PROBLEM TO BE SOLVED: To provide a safety belt for high-place work that can be manufactured at low cost without using a heat-shrinkable tube in a sewing portion of a flat rope.SOLUTION: A thimble 5 with a central tubular part 5a for making a flat rope circulate and an external periphery of a rope coupling hole of a hook pass internally inside a loop back tip part of a flat rope is mounted, and a folded-back portion of the flat rope folded back in the thimble forms a sewn part. A cover tube 6 of flexible materials is inserted in the flat rope. The cover tube 6 includes a tubular part 7 covering the sewn part 2b of the flat rope, and locking pieces 8, 9 extended along the surface and the back side of the flat rope. The cover tube is moved to the thimble portion with the flat rope mounted thereon, and the sewn part of the flat rope is covered with the tubular part 7 and the surface of the flat rope wound by the thimble is covered with the locking pieces 8, 9 of the cover tube 6, and then the tips of the locking pieces 8, 9 are locked on the tip part of the thimble 5.SELECTED DRAWING: Figure 3 |
