Abstract
At the time of crimping and fixing a plastic lens on a lens barrel, productivity is improved by achieving an accurate alignment and a reliable crimping. Fixed protrusions are arranged on an outer peripheral portion of the lens at intervals capable of providing three-point support, and a fixed protrusion is arranged on a line connecting the fixed protrusion and the center of the lens, a reference hole corresponding to one of the fixed protrusions includes an opening having substantially the same size as that fixed protrusion, and the other fixed protrusions have substantially the same size and fit in loosely fitting holes. The loosely fitting holes corresponding to the fixed protrusions include larger openings than the fixed protrusions and an elongated hole corresponding to another fixed protrusion is provided in such a manner as to be elongated along a direction of the reference hole.
