a fixed portion comprising a base and a frame that is disposed on the base;
a movable portion, movable relative to the fixed portion, comprising a carrier for carrying an optical member with an incident optical axis, wherein the carrier comprises a body and a sidewall that extends along an edge of the body, wherein the carrier further comprises a first stopping portion and a second stopping portion protruding towards the fixed portion;
an electromagnetic driving assembly driving the movable portion to move relative to the fixed portion;
an elastic member, wherein the movable portion is movably connected to the fixed portion via the elastic member; and
a damping material connected to the fixed portion and the movable portion;
wherein the base has a recess facing the carrier;
wherein the carrier further comprises a protruding column protruding towards the fixed portion, and the recess is formed to contain the protruding column;
wherein the damping material contacts the protruding column and at least one surface of the recess.
