Abstract
An actuator which tilts and drives an object to be driven around an axis of rotation includes: a pair of supporting beams arranged to support the object to be driven from both sides thereof in a direction parallel to the axis of rotation; a pair of movable beams arranged to sandwich the object to be driven and the pair of supporting beams from both sides in a direction perpendicular to the axis of rotation; a drive source arranged to apply bending vibration to the movable frames; and a pair of connection parts arranged to connect the movable frames and end portions of the supporting beams by a multiple-beam structure, convert the bending vibration into torsional vibration, and transmit the torsional vibration to the supporting beams.
