Claim:
A motor for driving lenses, the motor comprising: a case, wherein the case includes a base and a cover coupled to the base; a yoke fixed in the case; a magnet fixed in the yoke; a carrier equipped with lenses and installed in the magnet such that the carrier moves up and down within the magnet; a coil coupled with the carrier, wherein the coil cooperates with the magnet to move up and down the carrier; an upper spring unit including an inner section coupled to the carrier, an outer section supported by the case, and a connection section connecting the inner section to the outer section; and a lower spring unit including first and second springs separated from each other, wherein a lead wire of the coil is connected to the lower spring unit so that external power is supplied to the coil, and wherein the first spring and the second spring are disposed on a same horizontal plane, wherein each of the first and second springs comprises an inner section coupled to the carrier, an outer section disposed between the yoke and the base, a connection section connecting the inner section to the outer section, and a bending section connected to the outer section and bent downward, wherein each of the bending sections of the first and second springs is exposed by passing through the case, and each of the inner sections of the first and second springs is exposed out of the carrier such that the lead wire of the coil is connected to each of the inner sections of the first and second springs, wherein each of the outer sections of the first and second springs is disposed on an upper surface of the base and is contacted with the upper surface of the base, and wherein the bending section is disposed on a lateral surface of the base and is contacted with the lateral surface of the base.
