To prevent looseness of a bolt of a friction damper.SOLUTION: A friction damper 10 comprises a lower movable plate 11, a friction plate 12, a slide plate 13, and a middle movable plate 14 stacked in order, and a fastening body 20 for fastening the middle movable plate 14, the friction plate 12, the slide plate 13, and an upper movable plate 17. The friction plate 12 is fixed to the lower movable plate 11. The slide plate 13 is fixed to the movable plate 14. The friction plate 12 and the slide plate 13 can slide on each other. Bolt holes 12a and 11a are formed in the friction plate 12 and the lower movable plate 11. Long holes 13a and 14a are formed in the slide plate 13 and the movable plate 14. The fastening body 20 comprises a bolt 21 inserted into the long holes 13a and 14a and the bolt holes 11a and 12a, a nut 22 screwed to the bolt 21, and a pipe 28 into which the bolt 21 is inserted, and housed in the long holes 13a and 14a and the bolt holes 11a and 12a. The pipe 28 prevents rotation of the bolt 21 when the bolt 21 moves in a longitudinal direction of the long holes 13a and 14a.SELECTED DRAWING: Figure 3
【課題】摩擦ダンパーのボルトの緩みを防止する。【解決手段】摩擦ダンパー１０は、順に重ねられた下部可動板１１、摩擦板１２、滑り板１３及び中部可動板１４と、中部可動板１４、摩擦板１２、滑り板１３及び上部可動板１７を締め付ける締結体２０と、を備え、摩擦板１２が下部可動板１１に固定され、滑り板１３が可動板１４に固定され、摩擦板１２と滑り板１３が相互に摺動可能であり、摩擦板１２及び下部可動板１１にボルト孔１２ａ，１１ａが形成され、滑り板１３及び可動板１４に長孔１３ａ，１４ａが形成され、締結体２０が、長孔１３ａ，１４ａ及びボルト孔１１ａ，１２ａに挿通されたボルト２１と、ボルト２１に螺合したナット２２と、ボルト２１が通され、長孔１３ａ，１４ａ及びボルト孔１１ａ，１２ａに収容されたパイプ２８と、を有し、パイプ２８は、ボルト２１が長孔１３ａ，１４ａの長手方向に移動する際のボルト２１の回転を防止する。【選択図】図３
