<P>PROBLEM TO BE SOLVED: To provide an inexpensive hose configured to substantially completely prevent fluid leakage, and to provide a manufacturing method thereof. <P>SOLUTION: The hose 100 includes, from the outside to the inside, an outer spiral wire 1, outer cloth 2, a film 3, an outer tube 4, a film 5, an inner tube 6, and an inner spiral wire 9. The cylindrical outer tube 4 and inner tube 6 are layered in a double form in the hose 100, thereby substantially completely preventing leakage of fluid flowing in the hose 100. The hose can be simplified in overall structure, and employs commercially available tubes for the outer tube 4 and the inner tube 6, thereby reducing the price. <P>COPYRIGHT: (C)2013,JPO&INPIT |
