図1では、本実施形態に係る自動車用フード構造が適用された自動車用フード1を備える車両2が示されている。自動車用フード1は、図示しないエンジンルームを車両上方から覆うように車両前部に配置されている。自動車用フード1は、後述するヒンジ部3を介して車両本体に開閉可能に取り付けられている。すなわち、自動車用フード1はヒンジ部3のヒンジ軸回りに回転移動することでエンジンルームを開閉するように構成されている。
図7および図8を参照すると、本発明の第2実施形態に係る自動車用フード構造の構成は、以下の点で第1実施形態と異なる。第2実施形態のその他の構成は第1実施形態と同様であり、第1実施形態と同一ないし同様の要素には同一の符号を付している。
図11および図12を参照すると、本発明の第3実施形態に係る自動車用フード構造の構成は、以下の点で第2実施形態と異なる。第3実施形態のその他の構成は第2実施形態と同様であり、第2実施形態と同一ないし同様の要素には同一の符号を付している。
図13および図14を参照すると、本発明の第4実施形態に係る自動車用フード構造の構成は、以下の点で第2実施形態と異なる。第4実施形態のその他の構成は第2実施形態と同様であり、第2実施形態と同一ないし同様の要素には同一の符号を付している。
図15および図16を参照すると、本発明の第5実施形態に係る自動車用フード構造の構成は、以下の点で第2実施形態と異なる。第5実施形態のその他の構成は第2実施形態と同様であり、第2実施形態と同一ないし同様の要素には同一の符号を付している。
図17および図18を参照すると、本発明の第6実施形態に係る自動車用フード構造の構成は、以下の点で第1実施形態と異なる。第6実施形態のその他の構成は第1実施形態と同様であり、第1実施形態と同一ないし同様の要素には同一の符号を付している。
