PROBLEM TO BE SOLVED: To provide a wear resistant hose which does not cause the deterioration of workability while attaining lifetime extension and cost reduction by the improvement of wear resistance. SOLUTION: The wear resistant hose is constituted such that a middle rubber layer 2 is formed on the periphery surface of a rubber-made inner layer 1, subsequently, a 1st reinforcing layer 3 is formed on the periphery surface of the above middle rubber layer 2, a spiral reinforcing wire rod 4 is formed on the periphery surface of this 1st reinforcing layer 3, furthermore, a 2nd reinforcing layer 5 is formed, and subsequently, a rubber-made outer layer 6 is formed on the periphery surface of the above 2nd reinforcing layer 5. In addition, the rubber-made inner layer 1 is formed using a rubber composition containing a fatty acid amide. COPYRIGHT: (C)2006,JPO&NCIPI
