PURPOSE: A motor for driving a lens is provided to directly combine with a yoke on a base, to reduce the quantity of segments as an upper cap and a frame is not needed by segments being installed in a space where formed in a base and a yoke, to reduce prime costs by simplifying an assembly process, and to prevent damages on internal segments. CONSTITUTION: A motor for lens drive comprises: a base(110); a yoke which forms an internal space being combined with a base(120); a bobbin(130) which is arranged in the yoke; magnets(140) which is combined with the yoke; coils(150) which face magnets and which is combined to the outside of the bobbin; and springs(161, 165) which provides restitution to the bobbin being combined with the bobbin. The springs include an upper spring which is combined at the upper part of the bobbin; and a lower spring which is combined to the lower part of the bobbin and the yoke comprises an upper surface with an opening and an extended side in which a base is extended to the longitudinal direction from the upper surface. |
