To provide a chain elongation detection device for passenger conveyors that can accurately detect chain elongation.SOLUTION: The chain elongation detection device comprises: a support member that rotates one sprocket of a pair of sprockets over which a chain to be detected for elongation is hung, and that supports the one sprocket at a variable distance from the other sprocket; a tensioning member that increases the tension of the chain between the pair of sprockets through the support member; and a chain elongation detection unit that outputs an elongation detection signal to the effect that the amount of elongation of the chain exceeds a predetermined amount when the amount of movement of the support member from a predetermined reference position in the direction exceeds a predetermined amount of movement.SELECTED DRAWING: Figure 2

    【課題】チェーンの伸びを正確に検出することができる乗客コンベアのチェーン伸び検出装置を提供する。【解決手段】伸び検出対象のチェーンが掛け渡された一対のスプロケットのうち、一方のスプロケットを回転可能、かつ、一方のスプロケットを他方のスプロケットとの間の距離を可変可能に支持する支持部材と、支持部材を介して一対のスプロケットの間のチェーンの張力が高くなる方向に付勢する付勢部材と、前記方向における支持部材の所定の基準位置からの移動量が所定の移動量を超えた場合に、チェーンの伸び量が所定の伸び量を超えた旨の伸び検出信号を出力するチェーン伸び検出部と、を備える。【選択図】図2
