[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a dust proof or joint bellows made of a hard and flexible material, and a fastening band for fixing objects to be fixed to various equipment connecting parts.

[0002]

2. Description of the Related Art A band main body made of a metal band plate cut to a certain size is rolled into a three-dimensional circular ring that partially overlaps one end side and the other end side, and the diameter is artificially forced. A fastening band for connecting and fixing a rubber hose for feeding various fluids to its joint pipe, an opening / closing cock, and a mouthpiece part of other equipment by contracting and deforming and locking both ends to each other is known. the actual opening flat who also previously
4-107594 , 4-119687 and 4
No. 138188 was proposed.

In these prior inventions, the band main body of the tightening band does not exert the spring action of expanding and contracting in the radial direction, but the rubber hose relating to the fixed object is itself a flexible soft product. Therefore, the band main body is closely attached to the entire surface of the rubber hose without a gap, and it is possible to firmly and stably tighten the band hose without the risk of displacement or dropping.

However, as in the case of molding various bottles, for example, the bellows for dustproofing and joints blow-molded from thermoplastic plastics are hard products which have substantially no elasticity, and therefore they are used. The above-mentioned tightening band cannot firmly tighten the connection part of various devices.

This is because, as described above, the band main body of the lid does not have the elasticity of expansion and contraction along the radial direction, and as a result, a gap is inevitably formed with the surface of the bellows. If it is used in a vehicle or other equipment that is subject to accidents, etc., there is a risk of misalignment or accidental fall.

[0006]
