PROBLEM TO BE SOLVED: To provide a plurality of passenger conveyors each of which is provided with a structure that prevents each passenger conveyor from dropping down from a building even when an unexpected large-scale earthquake occurs for the plurality of passenger conveyors installed side by side in a width direction in a parallel manner or an intersecting manner in the building.SOLUTION: Passenger conveyors (a) and (b) according to this embodiment are provided with support angles (1a) and (2b) for supporting trusses of the passenger conveyors (a) and (b) with respect to a building at boarding and alighting sides thereof. One support angle (1a) out of the support angles (1a) and (2b) of the passenger conveyors (a) and (b) adjacent to each other at any floor is set to a fixed support with respect to the building, and the other support angle (2b) is set to a non-fixed support with respect to the building. A beam material 10 that protrudes below a truss bottom surface 9 of the adjacent passenger conveyor (b) having the support angle (2b) as the non-fixed support so as to overlap with the truss bottom surface 9 while being fixed to a truss bottom surface 8 of the passenger conveyor (a) having the support angle (1a) as the fixed support is provided. |
