ABSTRACT:
In an elevator door apparatus, landing fire protection members having engaging portions extending in a direction parallel to an opening and closing direction of landing doors are fixed at door recess portions of an entrance. Further, door side fire prevention plates extending in a direction perpendicular to the opening and closing direction of the landing doors are fixed to side end portions of the landing doors. Insert holes in which the engaging portions are inserted when the doors are closed are provided in the door side fire prevention plates. When a fire occurs, the engaging portions are brought into contact with the side edge portions of the insert holes, which restricts warping of the landing doors.
