で散見される。Prior Art and Problems Conventionally, in the case of this type of flexible band for utility poles, the diagonal branch wire stretched across the tightening bolts between the tightening edges of two opposing band pieces is exposed to excessive stress during typhoons, etc. When tension is applied, a force is applied to pull down the tightening bolt, and the band piece rotates downward around the connecting bolt on the other end and slides down, and does not return to its original position when the tension is released. Tame branch lines have been loosened and are no longer of any use, but they can be seen here and there in the city.

A bulging edge is provided outward, the middle part of the bulging edge is bent outward to form a tightening receiving edge, and a tightening bolt through hole is provided in the bulging edge on the tip side of this tightening receiving edge. The left and right bent portions of the tightening receiving edge of the band piece are made to protrude to form the maximum width portion.

As shown in the figure, the downward rotation of the band piece A around the connecting bolt 9 due to the component force T' under the tension of the branch line is prevented by tightening the belt piece A closest to the load point among the band pieces A that are in close contact with the utility pole D. The reinforcing edge 4 provided on the bent portion of the receiving edge serves as a fulcrum and blocks the bending load, and the load is simply converted into a bending load on the reinforcing edge 4 of the tightening receiving edge 5, thereby preventing the band piece A from slipping down. On the other hand, the 4 reinforcing edges have the widest width as described above and have a cross-sectional series that sufficiently corresponds to the bending load, so they can withstand heavy loads, so that it is possible to increase the size of the entire band piece, etc. Without using any materials, it is possible to effectively prevent the band piece A from slipping down and also to improve the breaking strength, which has great practical value from the viewpoint of safety and economy.
