特徴とする曲げ戻し用縦ローラの支持構造。[Claim for Utility Model Registration] An unbending device that rotatably supports a vertical unbending roller that contacts the inner surface of the left and right flanges of a previously deeply bent groove-shaped cross section to unbend these flange portions. The support structure for the vertical rollers includes a pair of left and right vertical rollers, each of which has a vertical axis integrally provided above the vertical roller for unbending, and is movable and adjustable symmetrically in the width direction of the formed material. Each of the movable blocks is integrally provided with a plurality of shaft receiving portions protruding toward the other side at different levels and forming a staggered pattern, and the shaft of the vertical roller for bending back can be freely rotated by a bearing attached to the shaft receiving portion. A support structure for a vertical roller for unbending, characterized in that it is supported.
