PROBLEM TO BE SOLVED: To reliably perform winding of a rolled material in such a case that the plate width or plate thickness of the rolled material is changed.SOLUTION: A rolled material tension adjusting device comprises: arms which are fixed to a rotating shaft, which assume a symmetrical shape centering on the rotating shaft, and which make oscillating movement centering on the rotating shaft; and a pair of dancer rolls which assume the same shape, which are arranged at free ends in symmetrical positions of the arms centering on the rotating shaft, respectively, and over which a rolled material is looped in an S-shape or an inverted S-shape. The pair of dancer rolls is set at an arbitrary angle of 0-180 degrees in accordance with a rolled material tension set value, and a rotary driving force of another driving machine is set.SELECTED DRAWING: Figure 5 【課題】圧延材の板幅あるいは板厚が変えられるような場合にあって、圧延材の巻き取りを確実に行えるようにする。【解決手段】回転軸に固定され、該回転軸を中心にして対称形状をなして該回転軸を中心として揺動運動するアームおよび同一形状をなして、前記回転軸を中心として前記アームの対称位置にあるそれぞれの自由端部に配設され、圧延材がＳ字状もしくは逆Ｓ字状に巻き掛けられる一対のダンサーロールを備え、一対のダンサーロールが、圧延材張力設定値に対応して０度から１８０度の範囲に任意の角度に設定され、前記他の駆動機の回転駆動力が設定される。【選択図】図５
