摘要： A tank joint part has a welding member welded to the outer surface of a fuel tank and a main body formed of a material of low fuel permeability and welded or otherwise joined to the welding member. The welding member is formed of modified polyethylene, which is easily weldable or otherwise joinable to the outer surface of the fuel tank and the main body, and in which very fine particles of a layered mineral are easily dispersible. The mineral is dispersed in layers oriented substantially at right angles to the direction of any possible permeation from the tank joint part. The tank joint part ensures a low fuel permeability and a high bonding strength.

摘要： An cylindrical convex portion of which opposite ends are open is integrally formed onto a fuel tank made of HDPE therewith so as to inwardly extend in the fuel tank to provide an opening thereon. A press-fit portion of a filler hose connecting pipe made of PA as a tubular member is press-fitted in the cylindrical convex portion to connecting the tubular member to the fuel tank. At least one continuous annular projection is provided on the outer peripheral surface of the press-fit portion of the tubular member so as to bite into the inner peripheral surface of the cylindrical convex portion to provide continuous circumferential contact. A face of the annular projection in direction axially of one end of tubular member is formed so as to extend outwardly and inclinedly with respect to the axial direction of the tubular member form one end toward the other end thereof.

摘要： A hose of low fuel permeability has a fuel permeability in a bent state with R50 not more than three times a fuel permeability in a straight state, R50 being a bent state where the hose has its longitudinal axis bent to form an arc having a diameter of 100 mm. Its low fuel permeability is achieved if the resin forming its inner wall layer has a melt viscosity falling within a certain range, which can be obtained by, for example, increasing the degree of polymerization of the resin, or grafting a specific side chain to the main chain in each molecule of the resin, or if the resin has a volume swelling degree falling within a certain range, which can be obtained by copolymerizing a monomer having fuel resistance, or blending a polymer having fuel resistance. The hose maintains its low fuel permeability even if it may be subjected to a large load of bending stress as when it is used to form a fluid conveying line.
摘要翻译：具有低燃料渗透性的软管在弯曲状态下具有燃料渗透性，其中R50在直线状态下不超过燃料渗透性的三倍，R50是弯曲状态，其中软管的纵轴弯曲形成直径为 100毫米。如果形成其内壁层的树脂的熔融粘度落在一定范围内，则可以获得低的燃料渗透性，这可以通过例如增加树脂的聚合度或将特定的侧链接枝到或者树脂的体积溶胀度落入一定范围内，这可以通过使具有耐燃料性的单体共聚，或者混合具有耐燃料性的聚合物而获得。软管保持其低的燃料渗透性，即使它可能受到大量的弯曲应力的负载，因为它用于形成流体输送线。
