PROBLEM TO BE SOLVED: To solve the problems of a conventional rotor for a tube pump that a spring mechanism for buffering the rotor from pulse or load corresponds only to one rotating direction and using the rotor in the reverse rotating direction is limited to cases in which generation of large pulse is allowed, long time operation is difficult because of low effects of buffering the load, and enhancing strength of a housing, a motor, etc., allows the long time operation as well as causes cost rise. SOLUTION: A rotor for a tube pump is composed of a rotation rotor, a plurality of first swing parts with their base parts rotatably/pivotally supported by the rotation rotor, an arm-like second swing part with its base part rotatably/pivotally supported by the respective first swing parts, rollers rotatably/pivotally supported by respective free ends of the second swing part, and buffering members abutted to the side faces of the second swing part so as to direct the respective rollers to their radially outward directions.
