Abstract
【解決手段】光源20からの出射光を導光して前方へ向けて出射させる導光体30として、車幅方向に延びるサブ導光部32と水平面に沿って延びる板状のメイン導光部34とが上下方向に互いに隣接して配置された構成とする。そして、光源20からの出射光を、サブ導光部32の右端面32cから入射させて車幅方向に導光しながらメイン導光部34へ向けて出射させる構成とする。これによりメイン導光部34に入射する光をある程度均一な光とする。その上で、メイン導光部34に入射したサブ導光部32からの光を、その後端面34bで内面反射させてその前端面34aから前方へ向けて出射させる構成とする。これにより前端面34aから出射する光をさらに均一な光とする。
