Claims

[Scope of Claim for Utility Model Registration] In a rubber hose for pipe expansion with reinforcing cloth, which is formed by integrally extruding an inner rubber and an outer rubber with a reinforcing cloth interposed between them and extending in the radial direction of the hose, the above-mentioned reinforcement is provided. 1. A rubber hose filled with reinforcing cloth for tube expansion, characterized in that the cloth is provided with cloth threads parallel to the axial direction of the hose to prevent the reinforcing cloth from stretching in the axial direction of the hose.
