Abstract: PURPOSE: To enable passing gas in a rubber hose, conveying freon gas, etc., to escape outside effectively without causing swell to inside or outside surface by making tight attachment of inside tube rubber to a reinforcing layer's fiber cord.  
     CONSTITUTION: A rubber hose 1, designed for conveying freon gas, etc., and is composed of an inside tube rubber 2, a reinforcing layer 3 and an outside covering rubber 4, is constituted in such a manner that a fiber cord of the reinforcing layer 3 provided on outside of the inside tube rubber 2 is tightly and completely attached to the inside pipe rubber 2.
