LENS DRIVING APPARATUS, CAMERA MODULE, AND OPTICAL DEVICE

Abstract: a lens driving device, includes a first housing, a bobbin, a second housing, first and second blades, a board; a first coil, a second coil, a third coil, a fourth coil; a first magnet facing the first coil; a second magnet facing the second coil; a third magnet facing the third coil; and a fourth magnet configured to adjust an area of a hole defined by the first and second blades. a length of an outer lateral surface of the second magnet facing the second coil in a direction of a y-axis perpendicular to an optical axis is greater than a length of an outer lateral surface of the fourth magnet facing the fourth coil in the direction of the y-axis. a shortest distance between the optical axis and the fourth magnet is shorter than a shortest distance between the optical axis and the second magnet.
