Abstract
An optical-element supporting device arranged to support and set one or a plurality of optical elements in respective predetermined positions in an optical axis direction, includes ring frames mounted respectively on the plurality of optical elements and each having a plurality of projections protruding in the optical axis direction, and a pinching structure for pinching the ring frames being piled up in the optical axis direction (the pinching structure comprising, for example, a lens barrel member which accommodates the ring frames mounted on the optical elements and leaf springs mounted near an end part of the lens barrel member in the optical axis direction), wherein the projections of the ring frames and respective pinching positions of the pinching structure are axially aligned in parallel with the optical axis direction.
