<P>PROBLEM TO BE SOLVED: To provide a roller correction machine for an H-section steel having a simple configuration, eliminating complicate control during correction, being excellent in replacement of rollers, and enabling simultaneous reduction of a web and a flange. Ž<P>SOLUTION: The roller correction machine 10 for the H-section steel has a pair of web correction rollers 16 for pressing both sides of the web 13 of the H-section steel 12 which are externally mounted on a main shaft 11 installed connectedly with a drive device and enabling free reduction and rotation. The roller correction machine for the H-section steel includes ring members 17 which are respectively externally mounted on both outer sides of the pair of the web correction rollers 16 of the main shaft 11 and are enabled to be eccentric to the axial center of the main shaft 11, a flange reduction correction roller 20 which is mounted on an outer circumferential surface of a ring member 17 through a bearing 18 and comes into contact with the leading end of the flange 19 while making the ring member 17 eccentric by following the variation of the leading end position of the flange 19 of the H-section steel 12, and an energizing means 22 being mounted on the main shaft 11, pressing the flange reduction correction roller 20 to the leading end surface of the flange 19, and returning the axial center of the ring member 17 toward the axial center of the main shaft 11.
