Claims

[Claims for Utility Model Registration] 1. A pressing roller set that has a pressing roller integrated with a planetary gear that rotates planetarily around a driving gear that is rotationally driven by a driving shaft, and that is detachably interposed in the driving shaft. , consisting of a pair of pressing members that are hingedly supported by a shaft pin and pinch the pressing roller from both sides of the pressing roller set and press it by a spring force, and an elastic tube having one end communicating with the infusion is inserted between the pressing roller set and one of the pressing members. A tubing pump that injects fluid by pressing. 2. The tubing pump according to claim 1, wherein the shaft hole of at least one of the pair of pressing members hinge-supported by two shaft pins is an elongated hole extending in the direction connecting the driving shaft.
