A camera is provided. The camera includes a lens assembly aligned along an optical axis, an auto focus (AF) carrier for moving along the optical axis together with the lens assembly, and a housing for accommodating the AF carrier, a yoke may be fixed to a first outer surface of side surfaces of the AF carrier, the yoke includes a first portion having a first length in the optical axis direction and two protrusions which protrude toward the housing from both ends of a first portion, a first magnetic body, a magnet and a second magnetic body may be fixed in order in a direction parallel to the optical axis in a first inner surface facing the first outer surface of the AF carrier among the side surfaces of the housing, the magnet may have a first pole on a surface contacting the first magnetic body, and a second pole opposite to the first pole on a surface contacting the second magnetic body, and a second protrusion may face the second magnetic body while a first protrusion of the two protrusions of the yoke faces the first magnetic body.
