Abstract: A VCM actuator for a lens and driving the lens for focusing includes a fixed module, a mobile module and a spring module. The fixed module includes a case and the magnet module is disposed along the inner side of the case. The mobile module includes a lens holder and a coil looping the lens holder. The lens holder is movably disposed in the case and the coil is fastened to the lens holder positioning to the magnet module. The spring module abuts the fixed module and mobile module. The case has an opening and along the rim of each corner of the opening a magnet guiding tab is formed. The guiding tabs extend between the lens holder and coil and are positioned toward the gaps between the magnet module, and each magnet guiding tab has a backbone and two wing portions extending from the backbone.
