PROBLEM TO BE SOLVED: To provide an elasto-plastic hysteretic damper capable of functioning as a damper with respect to input in a plurality of directions.SOLUTION: The elasto-plastic hysteretic damper applicable to a building and/or a structure comprises: a pair of first reinforcement parts 13 and 13; a plate-like shear part 11 connecting the pair of first reinforcement parts 13 and 13; and a pair of plates 14 and 15 connected between both ends of the pair of first reinforcement parts 13 and 13, respectively. The shear part 11 is tilted with respect to the first reinforcement part 13, the pair of first reinforcement parts 13 and 13 and the shear part 11 form a substantially M shape and/or substantially W shape and/or shape, and the shear part 11 performs energy absorption by being deformed when loaded by input. 【課題】複数の方向からの入力に対してダンパとして機能し得る弾塑性履歴型ダンパを提供する。【解決手段】建物及び／又は建造物に適用可能な弾塑性履歴型ダンパであって、一対の第一補強部１３，１３と、一対の第一補強部１３，１３を連結した板状の剪断部１１と、一対の第一補強部１３，１３の両端間にそれぞれ接続した一対のプレート１４，１５とを備え、剪断部１１は、第一補強部１３に対して傾斜を成し、一対の第一補強部１３，１３と剪断部１１とで略Ｍ字形及び／又は略Ｗ字形及び／又は 字形を成し、剪断部１１は、入力により荷重を受けたときに、変形してエネルギー吸収を行う。【選択図】図１
