Abstract
There is provided a vibration suppression device for a rope-like body of an elevator that can inhibit displacement of the rope-like body from becoming unstable due to amplification of the displacement and can make a movable range of the rope-like body wider. A vibration suppression device () includes a movable unit and a stopper. The movable unit can move in a direction in which a distance from an equilibrium position () of the rope-like body changes. The stopper restricts movement of the movable unit to a position closer than a first distance (d) from the equilibrium position (). The movable unit includes a displacement amplifier and a restriction member. The displacement amplifier is arranged to be directed to a first position (P) of the rope-like body. The displacement amplifier amplifies displacement of the rope-like body. The restriction member inhibits the rope-like body from approaching the displacement amplifier.
