Abstract
In a vehicle periphery visual confirmation apparatus, between the vertical angle portion of a prism and the front end portion of a case A is interposed a light shield portion which shields light rays crossing substantially in the right and left direction in front of the prism . Even in case where light rays coming from the outside enter in front of the vertical angle portion of the prism and are going to cross in front of the prism , the light rays can be prevented by the light shield portion . This can prevent the overlapped reflection of a vision image resulting from the fact that the light rays crossing in front of the prism are reflected by the internal surfaces of the penetration window portions and enter the interior portion of the prism.
