To provide a dead angle auxiliary device capable of suppressing a difference in luminosity.SOLUTION: In a dead angle auxiliary device comprising a transflective mirror 111 and a mirror 112, light progresses in a prescribed direction by being repeatedly reflected and a maximum of three times of reciprocation is allowed. A reflection plane of the transflective mirror 111 can be divided into first to third regions respectively corresponding to first to third emission lights each, in accordance with first to third emission lights Lout1 to Lout3 respectively with zero, one time and two times of reflections on the transflective mirror. Further, a fourth emission light Lout4 is directly emitted without being transmitted through the transflective mirror 111, and since a reflection rate of the reflection plane of the transflective mirror 111 switches at a border spot CK of the second region and the third region, the reflection plane is divided into reflection rate A and B (A>B) regions, and the reflection rates A and B are set so that each of the light intensities of the second, third and fourth emission lights Lout2 to Lout 4 respectively are the same.SELECTED DRAWING: Figure 5

    【課題】明るさの差を抑制することができる死角補助装置を提供すること。【解決手段】死角補助装置は、半透過ミラー111と、ミラー112を備え、反射を繰り返して所定方向に光が進行し、最大で3往復が可能であり、半透過ミラーでの反射が零回、1回、2回である第1〜第3の各出射光Lout1〜Lout3に対応して、半透過ミラー111の反射面は、第1〜第3の各出射光に対応する第1〜第3の各領域に区分することができ、第4の出射光Lout4は、半透過ミラー111を透過されずに直接的に出射され、半透過ミラー111の反射面の反射率が、第2の領域と第3の領域との境界の箇所CKにて切り替わることで、反射率A、B(A>B)の領域に区分され、かつ、第2、第3、第4の各出射光Lout2〜Lout4の各光強度が同じとなるように、反射率A、Bが設定されている。【選択図】図5
