<p>A vehicle reflector can include a plurality of retroreflection elements including a first reflection surface, a second reflection surface, and a third reflection surface which are adjacently disposed to form a corner portion of a substantially regular hexahedron. The first reflection surface can be inclined by 35.264°+angleα1 with respect to a reference axis. The second reflection surface can be inclined by 35.264°+angleα2 with respect to the reference axis and can be disposed at a position rotated by 120° about the reference axis from the first reflection surface. The third reflection surface can be inclined by 35.264°+angleα3 with respect to the reference axis and can be disposed at a position rotated by 120° in an opposite direction from the second reflection surface about the reference axis from the first reflection surface. The angleα1, angleα2 and angleα3 can be set to satisfy a relation of−α1=α2=α3 or−α1≈α2=α3.</p> |
