To provide a tension balancer for an overhead line which can elongate a stroke length within a range of a load which is set by reducing a hysteresis loss of a deflection-load characteristic.SOLUTION: An outside wire rod 201 and/or an outside auxiliary washer 102b for prohibiting the contact of an outside spring washer 102a and an outside cylinder member 101 is arranged between the outside cylinder member 101 and a first intermediate cylinder member 102, and the friction resistance of the outside wire rod 201 or the outside auxiliary washer 102b with respect to the outside spring washer 102a or the outside cylinder member 101 is lower than the friction resistance of the outside spring washer 102a with respect to the outside cylinder member 101.SELECTED DRAWING: Figure 1
【課題】たわみ−荷重特性のヒステリシス損失を低減することによって設定された荷重の範囲内でストローク長を増大することができる架空線用テンションバランサを提供する。【解決手段】外側筒部材101および第1中間筒部材102の間に、外側ばね座金102aと外側筒部材101との接触を阻止する外側線材201および/または外側補助座金102bを設け、外側線材201または外側補助座金102bは、その外側ばね座金102aまたは外側筒部材101に対する摩擦抵抗が外側ばね座金102aの外側筒部材101に対する摩擦抵抗よりも小さい。【選択図】図1
