A center roller that is rotatably supported on a base unit and defines the radius of curvature of the tubular body, and a center roller that is located on the base unit and between the center roller and the tubular body. In the tubular body bending device, the tubular body bending device includes a revolving roller that revolves around the center roller while sandwiching the center roller, and a driving means that is installed at an appropriate position of the base unit and operates to revolve the revolving roller. A concave groove having a radius of curvature approximately equal to the outer diameter of the tubular body is formed on the outer peripheral surface of the revolving roller, and a part of the outer periphery is formed in at least one of the center roller and the revolving roller in the axial direction. 1. A tubular body bending device, characterized in that a notched string portion is formed by cutting out a tube. 2. The tubular body bending device according to claim 1, further comprising a speed variable means for changing the revolution speed of the revolution roller by the drive means. 3. The tubular body bending device according to claim 1 or 2, further comprising a support frame for rotatably supporting the base unit and positioning means for positioning the base unit at a predetermined rotational position.
