PROBLEM TO BE SOLVED: To provide a tube type pump device, simplifying the structure and improving the reliability by adopting a structure dispensing with a following turn preventing mechanism using a spring. SOLUTION: In this tube type pump device, when a rotor 40 is rotated, rollers 71, 72 put in the refuge position are displaced to crushing positions when passing cam parts 31, 51, and in this displacement state, the rotor 40 is rotated and moved. Therefore, the crushing portions of an elastic tube 60 caused by the rollers 71, 72 are displaced so that a fluid in the elastic tube 60 is extruded. COPYRIGHT: (C)2005,JPO&NCIPI
