To obtain a flooding control device for an elevator hoistway that can more reliably control water flowing into the boarding area from entering the hoistway.SOLUTION: A flooding control device for an elevator hoistway has a door threshold gap closure device 8 that has a water-absorbing and expanding function and that closes a door threshold gap 7, which is the gap between a passenger door 3 and a passenger threshold 6, by absorbing water and expanding. The door threshold gap closure device 8 has a door-side blocking member 801 provided on the passenger door 3. The door-side blocking member 801 includes a door-side expansion part 803 having a water-absorbing expansion function. As the door-side expansion part 803 absorbs water and expands, the door-side blocking member 801 comes into contact with the passenger threshold 6 and closes the door threshold gap 7.SELECTED DRAWING: Figure 2
【課題】乗場に流れ込んだ水が昇降路に浸入することをより確実に抑制することができるエレベーターの昇降路内浸水抑制装置を得る。【解決手段】このエレベーターの昇降路内浸水抑制装置は、吸水することによって膨張する機能である吸水膨張機能を有し、吸水して膨張することによって、乗場扉3と乗場敷居6との間の隙間である扉敷居隙間7を塞ぐ扉敷居隙間閉塞装置8を備え、扉敷居隙間閉塞装置8は、乗場扉3に設けられた扉側閉塞部材801を有し、扉側閉塞部材801は、吸水膨張機能を有する扉側膨張部803を含み、扉側膨張部803が吸水して膨張することによって、扉側閉塞部材801が乗場敷居6に接触して扉敷居隙間7を塞ぐ。【選択図】図2
