ABSTRACT:
A joint for fuel tank is attached to an opening of a resin fuel tank. The joint includes a joint main body and a flanged junction. The flanged junction is connected to the joint main body and is weldable to a periphery of the opening of the fuel tank. The joint main body includes a semi-aromatic polyamide obtained by polymerization of source monomers containing an aromatic monomer component and an aliphatic monomer component. An amount of a terminal amino group of the semi-aromatic polyamide is greater than or equal to 40 μeq/g. The junction includes a modified polyolefin having: a density in a range of 0.930 to 0.950; and a melt flow rate as measured in accordance with JIS-K7210 in a range of 0.06 to 3.0 g/10 minutes.
