Date Aug. 28, 1997A refrigerant conveying hose, being wholly made of a synthetic resin, is formed of an inner tube forming an inner side layer, an intermediate layer on the outer periphery surface of the inner tube, a fiber reinforced layer on the outer periphery surface of the intermediate layer and an outer tube forming the outer covering layer. The inner layer is formed of any one of (1) an thermoplastic resin alloyed of a polyamide resin and an olefin based elastomer, (2) an thermoplastic resin alloyed of a copolymer of a polyamide resin and an olefin based elastomer, (3) an thermoplastic resin alloyed of a polyamide resin and an urethane based elastomer and (4) an thermoplastic resin alloyed of a copolymer of a polyamide resin and an urethane based elastomer, the intermediate layer is formed of an thermoplastic resin material alloyed of a polypropylene (PP) and a isobutylene-isoprene rubber (IIR), an adhesive for bonding the inner tube and the intermediate layer is formed of a specific resin based adhesive, the outer tube is formed of an thermoplastic resin material alloyed of a polypropylene (PP) and an ethylene propylene diene monomer rubber (EPDM), and the resulting hose is molded out thereof.
