しい製造方法の管理や複雑な検査が必要となっている。Problems to be Solved by the Invention In the case of the first method or the second method in which a separate tube is joined after blow molding the tank body, the sealing performance depends on the durability and assembly state of parts such as O-rings and hoses. There is a problem that a variation occurs. For this reason, strict management of manufacturing methods and complicated inspections are required.

また、タンク本体とチューブをブロー成形によってす
べて一体に形成する第三の方法の場合、一回のブロー成
形によって造形する部分の容積が大きくなるため、金型
等のブロー成形のための設備が大型になるという不具合
がある。In the case of the third method in which the tank body and the tube are all formed integrally by blow molding, since the volume of the portion to be formed by one blow molding is large, equipment for blow molding such as a mold is large. There is a problem that becomes.
