To reduce load on a maintenance worker lifting a step in order to check a space between a com and a cleat in a passenger conveyor.SOLUTION: A step lifting assistance device 80 for a passenger conveyor has a guide cylindrical body 82 having a truss interior abutting portion at a lower end, a guide opening at an upper end, and a guide hole in an axial direction. The step lifting assistance device also has a movable rod body 84 having a step abutting portion at an upper end, smaller in diameter than an inside diameter of the guide hole, and slidable in the guide hole while a lower end side is kept inserted in the guide cylindrical body. The step lifting assistance device further has a connection string body 86 one end of which is fixed to the lower end side of the movable rod body 84 and the other end of which is exposed from outside of the guide cylindrical body 82 on an upper-end side of the guide cylindrical body 82. The step lifting assistance device also has an operation unit 88 having an outer cylindrical portion larger in diameter than an outside diameter of the guide cylindrical body 82 and an operation rod portion extending in a direction perpendicular to an axial direction of the outer cylindrical portion, and to which the other end of the connection string body exposed from the outside of the guide cylindrical body is fixed.SELECTED DRAWING: Figure 2

    【課題】乗客コンベアにおけるコムとクリートとの間隙確認のためにステップを持ち上げる保守作業員の負荷を軽減することである。【解決手段】乗客コンベアのステップ持上支援装置80は、下端部にトラス内当接部、上端部にガイド開口部を有し、軸方向にガイド穴を有するガイド筒体82を有する。また、上端部にステップ当接部を有し、ガイド穴の内径よりも小径で、下端部側をガイド筒体に挿入した状態でガイド穴内を摺動可能な移動棒体84を有する。さらに、一端部が移動棒体84の下端部側に固定され、他端部は、ガイド筒体82の上端部側でガイド筒体82の外側に出ている接続紐体86を有する。そして、ガイド筒体82の外径よりも大径の外筒部、及び、外筒部の軸方向に垂直な方向に延伸する操作棒部を有し、ガイド筒体の外に出た接続紐体の他端部が固定されている操作部88を有する。【選択図】図2
