Summary:PROBLEM TO BE SOLVED: To provide a medium transferring hose of high durability and production efficiency of the hose respectively by reducing yarn fatigue caused by repetitive bending or pressure, and spirally braiding the reinforcing yarns around the outer periphery of an inner tube. SOLUTION: A medium transferring hose is prepared by laminating sequentially a first reinforcing yarn layer, a second reinforcing yarn layer, and an outer rube on an outer peripheral surface of an inner tube. The first reinforcing yarn layer is composed of reinforcing yarn spirally wound around the outer periphery of the inner tube. The second reinforcing yarn layer is composed of reinforcing yarn spirally wound round the outer periphery of the first reinforcing yarn layer in the opposite direction to the winding direction of the first layer. The braid density of the reinforcing yans of the first and second layers is 70% or more. The first and second reinforcing yarns are twisted yarns, while their first twist and final twist numbers are both 8 times/10 cm or more.
