To provide a door device of an elevator capable of securing enough airtightness between a car door and a sill member.SOLUTION: A door device of an elevator comprises a car door, a sill member for guiding the car door to an opening and closing direction at a lower end of a doorway, and a blocking member capable of moving in a vertical direction between a blocking position for blocking between the car door and the sill member and a retracted position equal to or lower than an upper end of the sill member. The car door has a pulling-up part for pulling up the blocking member toward the blocking position by that the car door moves in a door closing direction in a state in contact with the blocking member. The pulling-up part pulls up the blocking member to the blocking position by that the car door contacts with the blocking member in the retracted position by moving toward the door closing direction and the car door moves to a fully closed position. The blocking member has a size capable of blocking between the car door and the sill member and brings an upper end thereof into close contact with a lower end part of the car door by being pulled up to the fully closed position by the pulling-up part.SELECTED DRAWING: Figure 3
【課題】かごドアと敷居部材との間において十分な気密性を確保できるエレベータのドア装置を提供することを課題とする。【解決手段】本発明は、かごドアと、出入口の下端においてかごドアを開閉方向に案内する敷居部材と、かごドアと敷居部材との間を塞ぐ閉塞位置と敷居部材の上端以下の退避位置との間で上下動可能な閉塞部材と、を備え、かごドアは、閉塞部材と接触した状態でかごドアが戸閉方向に移動することで該閉塞部材を閉塞位置に向けて引き上げる引き上げ部を有し、引き上げ部は、かごドアが戸閉方向に向けて移動することで退避位置にある閉塞部材と接触し、全閉位置まで移動することで閉塞部材を閉塞位置まで引き上げ、閉塞部材は、かごドアと敷居部材との間を塞ぐことができる寸法を有し、引き上げ部によって全閉位置に引き上げられることでその上端をかごドアの下端部に密接させることを特徴とする。【選択図】図3
