Summary:PROBLEM TO BE SOLVED: To provide a roller type infusion pump which reliably performs volumetric feeding of a fluid subject to infusion, constituted of members showing excellent chemical resistance, antifouling properties, and washing properties, is easily disassembled/assembled, and is easily maintained. SOLUTION: The roller type infusion pump is equipped with a resilient and crushable infusion tube 4, a stator 5 disposed on a pump housing 1, a rotor 7 which makes a shaft 11 of a stepping motor 10 rotating forward and reversely at least a part of a rotary shaft 12 and integrally rotates with the shaft 11, a plurality of rollers 13 which are rotatably disposed at regular intervals in the circumference at an equal distance from the rotating shaft 12 to respectively crush the infusion tube 4 between the stator 5 and the roller 13 depending on the rotations of the rotor 7, and a micro-step driver 21 controlling to drive the stepping motor 10.
