PROBLEM TO BE SOLVED: To provide a dead angle auxiliary device capable of improving visibility, by further easily reflecting an image of a dead angle area continuously with an image directly visually observed by a visual observer.SOLUTION: A dead angle auxiliary device 100 reflects an image of a dead angle area intercepted by an obstacle, and comprises a pair of mirrors 110 arranged so as to mutually oppose a semi-transmissive plane mirror 111 provided on the visual observer side, for making image-expressing light L incident and transmitting a part of the light L while reflecting a part of the light L and a plane mirror 112 for reflecting the light L to the semi-transmissive plane mirror 111. The plane mirror 112 includes a transmission reflection part 112a for transmitting a part of light while reflecting a part of the light to an incidence side end part E12. |
