The passenger conveyor device 1 of the first embodiment is provided with a buffer portion 17 that buffers a collision force between the terminal end portion 2A of the lower entrance / exit 2 and the civil engineering structure 10 of the lower floor F ₁ . The buffer portion 17 is configured by extending a lower entrance / exit (an entrance / exit on one side) 2 to an upper surface of the civil engineering structure 10 approaching the lower entrance / exit 2. Further, a space (clearance) M ₁ is provided between the lower edge 7c of the main body frame 7 and the peripheral wall 11B of the structure on the lower floor, which is set in consideration of the interlayer displacement angle generated by the large earthquake motion. In addition, the boarding / alighting floor 18 having a plate thickness t and forming a part of the lower boarding / alighting entrance 2 that is fixed and extended on the side opposite to the main body frame 7 side from the terminal end 2A
It is formed by adding receiving members 19 and 20 which serve as a reinforcing member for this. Here, the space M ₁ is defined by the surrounding wall 1 when the body frame 7 moves in the longitudinal direction in which the space M ₁ is reduced as indicated by the arrow Q.

The receiving members 19 and 20 and the civil structure 10
A space M ₂ (relationship of M ₁ ≈M ₂ ) and a space M corresponding to the space M 2 are formed between and, and the boarding / alighting floor 18 and the civil structure 10 have an overlap margin M ₃ (M ₁ <M ₃ Relationship) with the body frame 7
Is moved to the side opposite to the arrow Q by an amount corresponding to the allowable movement value M ₁ , the space M is exposed by the overlap margin M ₃ , and the passerby is set not to drop there.

Here, in the latter installation form of the above-mentioned conventional example, both end portions in the longitudinal direction thereof are supported by the building or civil engineering structure, and the bottom part around the center of the length of the inclined portion is also the building structure. Although the three-point distributed support method is used to support (a shape similar to that is shown in the imaginary line Y in FIG. 1), in the first embodiment, the total length L of the main body frame 7 is reduced by L ₂ , and the support point spacing is reduced. Since L ₃ is greatly reduced and the upper side and the lower side are roughly supported in two places, the installation work cost will be lower than before, but the space utilization effect by omitting the above Y part (Y part It can be used as a storeroom, a shop, or a passageway. In addition, getting on and off 1
