PROBLEM TO BE SOLVED: To provide a rubber hose capable of improving hose durability damaged by contact of a reinforcing wire. SOLUTION: A plurality of wire reinforcing layers 4 are disposed between an inner rubber layer 1 and an outer rubber layer 2 via interlaminar rubber layers 3. The first wire reinforcing layer 4A or second wire reinforcing layer 4B is formed of a flat wire reinforcing layer where a surface in the hose radius direction is formed by spirally winding a flat reinforcing wire fa formed in plane parts a and b. Each of the remaining wire reinforcing layers 4 is formed of a wire reinforcing layer where a reinforcing wire f having circular cross section is spirally wound. COPYRIGHT: (C)2004,JPO
