PROBLEM TO BE SOLVED: To enhance the adjustment operability of an opening angle adjustment mechanism of a dead angle auxiliary device.SOLUTION: A dead angle auxiliary device 20 includes a semi-transmissive mirror 21, and a mirror 22 which opposes a reflection face 21a of the semi-transmissive mirror 21 with an interval. An opening angle adjustment mechanism 70 which can adjust an opening angle θ between the reflection faces 21a, 22a is interposed between the reflection face 21a of the semi-transmissive mirror 21 and the reflection face 22a of the mirror 22. The opening angle adjustment mechanism 70 is constituted of a conversion mechanism 71. The conversion mechanism 71 converts an adjustment operation force for a rotation operation into a pressing force for pressing at least either of the reflection face 21a of the semi-transmissive mirror 21 and the reflection face 22a of the mirror 22 to an opening direction with a rotation center line RL extending to a direction along the reflection face 21a of the semi-transmissive mirror 21 as a center.SELECTED DRAWING: Figure 3
【課題】死角補助装置の開き角調整機構の調整操作性を高めること。【解決手段】死角補助装置20は、半透過ミラー21と、この半透過ミラー21の反射面21aに間隔を有して対面するミラー22とを含む。前記半透過ミラー21の反射面21aと、前記ミラー22の反射面22aとの間には、これらの各反射面21a,22a間の開き角θを調整可能な開き角調整機構70が介在している。この開き角調整機構70は、転換機構71によって構成されている。この転換機構71は、前記半透過ミラー21の反射面21aに沿う方向へ延びる回転中心線RLを中心として回転操作する調整操作力を、前記半透過ミラー21の反射面21aと前記ミラー22の反射面22aとの、少なくともいずれか一方を開き方向へ押圧する押圧力に転換する。【選択図】図3
