ABSTRACT:
A roller clamp is configured to maintain at a prescribed rate the flow rate of a fluid that flows through a tube. The roller clamp includes a tube winding shaft part around which a fluid flow tube is passed and which prevents the setting of the flow rate being disturbed if the tube is subject to a tensional force.
