次に、本実施形態に係るホールプラグの作用及び効果について説明する。
図1に示すように、本実施形態のホールプラグ10では、フラップ弁58はコイルスプリング66の付勢力とフラップ弁58の自重とによって、排水口60を閉じる方向へ付勢されており、排水口60は閉じている。この結果、車外から排ガスや水等が浸入するのを防止できる。
以上に於いては、本発明を特定の実施形態について詳細に説明したが、本発明は上記第1実施形態に限定されるものではなく、本発明の範囲内にて他の種々の実施形態が可能であることは当業者にとって明らかである。例えば、コイルスプリング66に代えて、図9に示す第2実施形態にように、フラップ弁58の連結部58Bから、弾性変形可能な板ばね形状の凸部70(付勢手段)を一体的に形成し、この凸部70を付勢手段とした構成としてもよい。この構成では、凸部70が弁収納部54の上壁部54Aの下面を押圧することで、フラップ弁58が排水口60を閉じるようになっている。
