A lens driving motor is provided to prevent the rotation of carrier due to the contact between the side of yoke and the side of joint. A case(110) comprises an upper case(111) located at the upper side and a lower case(115) located at the lower side. The upper case and the lower case are combined. A yoke(120) is fixed inside the case. A magnet(140) is fixed to the yoke. A carrier(130) is installed inside the yoke to be ascended and descended. A coil(150) is fixed to the carrier. An inner circumference of springs(171,175) is fixed to the carrier. The outer circumference of the spring is fixed to the case side. The spring returns the risen carrier to the initial state. Anti-rotation units are prepared in the yoke and the carrier. The anti-rotation unit is comprised of a plurality of openings(128) and a protrusion(138) inserted into the opening. |
