PROBLEM TO BE SOLVED: To improve installation property and maintenance ability without forcing a construction burden to a building side.SOLUTION: An attenuator 1 is installed on an upper side of a tension sheave 109 in a posture that an axis central direction of a cylinder 11 is a vertical direction, so that a piston 12 relatively reciprocates with respect to the cylinder 11 in linkage to vertical motion of the tension sheave 109 following to lateral vibration of a governor rope G. The attenuator 1 having stroke length sufficiently longer than amplitude of reciprocation of the piston 12 is selected, and the attenuator 1 can be installed without requiring construction to a building side. Until a drop amount of the tension sheave 109 caused by rope elongation due to secular change, reaches to the stroke length of the attenuator 1, a tension state of the governor rope G can be maintained and reciprocation of the piston 12 is secured, and maintenance free to rope elongation is achieved.

    【課題】建物側への工事負担を強いることなく据付性と保守性とを改善する。【解決手段】ガバナロープGの横振れに伴うテンションシーブ109の上下動に連動してピストン12がシリンダ11に対し相対的に往復動するように、減衰器1をシリンダ11の軸心方向が上下方向となる姿勢でテンションシーブ109の上側に設置する。ピストン12の往復動の振幅よりも十分に長いストローク長を有する減衰器1の選定し、これを建物側への施工を要することなく設置することが可能となる。経年変化によるロープ伸びに起因するテンションシーブ109の下降量が減衰器1のストローク長に達するまでの間、ガバナロープGの緊張状態を保持したままピストン12の往復動が保障され、ロープ伸びに対するメンテナンスフリーが実現される。【選択図】図2
