Forming of a rough forming section in an electric resistance welded tube forming apparatus equipped with multiple pairs of forming rolls that sequentially curve form a forming material in a rough forming section, and a free roller guide arranged between each pair of step forming rolls. In a roll device, the lower roll of a plurality of pairs of forming rolls that is rotationally driven has a concave outer periphery having a roll width that is approximately the same as the roll width of the upper roll perpendicular to the lower roll and that allows the backing portion of the forming material to protrude to both sides. It is characterized in that it is formed into a curved short roll shape, and the rollers on both sides of each free roller guide located at the front stage in the forming direction of each step forming roll pair are formed into a roller shape that holds the buckling part of the forming material. A forming roll device for the rough forming section of an ERW tube forming device.
