しい。As a countermeasure, a resin component such as a pipe fitting mounted on an opening of a resin fuel tank is made of a resin having a barrier property for preventing fuel permeation, similarly to the resin material constituting the fuel tank. Although it is conceivable that the resin component is formed of a material (hereinafter simply referred to as a barrier material), a resin component formed only of the barrier material cannot be directly joined to the fuel tank. For this reason, it is also conceivable to join via a packing having an excellent permeation prevention function.However, unlike prevention of leakage from a mere gap, correspondence to a press contact portion, etc.
Prevention of fuel permeation is not easy, the structure becomes complicated, and the number of parts increases. Therefore, it is desirable that the resin component mounted on the resin fuel tank has a sufficient barrier property, and that the resin component is directly joined to the resin fuel tank without using a packing or the like.
