ABSTRACT:
A lens driving device provided with a stator having a cylindrical shape, for generating a magnetic field therein; a rotor located within the stator and being rotation-driven by a magnetic field created by the stator; a lens holder located further inside the rotor, for holding a plurality of lenses with a small lens thereof being located at an arrangement end of the plurality of lenses; a converting mechanism for converting the direction of force of rotation driving of the rotor into direction along the optical axes of the lenses and transmitting the force in the direction thus converted to the lens holder; and a rotation stopper mechanism formed beside the small lens, for preventing the rotation of the lens holder.
