    摘要： A tube pump comprises a rotor configured to have a roller and to hold the roller to be able to make an orbital motion along the inner circumferential surface of the cap. The rotor includes a disk part which holds the roller on a base side, and a tube press member that engages with the disk part so that the tube does not move to the base side with respect to the disk part, seals a gap formed with respect to the inner circumferential surface of the cap, and is capable of rotating along an outer circumferential part of the disk part is provided at the outer circumferential part of the disk part.
