To provide an elevator door open/closed-state confirmation device in which contact failures hardly occurs.SOLUTION: An elevator door open/closed-state confirmation device confirms an elevator door open/closed state. The elevator door open/closed-state confirmation device comprises: a switching device 2 connected to an electric circuit, installed at a fixed location, and capable of switching between an on-state with the electric circuit closed and an off-state with the electric circuit opened; and a switch on/off switching mechanism 3 to switch between the on-state and off-state of the switching device 2. The switching device 2 has: a fixed terminal 20 with an installation position fixed and connected to electrically to the electric circuit; and a movable terminal 21 moving toward and away from the fixed terminal 20 while remaining facing the fixed terminal 20, closing the electric circuit by touching the fixed terminal 20, and opening the electrical circuit by moving away from the fixed terminal 20. The switch on/off switching mechanism 3 is configured to move the movable terminal 21 toward a contact/separation direction with the operation of the door opening/closing.SELECTED DRAWING: Figure 2

    【課題】接触不良が起きにくいエレベータ用のドアの開閉確認装置を提供することを課題とする。【解決手段】エレベータのドアの開閉状態を確認するエレベータ用のドアの開閉確認装置であり、電路に接続され、定位置に設置され且つ電路を閉じた入状態と開いた切状態とに切替可能なスイッチ装置2と、スイッチ装置2の入状態と切状態とを切り替える入切切替機構3とを備え、スイッチ装置2は、設置位置が固定され且つ電路に電気的に接続される固定端子20と、固定端子20に対向配置された状態のまま前記固定端子20に接離する接離方向に動き、且つ固定端子20に接触することで電路を閉じ、固定端子20から離間することで電路を開く可動端子21とを有し、入切切替機構3は、ドアの開閉動作に伴って可動端子21を接離方向で動かすように構成される。【選択図】図2
