generated in the upstream portion of the tube and a pump non-operating position wherethe negative pressure is not generated, and a rack member including a plurality of teeth,wherein the pressing member is provided with a pinion member capable of continuouslyengaging with the a flexible portion of the rack member when the pressing memberrotatably moves between the pump non-operating position and the pump operatingposition.
