Abstract
A driving apparatus comprising an optical element, a supporting block for supporting said optical element by contacting said optical element onto three supporting contact areas, a driving mechanism for practically connecting said supporting block to three driving contact areas and for moving said supporting block via the driving contact area, wherein a difference between an angle of each of the three supporting contact areas in a rotational direction around a rotation axis and an angle of each of the three driving contact areas corresponding with the three supporting contact areas is 10° or smaller, where the three supporting areas are substantially located on a first plane, and the rotational axis which is perpendicular to the first plane and passes through a barycenter of the three supporting contact areas.
