A motor for driving a lens is provided to prevent deformation of a spring fixed to a yoke by fixing the hexahedral yoke to a base and a housing to prevent rotation of the yoke. A base(110) and housing(120) are coupled with each other in a hexahedral shape and have a space inside. A yoke(130) has a horizontal plate(131) and a vertical plate(135). The horizontal plate is formed in a shape corresponding to that of the base and has an inlet hole at a center. The vertical plate is formed at a corner of the horizontal plate to be supported to a corner of the housing. A bobbin(140) is installed inside the yoke to be lifted, enters the inlet hole of the horizontal plate, and is coupled with a lens(200). A magnet(150) is fixed to the vertical plate of the yoke. A coil(160) is fixed to an outer surface of the bobbin and lifts the bobbin through interaction with the magnet. A spring(181,185) is installed in at least one of upper and lower parts of the yoke to return the lifted bobbin to an initial state.
