<P>PROBLEM TO BE SOLVED: To provide a fall prevention hook for a material and equipment, which reliably prevents the occurrence of a situation that the material and equipment may fall due to a rope disengaged from the hook without being intended by a worker, when retaining the rope for hanging down a variety of the materials and equipment to the fall prevention hook attached to the worker. <P>SOLUTION: This fall prevention hook is constituted of a claw-shaped hook part, and closing metal fittings which are attached to the hook part so as to be turnable via a shaft support, and energized by an elastic member so as to maintain a state that the hook part is closed. A lock lever is arranged at the base end side of the closing metal fittings, and the lock lever is attached to the closing metal fittings at its base end so as to be turnable via the shaft support while being coated with a constituting member of the closing metal fittings. The tip of the lock lever abuts on the constituting member of the hook part, and inhibits the closing metal fittings to turn in a direction in which the hook part is released. <P>COPYRIGHT: (C)2012,JPO&INPIT |
