<p>An actuator for driving a driven member (11) which comprises a base (17), first and second driving members (1,2) each fixed to the base (17) and having one vibrating direction (5,6), a resultant motion mechanism (18) connected to the first and second driving members (1,2), combining their unidirectional vibrations and generating resultant vibration having circular orbit, a driving element (10) transmitting the resultant motion of the resultant motion mechanism (18) to the driven member (11), and means (12-16) for imparting excitation force to the first and second driving members (1,2).</p> |
