PROBLEM TO BE SOLVED: To remove a tread necessary for maintenance inspection work while keeping a tread arranged adjacently as it is by realizing the slip prevention for a load on the tread with a simple structure.SOLUTION: A slip prevention device or a load on a passenger conveyor tread of this invention, which prevents an unshown load on a tread 5 as the tread 5 is formed in stairs from slipping down from the tread 5, comprises a stopper 10 capable of projecting from the top face 5A of the tread 5 and retreating from the projection state to prevent a load on the tread 5 from slipping down from the tread 5 in the projection state and a roller 12 which moves with changes in height position from a tread 11 arranged adjacently and projects or retreats the stopper 10 to provide each tread with a combination of these stopper 10 and roller 12.

    【課題】踏板上の搭載物の滑落の防止を簡単な構造で実現し、保守点検作業に際し必要な踏板を、隣接して配置された踏板をそのままの状態に維持して取り外すようにする。【解決手段】本発明に係る乗客コンベアの踏板上搭載物の滑落防止装置は、踏板5が階段状に形成されているときの踏板5上の図示しない搭載物の踏板5からの滑落を防止するものであって、踏板5の上面5Aから突出可能、及び突出した状態から後退可能で、突出した状態にあっては踏板5上の搭載物の踏板5からの滑落を防止するストッパ10と、隣接して配置された踏板11との間の高さ位置の変化に応じて移動し、ストッパ10を突出、または後退させるローラ12とを含み、これらのストッパ10とローラ12の組み合わせを踏板毎に設けた構成にしてある。【選択図】図4
