<p><P>PROBLEM TO BE SOLVED: To provide a rubber hose with a metalpiece that is firmly and easily fixed without enlarging a hose diameter by folding back reinforcing code layers, capable of preventing the reinforcing code layers from loosening and displacing. <P>SOLUTION: A belt-like ply 8 is spirally provided and the reinforcing code layers 7a, 7b are provided for a hose main body 2. A bead 9 is formed at outside of the inner layer side reinforcing code layer 7a at an outer circumferential side of the mouthpiece 3 by winding a wire 11. The bead 9 is engaged with a projection 10 of an outer circumferential surface of the mouthpiece 3. The ply 8 is folded back while applying an appropriate tension force by hooking on the bead 9. Folding back at an end part of each layer is not required as the reinforcing code layers 7a, 7b are continued. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
