Abstract
In a tube type roller pump having a stator, an elastic tube to which two tube connectors are fixed at a predetermined interval, and a drawing roller, movement of the tube connectors is regulated by a regulating portion disposed on a main body that constitutes the stator. The tube type roller pump prevents separation and expansion of the elastic tube from the stator, and thus is small in discharge error.
