To provide a tension adjustment device which can maintain a contact state of a trolley wire and a pantograph in good condition by reducing error from setting tension by reducing friction force in a slide part of the tension adjustment device.SOLUTION: In the tension adjustment device 1 which is attached to the trolley wire 10 and includes tension adjustment means for adjusting tension force of the trolley wire 10, the tension adjustment means comprises a pulley 12 which is attached on one end of the trolley wire 10, a weight 13 which extends in a tangential direction of the pulley 12 and vibration addition means 30 which operates infinitesimal high frequency vibration on a movable part of the tension adjustment device.SELECTED DRAWING: Figure 1

    【課題】張力調整装置の摺動部における摩擦力を低減して設定張力からの誤差を低減することで、パンタグラフと電車線の接触状態を良好な状態に維持することができる張力調整装置を提供する。【解決手段】電車線10に取り付けられ、電車線10の張力を調整する張力調整手段を有する張力調整装置1であって、張力調整手段は、電車線10の一端に取り付けられた滑車12と、滑車12の接線方向に延びる重錘13と、張力調整装置の可動部に微小な高周波振動を作用させる振動付加手段30と、を備える。【選択図】図1
