具２等を取り外していた。(Prior art) Conventionally, the overhead wire method for stretching the wire without cutting it between multiple steel towers involves installing a wire drum in front of the tower and installing a wire winding machine in front of the multiple towers. The filament wound around the filament drum is stretched with a wire or the like, and after the stretching is completed, a suitable catenary is provided on the filament and the filament is tightened for attachment to a tensioning device. For example, this tension method is
As shown in the figure, the wire 1 is located at an appropriate distance from the steel tower.
Attach the come-along tool 2 to the wire and tension the wire 1 between it and the line side of the tensioning device 3 using the wire tensioning wheel 4 and wire 5. Through this tensioning work, a suitable catenary was created. At this point, attach the clamp 6 to the filament 1 and tighten the tension device 3.
Connect the metal fitting on the line side with the clamp 6, then loosen the wire 5, and connect the wire 1 to the tension device 3 and the clamp 6.
After that, the tension wheel 4, come-along tool 2, etc. were removed.

った。(Problem to be Solved by the Invention) However, in the strap 24 of the conventional device described above, the connecting side with the tension device 3 is bent inward, so that the tension at the time of tension is applied to the bent portion 24a. When acting, a bending moment is generated in the bent portion 24a,
As a result, there was a problem in that the strap 24 was easily deformed.
