Abstract
An actuator for operating a desired driven member, including a laminar transverse-effect type piezoelectric driver having laminated piezoelectric elements which are displaced upon application of a voltage thereto in the direction of lamination. The actuator has a frame for supporting the piezoelectric driver at one of opposite ends thereof in a direction of displacement perpendicular to the direction of lamination. A transmission mechanism is disposed at the other end of the driver, for transmitting a displacement of the driver to the driven member. A longitudinal-effect type piezoelectric driver whose displacement in the direction of lamination is used to drive the driven member may be used in place of the transverse-effect type, together with an elastic member provided to bias the driven member when the driven member is moved to the operated position.
