PROBLEM TO BE SOLVED: To provide a movable bracket which can reduce impact load given onto an insulator at the time of occurrence of an earthquake and can protect the insulator from breakage.SOLUTION: In a movable bracket 1, a fragile site 12 which has a downward bending resistant load lower than that of other sites is formed between a connection part 6 for connection to an oblique main pipe 5 and a connection part 11 for connection to a trolley wire support component 7 in a horizontal main pipe 3. When an excessive downward impact load due to an earthquake or the like is given onto the horizontal main pipe 3, the fragile site 12 of the horizontal main pipe 3 is firstly deformed, whereby an impact load given onto an insulator 4 is reduced and the insulator 4 can be protected from breakage.SELECTED DRAWING: Figure 1

    【課題】碍子に伝わる地震時の衝撃荷重を低減させ、碍子を破壊から守ることができる可動ブラケットを提供する。【解決手段】可動ブラケット1においては、水平主パイプ3における斜主パイプ5との結合部6とトロリ線支持部材7との結合部11との間に、下方への曲げ耐荷重が他の部位よりも低い脆弱部12が形成される。地震等による下方への過大な衝撃荷重が水平主パイプ3にかかったときに、水平主パイプ3の脆弱部12を先に変形させることにより、碍子4に伝わる衝撃荷重を低減させ、碍子4を破壊から守ることができる。【選択図】図1
