Abstract
An image shake correction apparatus includes a first fixing member; a movable member configured to correct the image shake, and configured to hold an optical element; a plurality of spherical members that are movable; a biasing member configured to apply a biasing force through the spherical member in the optical axis direction; a second fixing member that is disposed on the opposite side of the optical axis direction; and a plurality of damping members disposed in the second fixing member that suppresses vibration resulting from movement of the movable member. Either one of the first fixing member or the movable member includes a contact surface configured to make contact with the spherical member, and the maximum movable range of the contact surface overlaps with at least a portion of the installation region of the damping member in the optical axis direction.
