PROBLEM TO BE SOLVED: To provide a passenger conveyor device configured so as to prevent a receiving beam of a building construction and a main body frame thereof from being damaged and prevent the main body frame from falling from the receiving beam of the building construction by a large shake at a large-scale earthquake time.SOLUTION: Lengths of one and other supporting angles 2 and 3 are set to lengths with which even though gaps 9 and 10 between a main body frame 1 and a building construction in a longitudinal direction of the main body frame 1 become 0, the main body frame 1 does not drop out. The gap 10 at an opposite side is set larger than the gap 9 at a side where a driving device 12 is arranged, of the gaps 9 and 10 between the main body frame 1 and the building construction in the longitudinal direction of the main body frame 1. The strength of the supporting angle 2 at a side where the driving device 12 is arranged, of the one and the other supporting angles 2 and 3, is set to be larger than the strength of the supporting angle 3 at the opposite side.SELECTED DRAWING: Figure 1 |
