た。In a hose using such a PVC resin, dioxin and the like which are harmful to the human body are generated when incinerated like garbage in disposal after disposal. It has become a social problem. When the resin material is PVC, the specific gravity is large,
For a hose that uses both a hard steel wire for retaining the shape of the hose and a copper wire for energizing, the overall weight of the hose is large, and if it is used for a long time, the fatigue will be large and the cost will be optimal. There was a problem that it could not be said to be something.

It has been confirmed that it has the advantage that the feeling of fatigue can be minimized even with the use of time, but it is assumed that the tube wall has sufficient flexibility and flexibility in use. It was confirmed that the abrasion resistance was inferior, and particularly, the outer peripheral surface of the reinforcing wire was severely worn, and it was difficult to obtain a product suitable for long-term use. Therefore, as a means of increasing the abrasion resistance, the thickness of the tube wall was increased, or a hose was manufactured using a material having high hardness, and the use test was repeated. It was confirmed that the hose was damaged or that the entire hose was heavy and unsuitable for long-term use.

Although it is a hose that does not become a source of generation, it has the advantage of being excellent in shape retention, light weight of the whole hose, easy to handle, and capable of minimizing the feeling of fatigue even when used for a long time, Further, it is an object of the present invention to provide a hose which has less stickiness and also has wear resistance.

る。In the hose shown in the first embodiment, as shown in FIG. 2, the thickness of the tube wall 5 is made as thin as possible, and the entire tube wall is made substantially uniform. The hose has a large thickness and is formed by laminating an abrasion-resistant linear portion 4 on an outer surface portion covering the coated steel wire 3. The hose shown in the second embodiment is shown in FIG. As a result, the wall thickness of the pipe wall 5 is made slightly thicker, only the portion covering the outer peripheral surface of the coated steel wire 3 is made thinner partially, and the wear-resistant linear portion 4 is formed on the thinner portion. Thus, the entire tube wall 5 has a substantially uniform thickness. However, since these examples show typical forms, the present invention is carried out with appropriate modifications such as changing the intermediate form of these two forms and the coating thickness of the coated steel wire 3 to an appropriate thickness. can do.

Since the resin material of the part, and furthermore, any of the adhesives, use a non-chlorine-based specific resin material that does not generate toxic gases such as dioxin when burned, A flexible hose that does not cause pollution during incineration can be obtained.

As it has the advantage of being able to withstand long-term use, it has excellent abrasion resistance, without being damaged by disorder, because the friction-resistant linear portion with high hardness takes on drag friction and contact scratch resistance. There is also an effect that the urethane resin material having low hardness, which is felt when gripped, has an advantage of reducing stickiness.

疲れを軽減させることができる利点がある。The flexible hose according to the present invention has a specific gravity of 1.2 to 1.3 in the case of PVC resin which has been conventionally used as a hose material. In the case of the urethane resin to be used, the specific gravity is 1.1 to 1.2 on average. Therefore, when the volume of the tube wall forming material to be used is the same, compared to the PVC resin hose, a simple calculation is performed. The weight of the tube wall can be reduced by 10% or more. In the case of urethane-based resin, it has excellent sliding wear and scratch resistance, excellent mechanical strength against tensile and tearing forces, and excellent weather resistance. Because there is PVC
Since the average wall thickness of the tube wall can be reduced as compared with the resin hose, the weight of the hose can be further reduced, and there is an advantage that fatigue during use can be reduced.
