PROBLEM TO BE SOLVED: To solve a problem that width dimension of a rail groove guiding a shutter cannot be controlled when an elevator landing doorway device is installed in a landing because a vertical frame is integrally assembled by welding in a jamb of the conventional elevator landing doorway device in which the fireproof shutter is incorporated. SOLUTION: This elevator landing doorway device has a structure that a landing side front board 4a and a car side front board 4b are divided in the front and rear of a rail groove 12 and is constituted by fixing all the device with screws without welding. Thereby, the width dimension of the rail groove can be controlled into predetermined dimension by a stud bolt 13 and a nut 14, so that a fireproof shutter can be smoothly lifted.
