To provide a tension adjustment device capable of continuously maintaining optimal pressing force for a long period of time.SOLUTION: A tension adjustment device is installed on an endless moving handrail provided on a passenger conveyor for conveying a passenger to adjust the tension of the moving handrail. The tension adjustment device includes a shaft member fixed to a skeleton, a substrate having a center part loosely fitted to the shaft member to be swingable in a circumferential direction of the shaft member, a pair of handrail abutment parts abutting on the moving handrail, a moving part capable of moving vertically with respect to the substrate while supporting the pair of handrail abutment parts, and a pair of energization members energizing the moving part downward with energization force in a predetermined range. When unbalance of force, which is received by the pair of handrail abutment parts from the moving handrail, is about to occur, each of the handrail abutment parts applies uniform energization force on the moving handrail by swinging around the shaft member at a balanced position.SELECTED DRAWING: Figure 2

    【課題】最適な押圧力を長期間維持し続けることができる張力調整装置を提供する。【解決手段】乗客を搬送する乗客コンベアに設けた無端状の移動手すりに配置され、前記移動手すりの張力を調整する張力調整装置であって、躯体に固定した軸部材と、中央部を前記軸部材に遊嵌してあり、前記軸部材の周方向に揺動自在な基板と、前記移動手すりに当接する一対の手すり当接部と、前記一対の手すり当接部を支持すると共に前記基板に対して上下方向に移動可能な可動部と、前記可動部を下方に向けて所定の範囲の付勢力で付勢する一対の付勢部材と、を備え、前記一対の手すり当接部が前記移動手すりから受ける力の不釣合が生じようとすると、釣り合う位置に前記軸部材を中心に揺動することで、各手すり当接部が前記移動手すりに均等な付勢力を作用する、張力調整装置。【選択図】 図2
