<P>PROBLEM TO BE SOLVED: To provide a flexible synthetic resin hose which includes joint end portions for mounting a mouth member in both ends of a hose body, and in which a hard synthetic resin reinforcing wire spirally wound around a tube wall of the hose body is prevented from jumping out of a cut opening end faces of the joint end portions. <P>SOLUTION: On a tube wall 1 of a hose body A1 made of a soft polyvinyl chloride resin, a soft polyvinyl chloride resin hollow spiral projection wall 3 including an olefin based hard synthetic resin reinforcing wire 2 therein is provided integrally. In both end portions of the hose body A1, the reinforcing wire 2 is reduced in diameter, bent from a spiral direction to a hose length direction, and such a bent reinforcing wire part 2a is formed into joint end portions A2, A2 covered with a hollow bent projection wall part 3a continued to the hollow spiral projection wall 3. The end portion of the bent reinforcing wire part 2a is prevented from jumping out of an opening end face of the hollow bent projection wall part 3a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
