To provide a bending device for a rod-like member which can flexibly deal with various rod diameters and bending inner diameters of a bent portion.
The device is used to bend the rod-like member (B) by rotating an arm (30) around its rotation center to press the rod-like member (B) such as a reinforcing steel by a roller (40) supported by the arm so as to follow collars (50) having a curved surface. In the device, a distance from the rotation center of the arm (30) to the roller (40) is made variable, and, in addition, two or more different sizes of collars (50) are prepared. By changing a combination of the distance and the sizes of the collars, it is possible to deal with various rod diameters and bending inner diameters of the bent portion.
