Description of the Related Art Conventionally, as a pressure-resistant hose of this type, for example, a reinforcing wire having a circular cross section made of a hard synthetic resin is formed on the outer peripheral surface of a hose body made of a soft synthetic resin as disclosed in JP-A-11-201341. There is a structure in which a reinforcing fiber layer in which a monofilament is knitted in a cross shape is coated on the outer periphery of these is wound so as to project outward. When the internal pressure of the hose body rises to a high pressure, the concave part corresponding to the pitch of the reinforcing wire rod of the hose body bulges outward and contacts the reinforcing fiber layer to be reinforced, and as a result, it withstands the high pressure. At the same time, the frictional resistance at the time of contact with the ground is reduced. A connecting structure for connecting a hose joint to a connection end of a pressure-resistant hose of this type has a nipple portion of the hose joint inside the hose body with a metallic caulking cap covered on the outside of the reinforcing fiber layer. It is general that the hose body and the reinforcing fiber layer are sandwiched and fixed between the annular reduced diameter portion and the nipple portion by inserting the plug and inserting the caulking cap into an annular diameter by crimping.

補強繊維層が更に抜け易くなる。However, in such a conventional pressure-resistant hose, the concave portion corresponding to the pitch between the reinforcing wire rods of the hose body bulges outward each time the internal pressure of the hose body becomes high. Since it comes into contact with the reinforcing fiber layer with, the inner peripheral surface of the hose body in this high pressure state has irregularities,
Turbulent flow occurs in the fluid passing through it, and as a result, the resistance inside the pipe increases and it is not possible to supply the fluid smoothly.Not only may pulsation and noise occur in the hose, but the internal pressure of the hose body may increase. Each time the height changes, the concave portion corresponding to the pitch of the reinforcing wire material frequently expands and contracts, which shortens the life of the hose body and may not be used for a long period of time. Furthermore, since the outer wall surface of the hose protrudes in a corrugated shape by wrapping the reinforcing wire outwardly around the outer peripheral surface of the hose body, when the reinforcing fiber layer is knitted along the outer circumference of the hose, the reinforcement protruding spirally. In the wire portion, the braiding of the reinforcing fiber is likely to be rough, and in the concave portion located between the pitches of the reinforcing wire, the braiding of the reinforcing fiber is likely to be dense, and the braiding cannot be made uniform. Since it is rough, there is a problem that the frictional resistance at the time of ground contact increases. Further, in the conventional pressure-resistant hose coupling structure described above, the annular reduced diameter portion of the caulking cap is pressed against only the outer end of the reinforcing wire that spirally protrudes from the hose body through the reinforcing fiber layer to form a hose body. Since a spiral gap is generated between the hose bodies and the hose joints, it is inferior in airtightness between the hose body and the hose joint, and the concave portion located between the pitches of the reinforcing wire has a high internal pressure of the hose body. Since it is configured to swell outwards every time, fluid leakage easily occurs between the outwardly bulging concave portion and the nipple portion,
There is a problem that it may cause the hose to come off. Furthermore, the force for fixing the reinforcing fiber layer is insufficient and it is slippery, and when a force acts in the direction of pulling it out from the caulking pipe, the reinforcing fiber is separated and easily comes off. Once the reinforcing fiber layer comes off from the caulked pipe, the connecting end of the hose body is exposed, and the pressure resistance of this exposed part is significantly reduced compared to other covered parts, and there is a risk of puncture. In addition, there is a problem that the nipple portion of the hose joint is easily removed from the hose body. Especially when used as a water supply hose for a washing machine, the water supply to the washing machine is frequently stopped by the solenoid valve, so a water hammer occurs each time and the internal pressure of the hose body rises sharply. , The hose body repeats expansion and contraction alternately,
The reinforcing fiber layer becomes easier to come off.

Therefore, there is no turbulence in the fluid passing through it. Further, even if a force acts on the reinforcing fiber layer 2 in the pulling direction from the caulking pipe 4, since the reinforcing wire 2 is completely embedded in the hose body 1 made of a soft resin, the reinforcing fiber does not fall apart.

ル部Ｂ１と接触しないようにすることもできる。Further, since the reinforcing wire 2 is covered with the reinforcing fiber layer 3 and is reinforced, the thickness can be reduced, and as a result, even if the reinforcing wire 2 is pressed due to caulking, only the hose main body 1 is pressed. By changing the shape, the reinforcing wire 2 is prevented from coming into contact with the nipple portion B1 of the hose joint B and causing fluid leakage. For the same purpose and effect, the reinforcing wire 2 is made harder than the reinforcing fiber layer 3 but deformable so that the reinforcing wire 2 can be deformed in accordance with caulking, so that the reinforcing wire 2 is hose jointed. It is also possible to prevent the reinforcing wire 2 from coming into contact with the nipple portion B1 of the hose joint B by making it not come into contact with the nipple portion B1 of B or by making the hose body 1 thick.
