Abstract: A hydrodynamic bearing device includes a stator and a rotor. The rotor forms a bearing clearance and a sealing part connected with the bearing clearance. A liquid-vapor interface is disposed in the sealing part together with the stator, and the bearing clearance is filled with a lubricating fluid. The stator and the rotor form a storage space connected with the sealing part to receive the lubricating fluid. The storage space has a region in which force applied to the liquid-vapor interface increases by a capillary phenomenon at a time that the lubricating fluid leaks to fill the bearing clearance.

Abstract: 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.
