    Abstract: An embodiment comprises: a housing comprising a first protrusion and a second protrusion on the lower part; a bobbin disposed inside the housing; a first coil disposed on the bobbin; a magnet disposed in the housing and opposite from the first coil; a second coil disposed on the outer lateral surface of the housing; an upper elastic member coupled to the upper part of the bobbin; and a lower elastic member coupled to the lower part of the bobbin. The lower elastic member comprises a first spring, a second spring, a third spring and a fourth spring which are disposed away from each other. One part of the second coil is wound at least once around the first protrusion and is connected to the first spring. The other part of the second coil is wound at least once around the second protrusion and is connected to the second spring.
