To provide a passenger conveyor that enables the work of installing fastening metal fittings while the existing passenger conveyor is suspended over a construction beam.SOLUTION: A passenger conveyor is equipped with a truss frame 4 and a truss support device 8 including a truss support member 9. The truss frame 4 is installed onto a building beam 7 via a truss support device 8. The truss support member 9 has a notch 11 or a cutout that forms an opening in the truss support member 9 in a range inside the truss frame 4 in a width direction W. The truss support device 8 comprises: a fastening metal fitting 10 fixed to the building beam 7 and at least partly located inside the opening 11; and a guide material 12 provided on the truss support member 9 and located on both sides 10a, 10b of the fastening metal fitting 10 in the width direction W of the truss frame 4, and having limiting portions 12a, 12b that limit displacement of the truss support member 9 in the width direction W relative to the fastening metal fitting 10.SELECTED DRAWING: Figure 2 【課題】本発明の目的は、既設乗客コンベアが建築梁に架かった状態で、止め金具を設置する作業を可能とした乗客コンベアを提供することにある。【解決手段】乗客コンベアは、トラスフレーム４と、トラス支持部材９を含むトラス支持装置８と、を備え、トラス支持装置８でトラスフレーム４を建屋梁７に架設する。トラス支持部材９は、幅方向Ｗにおけるトラスフレーム４の内側の範囲に、トラス支持部材９に開口を形成する切り欠き１１又は切り抜きを有する。さらにトラス支持装置８は、建屋梁７に固定され、少なくとも一部が開口１１の内側に位置する止め金具１０と、トラス支持部材９に設けられ、トラスフレーム４の幅方向Ｗにおいて止め金具１０の両側面１０ａ，１０ｂ側に位置して、トラス支持部材９における止め金具１０に対する幅方向Ｗの変位を制限する制限部１２ａ、１２ｂを有するガイド材１２と、を備える。【選択図】図２
