To provide a load hanging hook capable of always preventing a load body from being disengaged from a hook part even in use where the load body carried to various place and hung.SOLUTION: A load hanging hook 1 has: a base member 10 that is suspended by a traction member 150; a movable member 20 that is supported so as to be movable between an opening position and a closing position with respect to the base member 10 and interlocked with winding/drawing driving of the traction member 150; and a spring 45 that generates a biasing force so as to move the movable member 20 from the closing position to the opening position. The movable member 20 is supported so as to be movable to the closing position side against the biasing force of the biasing member 45 when tension is applied on the traction member 150.SELECTED DRAWING: Figure 2
【課題】様々な個所に荷重体を搬送して荷下げするような使用態様であっても、荷重体がフック部分から外れることがない荷下用フックを提供する。【解決手段】荷下用フック1は、牽引部材150によって吊り下げられるベース部材10と、ベース部材10に対し開位置と閉位置との間で移動可能に支持されるとともに、牽引部材150の巻き上げ/引き出し駆動と連動する可動部材20と、可動部材20を閉位置側から開位置側に移動するように付勢力を発生させるバネ45と、を有する。可動部材20は、牽引部材150に張力が作用した際に、付勢部材45の付勢力に抗して閉位置側に移動可能に支持されている。【選択図】 図2
