Abstract
An optical system driving apparatus includes a holding member holding an optical element and having first and second surfaces facing in opposite directions, and a carriage having first and second surfaces which contact the surfaces of the holding member and slidably clamp the surfaces of the holding member. At least one of a slidable contact surface portion of the first surface of the holding member which corresponds to the first surface of the carriage and a slidable contact surface portion of the first surface of the carriage which corresponds to the first surface of the holding member is formed into an at least partly spherical shape having a center coinciding with an optical center of the optical element, and the other portion guides the holding member to move in a circumferential direction of the spherical slidable contact surface portion. Further, at least one of a slidable contact surface portion of the second surface of the holding member which corresponds to the second surface of the carriage and a slidable contact surface portion of the second surface of the carriage which corresponds to the second surface of the holding member is formed into an at least partly spherical shape having a center coinciding with the optical center, and the other portion guides the holding member to move in a circumferential direction of the spherical slidable contact surface portion.
