<P>PROBLEM TO BE SOLVED: To provide a technology to improve connection strength and/or air-tightness between a connector pipe and a hose in a case of integrally molding the connector pipe to the hose by blow molding. Ž<P>SOLUTION: A reinforcing member 2 of fused flange face, surrounding the outer periphery of the hose 1 almost annularly, is insert-molded to the hose 1 by a blow molding technology. The reinforcing member 2 of fused flange face is provided with a fused flange face part 3 being flat normally, and one end of the connector pipe 5 is fused to the fused flange face part 3. The fused flange face part 3 and the hose 1 are formed of a through-hole, and the connector pipe 5 communicates with the hose 1 through the through-hole. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
