To provide a spring type tension balancer for overhead line which can easily perform tensile force fine adjustment with simple configuration, and maintains safe electric car operation.SOLUTION: A spring type tension balancer for overhead line comprises an outer cylinder 2 of which one end is connected to a support structure, an inner member 3 of which one end is connected to an overhead wire and the end side is inserted into the other end side of the outer cylinder 2 so as to be freely move in and out, and a coil spring 6 which is interposed between the outer cylinder 2 and the inner member 3 and energizes the inner member 3 projected from the outer cylinder 2 so as to pull the same into the outer cylinder 2, and detains the overhead wire in the support structure while maintaining a prescribed tensile force. The balance comprises a spring force adjustment member 8 which changes a compression length of the coil spring 6 by intervening between the other end of the outer cylinder 2 and one end of the coil spring 6 from an external side of the outer cylinder 2. The spring force adjustment member 8 comprises a push screw 9 which penetrates the outer cylinder 2 in an axial direction, and a lock piece 11 which is movable in the axial direction between the outer cylinder 2 and the inner member 3 by fastening the push screw 9, and changes the compression length of the coil spring 6 with the lock piece 11 by fastening the push pin 9.SELECTED DRAWING: Figure 2

    【課題】 簡易な構成で張力の微調整を簡単に遂行でき、電車の安全な運行を維持する架空線用ばね式テンションバランサを提供する。【解決手段】 一端が支持構造物に連結される外筒2と、一端が電車線に連結され他端側が外筒2の他端側に出入り自在に挿入された内側部材3と、外筒2と内側部材3との間に介設され外筒2から突出した内側部材3を外筒2内へ引き込むように付勢するコイルばね6とを具備させ、電車線を所定の張力を保持しつつ支持構造物に引き留める。外筒2の他端とコイルばね6の一端との間に外筒2の外側から介入することによりコイルばね6の圧縮長を変更するばね力調整部材8を具備させる。ばね力調整部材8は、外筒2を軸線方向に貫通する押しねじ9と、押しねじ9の締め込みにより外筒2と内側部材3との間を軸線方向に移動自在の係止片11とを具備させ、押しねじ9の締め込みにより係止片11でコイルばね6の圧縮長を変える。【選択図】 図2
