ABSTRACT:
A mirror assembly including a mirror and a mirror holder for holding the mirror from behind. The mirror has chamfers formed in the fore and back peripheral corners of the mirror. The foreside chamfer is so dimensioned that a light ray incident upon the mirror and reflected by a reflective film at its outer periphery (the border between it and the inward edge of the backside chamfer) toward the outer periphery side of the mirror is incident upon the foreside chamfer for preventing glare. The backside chamfer is so dimensioned that a light ray incident upon the mirror and reflected by its outer peripheral side face toward the reflective film side is incident upon the backside chamfer for preventing glare of the light ray incident upon the mirror, the portion directed toward the mirror's outer periphery side is incident upon either chamfer. Since these chamfers, formed by grinding, are opaque and ground glass-like, respectively, the light ray reflected outward thereby is soft and free of glare.
