PROBLEM TO BE SOLVED: To provide a rigidity reinforcing device for an automotive fuel tank which is designed to ensure robustness of the fuel tank in positive pressure and negative pressure states and prevent breakage phenomenon causing oil leak during collision.SOLUTION: A rigidity reinforcing device for an automotive fuel tank has an improved structure of a rigidity reinforcing member attached to the inside of the fuel tank made of a plastic material. The improved structure makes it possible to maintain rigidity in a positive pressure state of the fuel tank and in a state in which a negative pressure of an engine is exerted, and also makes it possible to induce breakage due to impact, such as a vehicle collision, thereby preventing rupture of a part of the fuel tank which is fused to upper and lower plates.SELECTED DRAWING: Figure 1
【課題】燃料タンクの正圧及び負圧状態での強健性を確保するとともに衝突事故時に漏油を引き起こす破損現象を防止するようにした自動車用燃料タンク剛性補強装置を提供する。【解決手段】プラスチック材の燃料タンクの内部に装着される剛性補強部材の構造を燃料タンクの正圧状態及びエンジンの負圧が作用する状態で剛性を維持することはもちろんのこと、車両衝突事故のような衝撃による破損を誘導することができ、燃料タンクの上下板と融着される部分の破裂を防止することができる構造に改善した自動車用燃料タンク剛性補強装置である。【選択図】 図1
