PROBLEM TO BE SOLVED: To enable inclination regulation in a lens unit for an image side regulation center by arranging a regulation center in inclination regulation of lenses on an image side. SOLUTION: A lens regulation mechanism comprises the lens unit for holding a lens group, a lens support for supporting the lens unit on the image side of the lens group, and a base for supporting the lens support on the image side of the lens group. The lens support has a projection for slidably supporting the lens unit by being projected toward an object side of the lens group. A face in contact with the lens unit in the projection is formed on a spherical face at the center of a prescribed position of the image side of the lens group. COPYRIGHT: (C)2008,JPO&INPIT
