Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the accuracy of a clearance between a stiffening pipe inner surface and a yield strength reduction part of a brace.SOLUTION: This damper has: a steel brace material that is provided with a yield strength reduction part of an H-shaped section having a tensile strength and a compressive strength smaller than those of both ends in an axial intermediate part; a stiffening pipe that surrounds the brace material; and a stiffening member that is placed over the yield strength reduction part so as to cover the flange surface and the flange side surface of the yield strength reduction part, and forms a prescribed clearance between the yield strength reduction part and the inner surface of the stiffening pipe.SELECTED DRAWING: Figure 1 【課題】補剛管内面とブレースの耐力低減部との間のクリアランスの精度を向上させる。【解決手段】両端部に比べて引張耐力及び圧縮耐力が小さいＨ形断面の耐力低減部を軸方向中間部に備えた鋼製のブレース材と、前記ブレース材を取り囲む補剛管と、前記耐力低減部のフランジ面及びフランジ側面を覆うように前記耐力低減部に被せられ、前記耐力低減部と前記補剛管の内面との間に所定のクリアランスを形成する補剛部材と、を有するダンパー。【選択図】図１
