Abstract: A microactuator including a base frame; and a moving plate having both ends supported by a plurality of elastic support portions inside the base frame, the moving plate having a first side on which a reflective mirror for changing a light path is disposed. At least one first rib is disposed along an edge of a second side of the moving plate, which is the reverse side of the first side of the moving plate, and a second rib is disposed in the center of the second side of the moving plate and correspondingly encloses a permanent magnet. Also, a portion of the second side of the moving plate, except for the first and second ribs, is removed to a predetermined depth to reduce the weight of the entire moving plate and to define the first and second ribs.
