PURPOSE: To provide a high pressure hose for a cooling medium not generating the slipping of a reinforcing yarn to a lower layer while having a simple structure eliminating the intermediate rubber layer between two spirally wound reinforcing layers and having pressure resistance and durability equal to those of a conventional intermediate rubber layer. CONSTITUTION: A high pressure hose for a cooling medium is constituted of a inner surface resin tube 1, the inside rubber layer 2 provided on the outer peripheral surface of the tube 1, the first reinforcing layer 3 formed by spirally winding a plurality of arranged reinforcing yarns around the outer peripheral surface of the rubber layer 2, a second reinforcing layer 5 formed by spirally winding a plurality of arranged reinforcing yarns around the outer periphery of the first reinforcing layer 3 is the direction reverse to that of the layer 3 and the outside rubber layer 6 provided on the outer periphery of the second reinforcing layer 5 and the inside rubber layer 2 is composed of a rubber material of which the 50% modulus M50 at 135 deg.C is 20-40kgf/cm<2> . |
