DAMPING DEVICE AND PASSENGER CONVEYOR

PROBLEM TO BE SOLVED: To provide a damping device of a skeleton structure and a passenger conveyor using the same, capable of miniaturizing and lightening a brace by preventing application of moment to the brace in increasing a deformation amount of the brace and transferring the same to an attenuation element, in the damping device of the skeleton structure in which bending deformation occurs.SOLUTION: In a damping device of a skeleton structure in which bending deformation occurs, an attenuation element deformed by a rotating member in increasing a deformation amount of a brace and transferring the same to the attenuation element, is disposed on a first intersecting portion as an intersecting portion of one of an upper chord material and a lower chord material, and a connecting member. As connection with other members, of a first rod member and a second rod member corresponding to the brace, are implemented only by rotational support at both ends, moment does not act on the first rod member and the second rod member, thus these members can be miniaturized and lightened. 【課題】曲げ変形が生じる骨組構造物の制振装置において、ブレースの変形量を拡大して減衰要素に伝える際に、ブレースにモーメントを作用させないことで、ブレースの小型軽量化が可能な骨組構造物の制振装置とそれを用いた乗客コンベアを提供する。【解決手段】曲げ変形が生じる骨組構造物の制振装置において、ブレースの変形量を拡大して減衰要素に伝える際に、回転部材によって変形させられる減衰要素を、上弦材と下弦材とのうちの一方と接続部材との交差部である第一交差部に配置することで、ブレースに相当する第一棒部材、第二棒部材とも他部材との接続は両端における回転支持だけなので、第一棒部材、第二棒部材にはモーメントが作用せず、これらの部材の小型軽量化が可能となる。【選択図】 図１
