Abstract
A lens-holding frame comprises a frame body and a plurality of elastically deformable lens-holding arms. The arms are supported in a cantilever manner by the frame body and they circumscribe a circle having the same diameter as the lens. A positioning member is provided on the frame body along the circumference of the circle so that the positioning member abuts against the circumferential edge of the lens to define the lens holding position. Each arm is provided with a projection that penetrates inside the circle. The projection has a tapered surface, so that when the circumferential edge of the lens is engaged with the projections and the lens is pushed in toward the positioning member, the arms are elastically pushed open and the circumferential edge of the lens rides over the projections, whereby the lens is held.
