To easily straighten in a short time a bend of a web, a camber of the web and defective perpendicularly which generate in a wide flange shaped steel.

A continuous straightening device 10 is provided with a carrying mechanism 50 (50a-50f) which reverse-carries a wide flange shaped steel 60, two inversion mechanisms 40 which invert the wide flange shaped steel 60 stopped at the time of reverse-carrying and change a carrying attitude, and between the inversion mechanism 40, two pressure receiving rolls 12, 13 which are arranged facing each other in a state that the wide flange shaped steel 60 is held between the rolls and one pressurizing roll 14 freely shifted in the direction toward the rolls 12, 13 are provided. Moreover, with respect to the carrying direction of the wide flange shaped steel 60, two pressure receiving rolls 12, 13 are arranged a prescribed distance apart and the pressurizing roll 14 is arranged between two pressure receiving rolls 12, 13, and further a straightening machine 11 for the wide flange shaped steel 60, wherein roll driving mechanisms 17, 18 are provided, are combined with two pressure receiving rolls 12, 13 and provided.
