PROBLEM TO BE SOLVED: To prevent a cracking phenomenon from occurring and to maintain always a prescribed corrosion resistance high even if a buried member buried in a narrow part formed by pipes and brackets, and an anti-chipping and an anti-rust protection film layer laminated and formed on an anti-corrosion protection film layer are subject to a temperature difference caused by climate change such as winter season and summer season and the like.SOLUTION: A substantially triangular prismatic buried member 9 made of a synthetic resin such as polyethylene is buried and fitted to a narrow part 6 formed between a filler pipe 2 and a bracket 5 under a state in which an anti-corrosion protection film layer 8 of plating, or plating and cation coating is formed on surfaces of the filler pipe 2 and the bracket 5, synthetic resin powder of the same material as that of the buried member 9 is powder-coated on the anti-corrosion protection film layer 8 as well as the buried member 9 so as to laminate and form the anti-chipping and the anti-rust protection film layer 11.

    【課題】パイプ類及びブラケットによって形成された狭隘部に埋め立てた埋設部材と、耐腐食保護膜層上に積層形成された耐チッピング並びに耐発錆保護膜層とが、冬季や夏季などの気候変動による温度差を受けたとしても、亀裂現象を生じないようにして、常に所定の腐食耐性を高く保持する。【解決手段】フィラーパイプ2及びブラケット5の表面に、メッキ又はメッキ及びカチオン塗装からなる耐腐食保護膜層8を形成した状態で、フィラーパイプ2とブラケット5との間に形成される狭隘部6にポリエチレンなどの合成樹脂からなる略三角柱状のの埋設部材9を埋設嵌合し、埋設部材9を含めて耐腐食保護膜層8上に、埋設部材9と同材質からなる合成樹脂粉体をパウダー塗装することによって耐チッピング並びに耐発錆保護膜層11を積層形成した。【選択図】図6
