)2007,JPO&INPIT
