第3実施例における燃料電池車10は、ラジエータファン310の構成が異なる点を除き、第1実施例と同様である。第3実施例のラジエータファン310は、搭載フレーム400に搭載された燃料電池110に対向部430が至るまで搭載フレーム400を変形させる大きさの荷重よりも小さな設定荷重Lsによって燃料電池110から離れる方向へ回転軸320が離脱する構造を備える点を除き、第1実施例と同様である。
第4実施例における燃料電池車10は、搭載フレーム400の構成が異なる点を除き、第1実施例と同様である。
第5実施例における燃料電池車10は、搭載フレーム400の対向部430の構成が異なる点を除き、第1実施例と同様である。
以上、本発明の実施の形態について説明したが、本発明はこうした実施の形態に何ら限定されるものではなく、本発明の趣旨を逸脱しない範囲内において様々な形態で実施し得ることは勿論である。例えば、第1実施例ないし第5実施例では、燃料電池110を搭載する搭載フレーム400について説明したが、燃料電池110に代えて電源回路120を搭載する搭載フレームや、燃料電池110に加え電源回路120を搭載する搭載フレームに、本発明を適用しても良い。また、第1実施例ないし第5実施例の少なくとも二つの実施例の構成を組み合わせても良い。
