ABSTRACT:
An actuator100of the type employing a two-degree-of-freedom vibration system includes: a pair of first mass portions1, 11; a second mass portion2provided between the pair of first mass portions1, 11; a pair of supporting portions3, 3for supporting the pair of first mass portions1, 11and the second mass portion2; at least a pair of first elastic connecting portions4, 4which respectively connect the first mass portions1, 11to the supporting portions3, 3so that each of the first mass portions1, 11can rotate with respect to the supporting portions3, 3; and at least a pair of second elastic connecting portions5, 5which respectively connect the second mass portion2to the first mass portions1, 11so that the second mass portion2can rotate with respect to the first mass portions1, 11. Each of the first mass portions1, 11is driven by the application of an alternating voltage, causing the second mass portion2to rotate.
