ラーチユーブを提供しようとするものである。 The purpose of this invention is to be able to ground a product made mainly of synthetic resin without compromising its airtightness, to prevent electrification caused by friction when injecting gasoline, and to prevent fires. Furthermore, the upper part of the neck part can be formed by injection molding, which is suitable for molding complex shapes, and the filler tube body, which is to be connected to the neck part, can be formed by blow molding, which is suitable for molding even if it requires a bent part. The purpose of the present invention is to provide a filler tube for an automobile that can not only accurately bond even polyolefin resins that are difficult to bond with solvents but also have sufficient strength.

防止して火災を防止することができる。 As is clear from the above description, according to the present invention, a conductor is interposed between the joint of the neck portion of the synthetic resin filler tube and the joint of the filler tube body, and the melted portion of both joints is caused by heating of the conductor. are bonded under pressure, and the earth of the metal cylinder provided inside the filler tube is connected to the outside through the pressure bonded portion of the joint portion. Therefore, it is possible to provide grounding without impairing airtightness, and it is possible to prevent electrification due to friction during gasoline injection, thereby preventing fire.

ことができる。 Furthermore, as mentioned above, the filler tube body and the neck part are divided into upper and lower parts and molded separately, so the upper part of the neck part is formed by injection molding, which is suitable for molding complex shapes, and the filler tube body requires a bending part. It can also be formed by blow molding, which is suitable for that purpose.

とができる等の利点がある。 Furthermore, since the joints are melted and bonded under pressure as described above, it is possible to connect polyolefin resins that are difficult to bond with solvents with high accuracy, and equipment costs can be reduced. Since conductors such as the like are interposed, there are advantages such as sufficient strength can be obtained.
