To provide a technology which can further improve the protection performance of a fuel system component without causing an increase of the number of part items and weight.SOLUTION: An extension part 34 having a protruding piece 34a is arranged at a protector 20, and when the protector 20 is attached to an internal combustion engine 1, the protruding piece 34a opposes a recess 60b in a position separating from the recess 60b of an existing fastening bolt 60 by a prescribed distance. By this constitution, when the protector 20 is deformed due to a collision to a radiator shroud 92 and the protector 20 of an intake manifold 14 accompanied by a collision of a vehicle, the protruding piece 34a of the extension part 34 of the protector 20 can abut on the inside of the recess 60b of the opposing fastening bolt 60. The protector 20 can be thereby favorably suppressed from being displaced to any direction including vertical and left-and-right directions with respect to the internal combustion engine 1, and a fuel system component 12 can be surely protected.SELECTED DRAWING: Figure 16 【課題】部品点数の増加や重量増加を招くことなく燃料系統部品の保護性能をより一層向上することが可能な技術を提供すること。【解決手段】プロテクタ２０に突片３４ａを有する延出部３４を設け、プロテクタ２０が内燃機関１に取り付けられた際に、当該突片３４ａが既存の締結ボルト６０の凹部６０ｂに対して所定距離離れた位置において当該凹部６０ｂに対向する構成とする。これにより、車両の正面衝突に伴うラジエータシュラウド９２やインテークマニホールド１４のプロテクタ２０への衝突に起因してプロテクタ２０が変形する際に、プロテクタ２０の延出部３４の突片３４ａを、対向する締結ボルト６０の凹部６０ｂ内に突き当てることができる。これにより、プロテクタ２０が内燃機関１に対する上下左右方向を含むあらゆる方向へズレることを良好に抑制し得て、確実に燃料系統部品１２の保護を図ることができる。【選択図】図１６
