Abstract
A tube pump that sends a fluid includes a tube, a roller, and a roller holder. In the roller holder, a guide groove is formed that receives a shaft of the roller and defines a range in which the roller is movable with respect to the roller holder. The roller holder has an inner side surface and an outer side surface as surfaces defining the guide groove in the roller holder. The inner side surface has a protrusion protruding toward the outer side surface.
