PROBLEM TO BE SOLVED: To provide a load hanging auxiliary tool capable of improving work efficiency.SOLUTION: A load hanging auxiliary tool 1 has a base body 2, a weight 3, and a hook 4. Backward rotations of the hook 4 to the weight 3 are permitted until a hook base portion 41 abuts on a first rotary shaft 51, and forward rotations of the hook 4 are permitted until the hook base portion 41 abuts on a front regulating portion 31. The weight 3 is hung from the base body 2 and the hook base portion 41 is supported by the first rotary shaft 51, thereby forming a preparation state. When a load is hung from the hook 4, the hook 4 descends while rotating backward, and a gravity center of the weight 3 ascends while the weight 3 rotates backward. The weight 3 rotates until the gravity center of the weight 3 exceeds a top dead point, and the front regulating portion 31 abuts on the hook base portion 41, thereby forming a load hanging state. If a load applied on the hook 4 is released, the weight 3 rotates so as to descend the gravity center of the weight 3, thereby forming a releasing state.SELECTED DRAWING: Figure 5

    【課題】作業効率を向上させることができる荷吊り補助具を提供すること。【解決手段】荷吊り補助具1は、基体2と錘3とフック4とを有する。錘3に対するフック4の後方への回動は、フック基部41が第1回動軸51に当接するまで許容され、フック4の前方への回動は、フック基部41が前方規制部31に当接するまで許容される。錘3が基体2から吊り下がると共にフック基部41が第1回動軸51に支承されることにより、準備状態が形成される。フック4に荷物を吊り下げると、フック4が後方へ回動しながら下降すると共に、錘3が後方へ回動しながら錘3の重心が上昇して、錘3の重心が上死点を超えるまで錘3が回動し、前方規制部31がフック基部41に当接することで、荷吊り状態が形成される。フック4にかかっていた荷重を解放すると、錘3の重心が下降するように錘3が回動し、解放状態が形成される。【選択図】図5
