To improve visibility by achieving the high brightness of the entire warning display portion uniformly, without increasing the number of light sources or current consumption.SOLUTION: A vehicular warning device is equipped with a light-guiding member 4 that has a light incident surface in which light irradiated from a light source is incident, a fore-and-aft direction reflection surface 45 that reflects the incident light backward, and a light emission surface. On a back side of the light emission surface, a warning display portion of a backward visually checking mirror is disposed. The fore-and-aft direction reflection surface 45 has a plurality of structure surfaces 45a aligned in both of a vertical direction and a lateral direction. The plurality of structure surfaces 45a is individually set in orientation so as to have reflected light turned to the warning display portion.SELECTED DRAWING: Figure 9
【課題】光源の数や消費電流を増やすことなく、警告表示部の全体を均一に高輝度化して視認性を向上させる。【解決手段】車両用警告装置は、光源から照射された光が入射する光入射面と、入射した光を後側へ向けて反射させる前後方向反射面45と、光出射面とを有する導光部材4を備えている。光出射面の後側には、後方視認用ミラーの警告表示部が配置されている。前後方向反射面45は、上下方向及び左右方向の両方向に並ぶ複数の構成面45aを有している。複数の構成面45aは、反射した光が警告表示部に向くように個別に向きが設定されている。【選択図】図9
