To provide an attachment member which can prevent a load from being transmitted to a pillar band to prevent damage of the pillar band in a case that a tension adjustment device swings during an earthquake and inhibit increase of the weight.SOLUTION: An attachment member 20 includes: a first member 21 attached to a support pillar; and a second member 31 attached to a tension adjustment device connected to an electric car track. The first member 21 and the second member 31 are assembled in a manner that the members can rotate relative to each other by a rotary shaft 22 extending in a direction intersecting with a horizontal direction. The rotary shaft 22 is a bolt-like member and a nut 23 is attached to the tip side of the rotary shaft 22 to form a removal prevention mechanism.SELECTED DRAWING: Figure 2
【課題】地震時に張力調整装置が動揺した場合に、支柱バンドに荷重が伝達しないようにして支柱バンドの破損を防ぐと共に、重量増加を抑えることができる取付部材を提供する。【解決手段】取付部材20は、支柱に取り付けられる第1の部材21と、電車線に接続される張力調整装置に取り付けられる第2の部材31を備える。第1の部材21と第2の部材31は、水平方向と交差する方向に延びる回動軸22によって互いに回動自在に組み付けられる。なお、回動軸22は、ボルト状の部材であって、先端側にナット23が取り付けられて抜け止め機構を構成している。【選択図】図2
