Claim 16:
17. A lens driving device, comprising:
a base;
a housing disposed on the base;
a bobbin disposed in the housing;
a first coil disposed on the bobbin;
a magnet disposed on the housing;
a second coil disposed on the base;
an upper elastic member connecting the housing and the bobbin; and
a lateral elastic member electrically connected with the upper elastic member,
wherein the first coil is disposed on an outer peripheral surface of the bobbin,
wherein the bobbin comprises a flange unit protruding more than the first coil,
wherein the housing comprises a mounting unit overlapped with the flange unit of the bobbin in an optical axis direction,
wherein a downward movement of the bobbin is limited by the flange unit and the mounting unit,
wherein the upper elastic member comprises an inner portion coupled with the bobbin, an outer portion coupled with the housing, and a connection portion connecting the inner portion and the outer portion,
wherein the inner portion of the upper elastic member comprises first and second protrusions,
