PROBLEM TO BE SOLVED: To provide an abnormality detecting device of a passenger conveyor and the like which can detect more accurately abnormality of a passenger conveyor, in particular a footstep chain of an inner roller type.SOLUTION: The abnormality detecting device of a passenger conveyor comprises a detecting device which detects change of a position in a vertical direction due to own weight, at a position where the device does not receive force affecting the change in the vertical direction due to the own weight from shafts other than roller shafts of footstep rollers, at one or both of inversion parts at both ends of a passenger conveyor, with respect to footstep chains in which a plurality of footstep rollers are joined with each other in order through a link plate of a roller shaft and endlessly connected between the inversion parts at both ends of the passenger conveyor.SELECTED DRAWING: Figure 3

    【課題】乗客コンベアの特にインナーローラタイプの踏段チェーンの異常をより正確に検出する乗客コンベアの異常検出装置等を提供する。【解決手段】複数の踏段ローラがローラ軸のリンクプレートにより順番に結合されて、乗客コンベアの両端の反転部の間で、無端状に連結された踏段チェーンに対して、前記両端の反転部の一方または両方において、前記踏段ローラの、前記ローラ軸以外から自重による鉛直方向位置の変化に影響を与える力を受けない位置で、自重による鉛直方向位置の変化を検出する検出装置を備えた乗客コンベアの異常検出装置とする。【選択図】図3
