Patent number: 11958720Abstract: 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 (20) includes a movable unit and a stopper. The movable unit can move in a direction in which a distance from an equilibrium position (19) of the rope-like body changes. The stopper restricts movement of the movable unit to a position closer than a first distance (d1) from the equilibrium position (19). The movable unit includes a displacement amplifier and a restriction member. The displacement amplifier is arranged to be directed to a first position (P1) 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.Type: GrantFiled: November 6, 2019Date of Patent: April 16, 2024Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Tomohiro Asamura, Eiichi Saito, Seiji Watanabe
