PROBLEM TO BE SOLVED: To improve a point that, in a suspender categorized in a type that a holding part holds a plate heavy product in a sandwiching manner and this item is suspended with a falling prevention hook in a slightly lifted state, the falling prevention hook is accidentally opened or closed.SOLUTION: A plate connected to wire and the like is suspended. A main body comprises at least a pair of holding part holding the plate on its side surface with a sandwiching presser, and a falling prevention hook 3 supporting the plate from its side surface to bottom. The holding part is connected to a holding part opening/closing linking mechanism and closed by self-weight and the weight of the plate. The falling prevention hook 3 is rotatably connected to an axis arranged adjacent to a connecting part to a holding part as a tip end of the holding part opening/closing linking mechanism, and connected to a falling prevention hook opening/closing linking mechanism different from the linking mechanism connected to the holding part. A through hole 41 and a notch 42 are formed on the holding part opening/closing linking mechanism. A pin locking tool 22 slidably holding a rotatable locking pin fitting into the through hole or notch is fixed on a falling prevention hook opening/closing mechanism.
【課題】把持部で板状重量物を挟持し、これを少し持ち上げた状態で落下防止フックにて吊持するタイプの吊り具において、落下防止フックが不用意に開いたり閉じたりする点を改善する。【解決手段】ワイヤ等に連結した板状体を吊持するもので、本体には、板状体を側面から挟圧把持する少なくとも一対の把持部と、板状体をその側面から底面にかけて支持する落下防止フック3を備えており、把持部は把持部開閉リンク機構に連結され自重と板状体重量で閉じられ、落下防止フック3は、把持部開閉リンク機構の先端である把持部との連結部近傍に設けられた軸に可回動に連結され、把持部に連結されたリンク機構とは別体の落下防止フック開閉リンク機構に連結されており、また把持部開閉リンク機構には透孔41又は切欠42が設けられ、落下防止フック開閉機構には透孔又は切欠に嵌り込む回動係止ピンを摺動自在に保持するピン係止具22が固設されている。【選択図】図3
