Further, an insertion gap for inserting the rope is formed between the rope engaging claw plate and the rope supporting portion, and the rope is inserted in a direction to reduce the insertion gap width between the rope engaging claw plate and the rope supporting portion. Since a spring for rotating the locking claw plate is provided, and the shape of the outer peripheral edge of the rope locking claw plate is formed into a shape in which the insertion gap width for holding the rope by rotation is gradually narrowed, the bent rope is bent down. The rope pulls the end of the rope to tension the rope (parent rope), and even if a large load is applied to the tensioned rope due to the fall of the worker, the leading edge of the rope locking claw plate strongly clamps the rope at that moment. Since it is pressed, it is possible to prevent the worker from falling down on the ground without fail.
