CONSTITUTION: A mover(100) comprises a coil block(190) arranged in the outer circumference of a bobbin(150) in a cylindrical shape and the bobbin including a hollow hole for fixing a lens. A stator(200) comprises a magnet(250) facing with the coil block and a yoke(210) fixing the magnet. A case(300) comprises an upper case(320) combined with a lower case(310) and the lower case including the bobbin. An elastic member(400) flexibly supports the upper end of the bobbin and lower end facing the upper end. A coil block fixing part(153) is arranged in the outer circumference of the bobbin. |
