To effectively prevent the vibration of a main rope connected to an elevator car and the counterweight with causing little noise, which can also be applied to an elevator without a machine.SOLUTION: There is provided a swing prevention device for a main rope of an elevator which bridges over a hoist machine to suppress the vibration of the main rope that connects the car and the counterweight, comprising a car side swing prevention device that is suspended by a support pulley on the car side placed above the car and has a guide hole through which the main rope on the car side is inserted, a counterweight side swing prevention device suspended by a support pulley on the counterweight side arranged above the counterweight and has a guide hole through which the main rope on the counterweight side is inserted, and a rope for the swing prevention device that is wound over the support pulley on the car side, the support pulley on the counterweight side, and the hoisting machine to suspend the car side swing prevention device and the counterweight side swing prevention device. The swing prevention device raises and lowers the car side swing prevention device and the counterweight side swing prevention device in conjunction with the raising and lowering of the car and the counterweight.SELECTED DRAWING: Figure 1
【課題】エレベータのかご及び釣合い重りに連結された主索の振動を効果的に防止でき、騒音が少なく、機械室のないエレベータにも適用可能とする。【解決手段】巻上機にかけ渡されるとともに、かごと釣合い重りとを連結する主索の振れを抑制するエレベータの主索振れ止め装置であって、かごの上方に配置されたかご側の支持滑車によって懸架され、かご側の主索が挿通される案内孔を有するかご側振れ止め装置と、釣合い重りの上方に配置された釣合い重り側の支持滑車によって懸架され、釣合い重り側の主索が挿通される案内孔を有する釣合い重り側振れ止め装置と、かご側の支持滑車、釣合い重り側の支持滑車及び巻上機にかけ渡され、かご側振れ止め装置及び釣合い重り側振れ止め装置を懸吊する振れ止め装置用のロープとを備え、かご及び前記釣合い重りの昇降に連動してかご側振れ止め装置及び釣合い重り側振れ止め装置を昇降させる。【選択図】図1
