Abstract
A correcting optical device according to an aspect of the present invention in which, when image shake is not corrected, a restricting member is caused to engage an engaging portion, to restrict translational movement of a movable member, and in which, when the image shake is corrected, the restricting member is caused to disengage the engaging portion, to cause the movable member to be in a state capable of the translational movement, the restricting member being provided at the rotary member, the engaging portion being provided at the movable member. A driving unit drives the movable member in a direction in which the movable member moves translationally with respect to a fixed member in a plane perpendicular to an optical axis of a correcting lens, so that the correcting lens corrects the image shake, and drives the rotary member in a direction in which the rotary member rotates around the optical axis.
