<p>An actuator comprises a piezoelectric element (32), one end face of the piezoelectric element (32) in a displacement direction being supported by a fixing member (38), a block shaped driving member (34) attached to the other end face of the piezoelectric element (32) in the displacement direction, and a driven member (30) frictionally engaged with at least one end face of the driving member (34) in a direction orthogonal to the displacement direction, the driven member (30) being extended along the displacement direction. The actuator is suitable for installation in a digital camera or a portable telephone to drive a lens (18).</p> |
