To simply and accurately detect an abnormality of a wheel of a step.SOLUTION: A passenger conveyor according to an embodiment comprises: a first member that is provided on a traveling surface of one of a pair of wheels of one of a pair of guide rails, supports a part of the one wheel, and tilts the one wheel when the one wheel is in a rattling state; a second member that is provided on a traveling surface of the other of the pair of wheels of the other of the pair of guide rails and at a position opposed to the first member to allow the other wheel to float; and an abnormality detection unit that detects a rattling state of the one wheel based on the inclination of the one wheel in the first member. The abnormality detection unit includes: a sound collector provided on a traveling path of the pair of wheels; and a detection unit that detects a rattling state of the wheel based on traveling sound of the wheel collected by the sound collector.SELECTED DRAWING: Figure 12

    【課題】踏段の車輪の異常を簡易かつ構成度に検出すること。【解決手段】実施形態の乗客コンベアは、一対の案内レールのうち一方の案内レールの一対の車輪のうち一方の車輪の走行面に設けられ、前記一方の車輪の一部を支持して前記一方の車輪ががたつき状態である場合に前記一方の車輪を傾斜させる第1の部材と、前記一対の案内レールのうち前記一方の案内レールに対する他方の案内レールの前記一対の車輪のうち前記一方の車輪に対する他方の車輪の走行面であって、前記第1の部材と対向する位置に設けられ、前記他方の車輪を浮かせた状態にさせる第2の部材と、前記第1の部材における前記一方の車輪の傾斜に基づいて、前記一方の車輪のがたつき状態を検出する異常検出部と、を備え、前記異常検出部は、前記一対の車輪の走行経路上に設けられた集音部と、前記集音部で集音された前記車輪の走行音に基づいて、前記車輪のがたつき状態を検知する検知部と、を備える。【選択図】図12
