method of manufacturing rubber hose, rubber hose, and the terminal fitting with a rubber hose

摘要

A method of manufacturing a rubber hose that includes an inner rubber tube having a hollow portion, first and second braided layers formed by braiding strands, and an outer rubber tube. The method includes forming a laminated structure by sequentially forming the first braided layer on the inner rubber tube, a thermoplastic resin layer including a thermoplastic resin on the first braided layer, the second braided layer on the thermoplastic resin layer and the outer rubber tube on the second braided layer, vulcanizing the inner rubber tube and the outer rubber tube and softening the thermoplastic resin layer by heating the laminated structure to not lower than a softening temperature of the thermoplastic resin layer, and integrating the first and second braided layers by softening the thermoplastic resin layer and then solidifying the soft thermoplastic resin penetrated into mesh openings formed between the strands.
