PROBLEM TO BE SOLVED: To provide a cage movement inhibitor which can prevent travel of a cage with an opened door with a simple constitution.SOLUTION: A cage movement inhibitor 50 of an elevator comprises: a pair of drive roller holding components 52a, 52b which are fixed on a landing-side surface of a cage door of a cage 12 along a vertical direction in the state that the components are separated from each other by a specified clearance, and transmit opening/closing operation of cage doors 14a, 14b to landing doors 5a, 5b; and a door opening travel prevention plate 74 which is located above the landing door 5a on a hoistway side of an elevator landing site, and is so installed that an end edge part 74a thereof is positioned at a position overlapping on the drive roller holding components 52a, 52b in a vertical direction when the cage door 14a is in an open state. The plate 74 is provided with a landing side notch 76 so as not to interfere with the drive roller holding components 52a, 52b. Each of the drive roller holding components 52a, 52b is provided with a cage side notch 56 with which the end edge part 74a of the plate 74 is brought into contact when the cage door 14a is so operated as to be opened.SELECTED DRAWING: Figure 1
【課題】簡易な構成でかごの戸開走行を防止できるかご移動制止装置を提供する。【解決手段】エレベータのかご移動制止装置50はかご12のかご扉の乗場側表面に所定間隔を空けた状態で鉛直方向に沿って固定され、かご扉14a,14bの開閉動作を乗場扉5a,5bに伝達する一対のドライブローラつかみ部材52a,52bと、エレベータ乗場の昇降路側において乗場扉5aの上方に配置され、かご扉14aが開状態にあるときにドライブローラつかみ部材52a,52bと鉛直方向で重なる位置に端縁部74aが位置するように設置された戸開走行防止用プレート74とを備える。このプレート74には、ドライブローラつかみ部材52a,52bに干渉しないようにする乗場側切欠部76が形成される。ドライブローラつかみ部材52a,52bには、かご扉14aが開動作したときにプレート74の端縁部74aが係合するかご側切欠部56が形成されている。【選択図】図1
