To provide a door opening/closing device of an elevator capable of suppressing occurrence of a gap between a door pocket and a door and between doors even when an opening/closing mechanism for opening/closing the doors fails.SOLUTION: A door opening/closing device for an elevator includes a door pocket 13 provided on the side of a car doorway, a first door 3 capable of being stored in the door pocket 13 when the door is opened, a second door 4 disposed closer to the door pocket side than the first door to be stored in the door pocket 13 when the door is opened, and a door opening/closing mechanism for performing opening/closing movement by linking the first door 3 and the second door 4. The door opening/closing device includes a first movement regulation mechanism regulating the movement in the opening/closing direction in which the first door 3 and the second door 4 are separated from each other in a state where a second door side end part of the first door 3 and a first door side end part of the second door 4 are overlapped with each other in a car doorway direction during a closed state of the doors, and a second movement regulation mechanism regulating the movement in the door closing direction of the second door 4 in a state where the second door side end part of the door pocket 13 and a door pocket side end part of the second door 4 are overlapped with each other in the car doorway direction.SELECTED DRAWING: Figure 4
【課題】ドアを開閉する開閉機構が故障しても、戸袋とドアの間及びドア同士間に隙間が発生することを抑制することができるエレベータのドア開閉装置を提供する。【解決手段】かご出入口の側方に設けられる戸袋13と、戸開時に戸袋13に収納可能な第1のドア3と、第1のドアよりも戸袋側に配置され戸開時に戸袋13に収納可能な第2のドア4と、第1のドア3と第2のドア4を連動して開閉動作させるドア開閉機構と、を備え、戸閉状態において、第1のドア3の第2のドア側端部と第2のドア4の第1のドア側端部とがかご出入口方向で重なる状態での第1のドア3及び第2のドア4の互いに離間する開閉方向の移動を規制する第1の移動規制機構と、戸袋13の第2のドア側端部と第2のドア4の戸袋側端部とがかご出入口方向で重なる状態での第2のドア4の戸閉方向の移動を規制する第2の移動規制機構と、を備えている。【選択図】図4
