PROBLEM TO BE SOLVED: To improve an attenuation property while reducing attenuation device setting quantity.SOLUTION: An attenuation device 80 comprises a first arm 92, a second arm 94 and a damper 100. The first arm 92 has one end part 92M that is rotatably connected to a lower frame 82 set on a bottom 13 of a lower structure 12. The second arm 94 has an end part 94A that is rotatably connected to an upper frame 84 set on an undersurface 15 of an upper structure 14. The other end part 92N of the first arm 92 and the other end part 94N of the second arm 94 are rotatably connected through a connection member 96. A connection part 105 of a holder 104 of the damper 100 is rotatably connected to an upper frame 86 set on the undersurface 15 of the upper structure 14. A connection part 101 of a shaft 102 is rotatably connected to the connection member 96 that rotatably connects the other end part 92N of the first arm 92 and the other end part 94N of the second arm 94.SELECTED DRAWING: Figure 2 【課題】減衰装置の設置数を抑えつつ、減衰性能を向上させる。【解決手段】減衰装置８０は、第一アーム９２、第二アーム９４、及びダンパー１００と有している。第一アーム９２は一端部９２Ｍが下部構造部１２の底部１３に設けられた下側架台８２に回転自在に連結され、第二アーム９４は一端部９４Ａが上部構造部１４の下面部１５に設けられた上側架台８４に回転自在に連結されている。第一アーム９２の他端部９２Ｎと第二アーム９４の他端部９４Ｎとは、連結部材９６によって回転自在に連結されている。ダンパー１００のホルダー１０４の連結部１０５が上部構造部１４の下面部１５に設けられた上側架台８６に回転自在に連結されると共に、シャフト１０２の連結部１０１が第一アーム９２の他端部９２Ｎと第二アーム９４の他端部９４Ｎとを回転自在に連結している連結部材９６に回転自在に連結されている。【選択図】図２
