PROBLEM TO BE SOLVED: To provide an elevator emergency stop device that enables a wedge to be light in weight.SOLUTION: This elevator emergency stop device is provided with: a pair of wedges that are provided to a lifting body, arranged to face each other with a guide rail therebetween, and raised so as to advance toward the guide rail when the descending speed of the lifting device exceeds a rated speed; brake shoes that are fitted to the wedges; and a plurality of transfer rollers that rotatably come into contact with the wedges from the side opposed to the brake shoes. Each wedge is provided with an iron wedge body to which the brake shoe is fitted, and a roller reception part that has a pressure reception surface for receiving a pressing force from each transfer roller and that is fitted to the wedge body, and the roller reception part is made of a material lighter than that of the wedge body.SELECTED DRAWING: Figure 6

    【課題】楔を軽量化することができるエレベータの非常止め装置を得ることにある。【解決手段】エレベータの非常止め装置は、昇降体に設けられ、ガイドレールを間に挟んで向かい合うとともに、昇降体の下降速度が定格速度を超過した時にガイドレールに向けて進出するように引き上げられる一対の楔と、楔に取り付けられたブレーキシューと、ブレーキシューとは反対側から楔に回転自在に接触する複数の転送ローラと、を備えている。各楔は、ブレーキシューが取り付けられた鉄製の楔本体と、楔本体に取り付けられ、転送ローラから押圧力を受ける受圧面を有するローラ受け部と、を備え、ローラ受け部が楔本体よりも軽量な材料で形成されている。【選択図】図6
