摘要： A camera module includes a carrier configured to move in an optical axis direction, a frame and a lens holder disposed in the carrier in the optical axis direction and configured to move together with the carrier in the optical axis direction, a first ball member disposed between the carrier and the frame, a second ball member disposed between the frame and the lens holder, and a third ball member disposed between the carrier and the lens holder. The frame and the lens holder are configured to move together in a first axis direction perpendicular to the optical axis direction. The lens holder is configured to move relatively with respect to the frame in a second axis direction perpendicular to the first axis direction, and the third ball member has more contact points with the carrier than the first ball member.

摘要： A camera module includes a lens barrel, a housing, a shield cover, and a buffer member. The lens barrel incudes a flange portion extending in a direction intersecting an optical axis. The housing is configured to accommodate the lens barrel and has a step portion configured to face a lower portion of the flange portion. The shield cover is coupled to the housing and configured to cover an upper edge of the lens barrel. The buffer member is configured to couple to a groove of the flange portion and protrude in opposing directions from the flange portion to selectively contact the shield cover and the step portion.
