Abstract

A peristaltic pump in which a tube is stably supported by a platen so as to be stably collapsed by fingers during normal operation, whereas, when an excessively large collapsing force is exerted by one of the fingers, the excess portion of the force is absorbed without fail so as to realize a stable pumping operation. The level or ability for absorbing the excess collapsing force is easily adjustable in accordance with changes in conditions such as the elasticity of the tube and the size of the tube. The tube can be stably set in a proper position between the platen and a group of the fingers.
