<p>An actuator comprises a yoke (120) having a receiving space therein; a bobbin (141) disposed in the yoke and having a cavity (142); a coil (151) wound on a circumference of the bobbin and generating a magnetic force; a fixed core (161) fixedly disposed at one inner side of the bobbin; a movable core (171) disposed at another inner side of the bobbin; and a separating portion (145) formed of a non-metallic material, and interposed between the yoke and the movable core for separation therebetween. When a magnetic force is generated from the coil, the movable core is rapidly moved to the fixed core. Furthermore, a metallic collision between the yoke and the movable core is prevented thus to prevent noise and deformation.</p> |
