RESIN MOLDED PRODUCT AND MANUFACTURING METHOD OF THE SAME
To provide a resin molded product having high pressure strength in an internal flow path.SOLUTION: A resin molded product, that is a hollow member having at least a first flow path and a second flow path that receive fluid pressure from the inside, comprises: a first molded part that has a first partition wall that separates the outside and an internal space of the resin molded product, and a second partition wall that separates the first flow path and the second flow path in the internal space; a second molded part that has a third partition wall that separates the outside and the internal space of the resin molded product, and a fourth partition wall that separates the first flow path and the second flow path in the internal space; and a third molded part that has an outer peripheral part that joins an end part of the first partition wall and an end part of the third partition wall, and an inner part that joins an end part of the second partition wall and an end part of the fourth partition wall so as to define the first flow path and the second flow path in the resin molded product. The first molded part and the second molded part have a first expansion partition wall and a second expansion partition wall extending from one of partition walls into the first flow path, and the third molded part has an extension portion that joins the first expansion partition wall and the second expansion partition wall.SELECTED DRAWING: Figure 2
【課題】内部の流路における高い圧力強度を有する樹脂成形品を提供する。【解決手段】樹脂成形品は、内部から流体圧力を受ける少なくとも第１流路及び第２流路を有する中空部材である樹脂成形品であって、樹脂成形品の外部と内部空間とを区分する第１隔壁と、内部空間において、第１流路と第２流路とを区分する第２隔壁と、を有する第１成形部と、樹脂成形品の外部と内部空間とを区分する第３隔壁と、内部空間において、第１流路と第２流路とを区分する第４隔壁と、を有する第２成形部と、第１隔壁の端部と第３隔壁の端部とを接合する外周部分と、樹脂成形品において第１流路及び第２流路を確定するように、第２隔壁の端部と第４隔壁の端部とを接合する内側部分と、を有する第３成形部と、を備え、第１成形部及び第２成形部は、いずれかの隔壁から第１流路内に延びる第１拡張隔壁及び第２拡張隔壁を有し、第３成形部は、第１拡張隔壁及び第２拡張隔壁を接合する拡張部分を有する。【選択図】図２
