摘要：<P>PROBLEM TO BE SOLVED: To provide a drive unit which can obtain a relatively-large displacement amount by using a passive element which generates a relatively-small displacement amount of ER gel, or the like. <P>SOLUTION: A plurality of elements 11A, 11B which contract in directions parallel with electric fields when the electric fields are applied, and in directions different from the directions parallel with the electric fields are used in an actuator. A movable part 3 is supported in a prescribed direction so as to advance and retreat and is moved by the deformation of the elements caused by the application of the electric fields and the removal of the electric fields. The electric fields applied to the elements are generated by a plurality of electrodes 12A, 12B which are arranged so as to sandwich the elements, and a power supply 6 which feeds DC power to the electrodes. A control part 7 controls power fed to the electrodes 12 from the power supply 6 so that the electric fields are generated intermittently at prescribed cycles. <P>COPYRIGHT: (C)2010,JPO&INPIT
