Abstract
An optical apparatus includes an optical element for shifting an incident position of a light beam on an image forming plane, a plurality of restricting portions for controlling an inclination position of the optical element with respect to an optical axis by respectively coming into abutment with end portions of the optical element and restricting positions of the respective end portions in a direction of the optical axis, and a driving part for driving the optical element to bring the optical element into abutment with the restricting portions. Each of the restricting portions has position restricting surfaces formed before and behind a corresponding one of the end portions of the optical element in the direction of the optical axis, and an inclination angle of the optical element relative to the optical axis is determined in such a way that the position of each of the end portions in the direction of the optical axis is restricted by the position restricting surfaces in a corresponding one of the restricting portions.
