Abstract
A support structure is provided wherein a fitting backlash is provided between a lens and a retaining frame to enable positioning of the lens while restraining degradation of optical performance even if the lens shifts. The lens has two opposed optical characteristic surfaces. A first one of the optical characteristic surfaces is formed of a spherical surface, while the other has a spherical portion that is annularly formed in a periphery thereof and that has the same center as the spherical surface of the first one of the optical characteristic surfaces. When abutted on an inner circumferential end of the retaining frame, the spherical portion is correctly aligned and supported on an optical axis of an optical system (see FIG. ).
