Description
本発明における車両用灯具の実施形態を図面に基づき説明する。なお、図中の矢印UPは車両の上方向、矢印FRは車両の前方向、矢印INは車幅方向内側をそれぞれ示す。
次に、上記の実施形態の作用及び効果を説明する。
なお、上記実施形態では、圧力調整手段としての伸縮部50は、基部44寄りの波状部52が車両前後方向に凹凸を繰り返すように波状に折り曲げられているが、例えば、伸縮部50は、基部44寄りの部分が略筒状とされると共に車両上下方向に凹凸を繰り返すように波状に折り曲げられた蛇腹部とされる構成としてもよい。なお、灯室内の圧力変化を吸収可能な(伸縮部50等の)圧力調整手段には、例えば、灯室内の気圧が所定値を超えた場合にのみ灯室内の空気を灯室の外側へ排出する調整弁が形成されていてもよい。このような調整弁が形成されると更なる省スペース化を図ることができる。
