<p><P>PROBLEM TO BE SOLVED: To inhibit fuel evaporative emission from flowing out as much as possible through a welded position of a resin fuel tank to a connector while appropriately ensuring their welding strength. <P>SOLUTION: The connector is a connector C for connecting a fluid flow path to the fuel tank T, and includes a body part 3 made from synthetic resin with high resistance to permeation of gas generated from fuel and an outer shell part 4 which is formed outside the body part 3 and which is made from synthetic resin capable of more easily permeating the gas than the body part 3 and capable of being welded to an outer face part Tb of the fuel tank T. The body part 3 includes a flange part 3d at an outer-periphery part, and the outer shell part 4 has a welding thickness part 4a covering a lower face 3e of the flange part 3d, diffracting from a top face side of the flange part 3d. The lower face 3e of the flange part 3d has an inclination with an outer-periphery end 3f side of the flange part 3d directed toward the upper side of the inclination. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
