置。[Claims for Utility Model Registration] 1. A winding spring 3 is interposed between the winding drum 1 and the main shaft 2 to automatically wind the rope, and the rotational speed of the winding drum 1 when the rope is pulled out is set to a default value. The centrifugal clutch mechanism 4 attached to the winding drum 1 is activated to stop the rotation of the winding drum 1 when the rotation speed exceeds 1, and the disc pad 51 is provided on the winding drum 1. The lock plate 5 that engages with the lock pawl 41 is screwed onto the main shaft 2, and the brake plate 21 is provided integrally with the main shaft 2 so as to face the disc pad 51. The lock plate 5 and the brake plate 21 are connected by screws 52 of a predetermined strength. The lock plate 5 and the main shaft 2 are screwed together in the direction of the brake plate 21 by engagement with the lock pawl 41, and the screw 52 is cut.
This fall prevention device has an indicator pin 53 which is inserted from the outside of the brake plate 21, has its tip in contact with the lock plate 5, and is pushed and protruded by the movement of the lock plate 5 so that it can be confirmed from outside the frame 6. 2. The fall prevention device according to claim 1, wherein the breaking strength of the screw 52 is set to 200 to 400 kg. 3. The fall prevention device according to claim 1 or 2, wherein the end of the display pin 53 opposite to the lock plate 5 is exposed on the outer surface of the frame 6. 4 Brake plate 2 where display pin 53 is located
1. A fall prevention device according to claim 1 or 2 of the utility model registration claim, in which a confirmation window is provided in the frame 6 on the top of the fall prevention device.
