<P>PROBLEM TO BE SOLVED: To provide a reflector for a vehicle and a reflex pin, which allow realization of light intensity equal to or higher than that of conventional such parts, simply by setting the inclination angles of first through third reflection surfaces. <P>SOLUTION: In a reflector for a vehicle, which includes a plurality of retro-reflection elements, each of the retro-reflection elements includes a first through third reflecting surfaces adjacently arranged to form a substantially cubic corner. The first reflecting surface is inclined at 35.264°+α1 with respect to a reference axis. The second reflecting face is inclined at 35.264°+α2 with respect to the reference axis and arranged at a position 120° rotated around the reference axis as center. The third reflecting surface is inclined at 35.264°+α3 and arranged at a position 120° rotated around the reference axis as center in a direction opposite to the second reflecting surface. The angles α1, α2, α3 are set so as to satisfy the relationship -α1=α2=α3 or -α1≈α2=α3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
