Disclosed is an attitude controller (1) provided with: a plurality of elastic parts which are arranged on a reference surface (5a), extend in the direction of the normal to the reference surface (5a), and exhibit an elastic force in the direction of the normal in response to an applied voltage. The attitude controller (1) further comprises: a plurality of electromechanical conversion elements (6) which extend and contract in the direction of the normal when an equal voltage is applied to the plurality of elastic parts, and bend when different voltages are applied to the plurality of elastic parts; a plurality of friction members (7) respectively provided at the top sections of the electromechanical conversion elements (6); and a movable member (8) provided with one friction surface supported by the plurality of friction members (7). When some of the electromechanical conversion elements (6) are extended more than other electromechanical conversion elements (6) and are bent while supporting the movable member (8), the other electromechanical conversion elements (6) are extended and the inclined electromechanical conversion elements (6) are contracted, in order to transfer the movable member (8) among the friction members (7) and to move or rotate the movable member (8) parallel to the reference surface (5a). |
