Claims

[Scope of utility model registration request]

In a tube-type roller pump that sucks in and discharges liquid by giving a pumping action to an elastic pumping tube along the arcuate inner circumferential surface of a pump case through the pressing and rolling action of rollers and the restoring action of the pumping tube. , the pumping tube has a first tube located on the axis in the pressing direction.
The inner diameter of the second bulging part located on the axis perpendicular to the pressing direction is formed larger than the inner diameter of the bulging part, and the roller has a recess on the outer periphery that accommodates the pumping tube in a pressed state. , a curved bulge pressing the first bulge is formed in the center of the recess, and relief grooves facing the second bulge are formed on both sides of the curved bulge. Tube type roller pump.
