To provide an elevator landing door lock device that can suitably prevent a door closed detection unit, which detects that the hall door is in a fully closed state, from malfunctioning due to foreign objects such as dust.SOLUTION: A landing door lock device 4 includes, as components on the landing entrance side, a locked portion 60a and a switch 61 of a door closing detection unit, and, as components on the landing door side, a locking member 42 that engages with the locked portion 60a and an operation piece 58 for a terminal of the switch 61. The switch 61 is provided so that the terminal is aligned along a plane that intersects with the closing operation direction of the landing door, and the operation piece 58 is provided so as to come into contact with and act on the terminal of the switch 61 by translational motion associated with the closing operation of the landing door. This makes it difficult for foreign objects such as dust to accumulate on the terminal of the switch 61, preventing malfunction of the door closing detection unit.SELECTED DRAWING: Figure 5
【課題】乗場ドアが全閉した状態にあることを検出するドア閉検出部が塵埃等の異物を原因として動作不良を引き起こすことを好適に防止することができるエレベータの乗場ドアロック装置を提供する。【解決手段】乗場ドアロック装置4は、乗場出入口側の構成として、被ロック部60aと、ドア閉検出部のスイッチ61とを備え、乗場ドア側の構成として、被ロック部60aと係合するロック部材42と、スイッチ61の端子に対する操作片58とを備える。スイッチ61は、端子が乗場ドアの閉動作方向と交差する面に沿うように設けられ、操作片58は、乗場ドアの閉動作に伴う並進運動によりスイッチ61の端子に接触して作用するように設けられる。これにより、スイッチ61の端子に塵埃等の異物が堆積しにくくなり、ドア閉検出部の動作不良が防止される。【選択図】図5
