Abstract
Disclosed is a voice coil motor, the motor including a mover having a bobbin equipped with a lens and a coil block secured to an outer circumference of the bobbin; a stator having a magnet that is disposed in such a way as to face the coil block; elastic members coupled to a lower end of the bobbin and connected to both ends of the coil block; a base supporting the elastic members and the stator; and a cover can covering the mover, the stator and the base, with an opening being formed in the cover can to expose the lens therethrough, wherein each of the elastic members includes a terminal portion that extends between the cover can and a side surface of the base, the terminal portion including a short-circuit prevention portion so as to inhibit a short-circuit between the terminal portion and the cover can.
