o will occur.

The dead point described above occurs due to so-called binding (the fastening force is directed toward the center of the object).

The present invention aims to provide a fastening band that does not cause this dead point to occur.

[Means to solve the problem]

The basic structure of the fastening band according to the present invention will be explained below with reference to FIG.

As is clear from the figure, the fastening band T is not different from the known example in that it is composed of a fastening portion 2 and a band portion 1. The feature of the fastening band according to the present invention is that the fastening hole 3 is formed in the same direction as the contact surface 21 to the object 5 to be fastened, as is clear from the comparison with the conventional example. .

Note that numerals 13 and 31 all indicate sawtooth.

[For production]

The chain diagram in FIG. 1 shows the state in which the fastening band of the present invention is wrapped and tightened around the object 5 to be fastened, and as is clear from the figure, the fastening hole 3 of the fastening portion 2 and the The relationship between the band 12 that engages with the saw teeth 31 in the hole and maintains the tightened state is maintained by a tensile force in the tangential direction to the outer peripheral surface of the object 5 during tightening, and is so-called. It is fastened with a buckle. Therefore, no dead point occurs.

(Example) An example of the present invention will be described below with reference to FIG.

Note that the same reference numerals in the drawings as those shown in the first drawing represent members having the same effect as those shown in the same drawing.

As is clear from the figure, in this embodiment, the contact surface 21.11 to the object to be fastened, including the connecting portion between the fastening portion 2 and the band portion 1, is It is formed as a curved surface having approximately the same shape as the circumferential surface.
