By having such a configuration, it is possible to prevent an accident in which the movable side wall plate 27 is curved inward of the boarding passage 7 and contacts a passenger during an earthquake.

  FIG. 9 shows a state in which a lateral displacement has occurred in the getting-on / off passage 7 due to the shaking of the earthquake. In FIG. 9, the movable side wall plate 27 is elastically deformed following the building side entrance / exit three-way frame 19 and the hoistway side entrance / exit three-way frame 16 whose lateral positions are shifted. At this time, the building side end and the hoistway side end of the movable side wall plate 27 rotate around the shafts 29 and 31 in accordance with the deformation of the movable side wall plate 27. Even when the lateral displacement and expansion / contraction occur simultaneously in the boarding / exiting passage 7, as described above, it is possible to easily follow the displacement of the building side entrance / exit three-way frame 19 and the hoistway side entrance / exit three-way frame 16.

  According to the first embodiment of the present invention, even when the entrance / exit passage 7 is deformed due to an earthquake, the movable side wall plate 27 follows the movement of the building side entrance / exit three-side frame 19 and the hoistway side entrance / exit three-side frame 16, The curved portion can absorb displacement in any direction. Moreover, since the building side end part and the hoistway side end part of the movable side wall plate 27 are rotatably provided via the shafts 29 and 31 on the building side vertical frame 19a and the hoistway side vertical frame 16a, the entrance / exit passage 7 There is no fear that an excessive load will act on the movable side wall plate 27 even during the deformation of.

  Further, unlike a conventional landing device in which a plurality of flat movable side wall plates are connected by an expansion / contraction sliding mechanism, each side wall surface of the getting-on / off passage 7 is between the building-side entrance / exit three-way frame 19 and the hoistway-side entrance / exit three-side frame 16. Since the movable side wall plate 27 is composed of a single movable side wall plate 27, the structure is simple, and it is possible to provide it inexpensively without requiring time for production and installation. Moreover, since the telescopic sliding mechanism is not provided unlike the conventional hall device, maintenance work after installation is not required.

  In addition, the movable side wall board 27 in Embodiment 1 is comprised by the stainless steel plate of about 0.6-3.2 mm (more preferably about 1.6-2.3 mm), for example, and a building body side edge part and The hoistway side end can be easily bent, and can be provided with a predetermined strength and elasticity, which is practical.
