  • CAMERA MODULE
    Publication number: 20220103725
    Abstract: A camera module includes: a housing; a lens module configured to move in an optical axis direction in the housing; a first magnetic member disposed in the lens module; and a second magnetic member disposed to oppose the first magnetic member in the housing. The lens module is attached to one surface of the housing by magnetic attraction force arising between the first magnetic member and the second magnetic member. The lens module is supported at three points by three ball members disposed between the lens module and the housing. The first magnetic member is disposed in the lens module such that the first magnetic member is disposed in a triangle formed by virtual lines connecting the three ball members to each other.
