Abstract
An actuator device comprises an actuator element which has a shortest length when no electric voltage is applied and which is increased in length as an electric voltage applied thereto becomes higher, a displacement extracting part,, and a converter mechanism for carrying out conversion of converting the change in length of the actuator element,into the displacement of the displacement extracting part,. The converter mechanism comprises holders,and,and a transmission member,and carries out the conversion so that the displacement of the displacement extracting part,is decreased as the length of the actuator element,is increased. The converter mechanism carries out the conversion so that the displacement of the displacement extracting part,becomes maximum when the actuator element,has the shortest length.
