To provide a maintenance tool for a passenger conveyor, which can further improve efficiency of detachment work of a guide roller.SOLUTION: A maintenance tool 8 for a passenger conveyor is used for attaching/detaching a guide roller 5 to/from a handrail. The handrail has an ear 7 forming an edge of an opening 6 provided on the backside in a longitudinal direction. The guide roller 5 is inserted from above the opening 6 into the handrail to guide the movement of the handrail. The holding tool 8 comprises a pair of expansion plates 9 and a displacement mechanism 10. The pair of expansion plates 9 oppose each other to be parallel to each other with a horizontal gap. The displacement mechanism 10 is connected to an upper part of each of the pair of expansion plates 9. The displacement mechanism 10 maintains the pair of expansion plates 9 parallel to each other and displaces a gap between the pair of expansion plates 9. The holding tool 8 stands by itself when an outer surface 11 outside each of the expansion plates 9 in a horizontal direction comes into contact with the ear 7 of the handrail from the inside in the horizontal direction and a lower end of each of the expansion plates 9 comes into contact with an inner surface of the handrail from above.SELECTED DRAWING: Figure 8

    【課題】ガイドローラの着脱作業の効率をより高められる乗客コンベアの保守用具を提供する。【解決手段】乗客コンベアの保守用具8は、ガイドローラ5の手摺への着脱に用いられる。ここで、手摺は、裏側に設けられた長手方向に沿う開口6の縁をなす耳部7を有する。ガイドローラ5は、開口6の上方から手摺の内側に挿入され手摺の移動をガイドする。保守用具8は、一対の拡張板9と、変位機構10と、を備える。一対の拡張板9は、左右方向に間隔を開けて互いに平行になるように対向する。変位機構10は、一対の拡張板9の各々の上部に接続される。変位機構10は、一対の拡張板9を平行に保って一対の拡張板9の間隔を変位させる。保守用具8は、各々の拡張板9の左右方向の外側の外面11が手摺の耳部7に左右方向の内側から接触し、かつ、各々の拡張板9の下端が手摺の内面に上方から接触することで自立する。【選択図】図8
