- ランプボディと該ランプボディの前端開口部に光軸に対しスラントして取り付けた透明なレンズカバーとにより画成されている灯室内に、複数の機能のランプを一体的に組み込んでなるコンビネーション型の車両用前照灯であって、
前記複数の機能のランプの間を仕切るインナーパネルであって、前記機能のランプを開口部から露出させて前記レンズカバーとランプボディの間に配置したインナーパネルと、
信号用の光を発する光源と、前記光源からの光を一端から入射して内面反射の繰り返しにより他端側に向かって導光し、かつ、該導光途中の光の一部を正面の発光面から出射させる導光体とを有してなる導光板を備え、
前記導光体は、前記レンズカバーとインナーパネルの間にレンズカバー内面に沿って配置され、その正面の発光面から出射される光を前記レンズカバーを透過して外部に出射する一方、その側面から漏れる光を前記インナーパネルで反射させ前記レンズカバーを透過して外部に出射することを特徴とする車両用前照灯。 - 上記導光体は、上記光源からの距離が光学的に遠くなるに従って徐々に断面積を小さく形成してなることを特徴とする請求項1に記載の車両用前照灯。
