Claims

[Scope of utility model registration request]

A drive shaft rotatably provided on the main body, a plurality of pressing rollers driven by the drive shaft and arranged on a circular trajectory centered on the axis of the drive shaft, and a plurality of pressure rollers arranged on a circle concentric with the circular trajectory. a tube support having an arc-shaped guide surface disposed on the tube support, a tube held between the guide surface of the tube support and the pressing roller, and holding the tube with respect to the main body so as to be difficult to displace in the longitudinal direction of the tube. The holding means has a shaft part screwed to the main body and a head fixed to the upper part of the shaft part, and the bottom surface of the head and the top surface of the main body are connected. A roller pump comprising a bolt that clamps the tube between the two, and the bolt is screwed in by rotating in a direction in which the tube is pulled as a pressure roller is driven.
