Claim 0:
1. A vibration suppression device for a rope-like body of an elevator, comprising:
a first unit which is capable of movement in a direction in which a distance from an equilibrium position of vibration of the rope-like body of the elevator changes; and
a first stopper, fixed in position and shape, which stops movement of the first unit to a position closer than a first distance from the equilibrium position,
wherein the first unit includes
a first displacement amplifier which is arranged to be directed to a first position in a longitudinal direction of the rope-like body and amplifies displacement of vibration of the rope-like body by an attractive force which becomes stronger as the rope-like body approaches closer, and
a first restriction body which inhibits the rope-like body from approaching the first displacement amplifier closer than a predetermined distance, and
wherein
the first unit moves together with the rope-like body towards a direction separating from the equilibrium position when the rope-like body, which is moving towards the direction separating from the equilibrium position, contact with the first unit, and
the first stopper restricts the movement of the first unit to a position closer than the first distance from the equilibrium position when the first unit, which is moving towards a direction approaching the equilibrium position in a process where the rope-like body returns to the equilibrium position, contact with the first stopper.
