PROBLEM TO BE SOLVED: To provide a rope vibration suppressing unit that is configured so that the whole length of an anti-vibration bar can be shortened as much as possible.SOLUTION: An anti-vibration bar 102 is turned by an actuator 108 to be switched between a standby state where the bar stands and an operation state where the bar lies down beside a target rope part 24A as an anti-vibration target. A backup member 116 is turned by the actuator 120 to be switched between a standby state where an arm part 116A stands and an operation state where a support part 116B provided at a tip of the arm part 116A enters a side position at the side opposing to the target rope part 24A in the operation state, of a tip part of the anti-vibration bar 102, which allows the support part 116B to receive and support the tip part which is displaced in a horizontal direction by collision of the target rope part 24A laterally vibrated, in the operation state.SELECTED DRAWING: Figure 4 【課題】振れ止めバーの全長を可能な限り短縮できるロープ振れ抑制ユニットを提供する。【解決手段】振れ止めバー１０２が、アクチュエータ１０８で回動されて、起立した待機状態と振れ止め対象となる対象ロープ部分２４Ａの側方に横たわる作動状態とに切り換えられ、バックアップ部材１１６が、アクチュエータ１２０で回動されて、アーム部１１６Ａが起立した待機姿勢と、アーム部１１６Ａの先端に設けられた支持部１１６Ｂが振れ止めバー１０２の先端部の、作動状態における前記対象ロープ部分２４Ａとは反対側の側方位置まで進出した状態となる作動姿勢とに切り換えられ、前記作動姿勢において、横振れする対象ロープ部分２４Ａの衝突によって水平方向に変位しようとする前記先端部を支持部１１６Ｂで受け止めて支持する構成とした。【選択図】図４
