Abstract
A reflector for a vehicle can include a plurality of retroreflective elements configured to retroreflect incident light incident parallel to a horizontally-arranged reference axis, obliquely upward at a prescribed angle with respect to the reference axis. The plurality of retroreflective elements can each include: a first reflection surface inclined at an angle ANGto the reference axis; a second reflection surface inclined at an angle ANGto the reference axis, and formed in a position reached after the second reflection surface is rotated from the first reflection surface through an angle ROTaround the reference axis as a center; and a third reflection surface inclined at an angle ANGto the reference axis and formed in a position reached after the third reflection surface is rotated from the first reflection surface through an angle ROTaround the reference axis as a center in a direction opposite to the second reflection surface, the first to third reflection surfaces arranged so as to form corners of a substantial cube, wherein a condition of following expressions is satisfied: ANGANG; ANGANG; and ROTROT120 degrees.
