Patent ID: 7870876

Claim:
A hose comprising hard synthetic resin reinforcement materials spirally fed, the hose having a top part with two sides, and having, on both of the two sides of the top part thereof in the tube axial direction, receiving surfaces positioned on the radial inner side toward the end part thereof and a soft synthetic resin hose body for covering the spirally fed reinforcement materials, wherein the reinforcement materials are spirally fed in the state of the top parts being positioned on the radial outer side thereof, a soft synthetic resin tape material is fed to the fed reinforcement materials, and while covering parts projected in a generally arc shape to the center of the hose are formed between the reinforcement materials, the tape material is fixed to the surfaces of the reinforcement materials by melting the tape material or with an adhesive agent, and thus the hose body having a generally flat inner surface and formed in a generally circular shape in cross section can be provided, and wherein the tape material has a width of approximately one pitch extending over two reinforcement materials adjacent to each other in the longitudinal direction of the hose body, and the hose body is formed by melt-welding tape materials adjacent to each other in the longitudinal direction of the hose body in a partly overlapped state to the reinforcement material.
