To provide a device by which a viewer can visually recognize an outside view of a dead angle area blocked by obstacles, and which can suppress deterioration of visibility due to a light shielding part.SOLUTION: An ambient light guide optical device comprises: a transparent reflection part 12; a reflection part 14 which is located on an obstacle side of the transparent reflection part with a predetermined space therebetween; and a light shielding part 18 which is provided on a side of the transparent reflection part opposite to the reflection part, and blocks outside light that is incident on the transparent reflection part from the opposite side and is reflected. The light shielding part comprises a plurality of light shielding plates 16, and the plurality of light shielding plates are located with a space therebetween in a vertical direction so that a plate surface thereof becomes horizontal to a viewer positioned on the side of the transparent reflection part opposite to the reflection part. The transparent reflection part is tabular, and a plate surface thereof is parallel to a reflection surface of the reflection part and is inclined at a prescribed angle θ1 with respect to a vertical axis Y facing the viewer.SELECTED DRAWING: Figure 3

    【課題】障害物よって遮られた死角領域の外景を視認者が視認できるようにした装置において、遮光部により視認性が低下するのを抑制する。【解決手段】外景導光光学装置は、透反射部12と、透反射部の障害物側に所定の間隔を開けて配置された反射部14と、透反射部の反射部とは反対側に設けられ、その反対側から透反射部に入射して反射された外光を遮断する遮光部18とを備える。遮光部は、複数の遮光板16を備え、複数の遮光板は、透反射部の反射部とは反対側に位置する視認者に対し板面が水平となるよう、垂直方向に間隔を開けて配置され、透反射部は、板状で、板面が反射部の反射面と平行となり、かつ、板面が視認者に対向する垂直軸Yに対して所定角度θ1で傾斜している。【選択図】図3
