PROBLEM TO BE SOLVED: To provide a pipe joint for a resin tank having high impact resistance. SOLUTION: This pipe joint 1 for the resin tank has a pipe wall 10 formed by including an inner peripheral layer 30 composed of a fuel resistant resin and an outer peripheral layer 31 composed of polyethylene weldable to the resin tank. A specific gravity of the polyethylene is not more than 0.94. The outer peripheral layer 31 is arranged at least in a welding part to the resin tank and an impact force concentrating part 202 of the pipe wall 10. Even if impact is applied to the impact force concentrating part 202, the outer peripheral layer 31 only extends, and does not rupture. Thus, the pipe joint 1 for the resin tank has the high impact resistance. COPYRIGHT: (C)2004,JPO
