Abstract

The present invention concerns an elevator hoistway door structure which prevents separation of a hoistway door, wherein shoes (100) are respectively installed in right and left doors (LD,RD) and sills (200) guiding the shoe (100) are prepared. In the bottoms of the right and left doors, the primary and secondary brackets (21, 22) are coupled in such a manner that the closed state can be maintained. The primary bracket (21) and secondary bracket (22) are respectively installed at the bottom of the left door (LD) and right door (RD). Furthermore, one side of the primary bracket with a long groove (210) is “凹”-shaped and one side of the second bracket with a protrusion (220) coupled with the long groove (210) is “凸”-shaped.
