Abstract (en)
Tube pump capable of suppressing torque variation in a drive motor regardless of the rotation direction of a rotor unit and manufacturing easily and cheaply. The tube pump (1) includes a casing (2) which a liquid-flowing tube (3) is arranged; a drive motor (4) provided with a driving shaft (4a) rotatable in forward and reverse directions; a rotor body (20); roller holders (40) supported on the rotor body (20) to swing with respect to the rotor body (20); pressing rollers (50) rotatably supported on the roller holders (40) to press the tube (3) against an inner circumferential wall surface (2a) of the casing (2); and biasing units (60) biasing the roller holders (40), when swung, to be returned to a pre-swing position. The roller holders (40) are configured to swing with respect to the rotor body (20) in a direction opposite to a rotation direction of the rotor body (20).
