Claims

[Claims for Utility Model Registration] (1) A pump case, a curved guide path formed on the surface of the pump case to which a fluid feeding tube can be attached, and a drive disposed within the pump case. a roller holder supported by a shaft and rotated by the driving of the drive shaft;
A roller that rotates while pressing the tube held in the guide path against the tube pressure-closing support portion of the guide path by rotation of a roller holder, and is capable of sequentially forcing the fluid in the tube from the upstream side to the downstream side. In the roller pump, a lower holding plate is disposed below the tube attachment area of the curved guide path and has a surface that comes into contact with the tube as a slippery surface, and is supported by the roller holder; , a roller pump characterized in that the roller holder supports an upper holding plate which is disposed above the tube attachment area of the curved guide path and whose surface that comes into contact with the tube is a slippery surface; . (2) The roller pump according to claim 1, wherein each of the slippery surfaces of the lower holding plate and the upper holding plate is made of tetrafluoroethylene. (3) The roller pump according to claim 1, wherein the lower holding plate is formed of a ring-shaped member supported by a roller holder. (4) The roller pump according to claim 1, wherein the roller holder is provided with a notch for inserting and attaching the tube to the guide path. (5) The roller pump according to claim 4, wherein the cutout is formed on the upper holding plate.
