A lens driving motor is provided to prevent deformation of a spring caused due to the rotation of a carrier and the change of a focus of a lens by restricting the carrier from being rotated through a support projection and a support groove formed at a housing and the carrier and hung to each other. A lens driving motor(100) is composed of a base(110); a housing(120) combined to the base and provided with an inlet hole formed on the upside; a yoke(130) fixed to the inner peripheral surface of the housing; a magnet(140) fixed to the inner peripheral surface of the yoke; a carrier(150) installed in the yoke to move up and down, inserted or projected through the inlet hole, and combined with a lens; a coil(160) fixed on the outer peripheral surface of the carrier with facing the magnet; ring-shaped springs(170) installed at the upper and lower sides of the yoke to return the carrier moved up by an interaction between the magnet and the coil, toward the original state; and a rotation preventing unit installed between the carrier and the housing to restrict the carrier from being rotated.
