PROBLEM TO BE SOLVED: To provide a high-pressure hydraulic hose which is excellent in adhesiveness between a reinforcement layer made of plated wire and a rubber layer and has improved durability without using an adhesive (in adhesive-free condition).SOLUTION: A high-pressure hydraulic hose includes an inner surface rubber layer 1, a reinforcement layer 4 made of plated wire located on the outer side of the inner surface rubber layer and a rubber layer 3 in contact with the reinforcement layer 4. Therein, the rubber layer 3 is made of a rubber composition containing the following (A) to (C). (A) is a diene type rubber, (B) is a phenol type resin modified with a functional group having a double bond and (C) is at least one side of a vulcanizer having morpholine structure and a vulcanization accelerator having morpholine structure. |
