Abstract

PURPOSE:To aim at higher precision and smaller size by joining a stage with a nut housing containing an electric distortion element via a fine turning element and having a nut housing support the stage via a resilient member. CONSTITUTION:A feed screw 18 is turned by a rotary driving mechanism, and the turning motion is converted to a straight motion to transfer a nut housing 15 in the positive direction. Then the turning motion of the feed screw 18 is interrupted and the nut housing 15 is stopped still with respect to a base 11 before an electric distortion element 19 is driven to precisely position a resiliently supported stage 13 along a guide part 12. In such case if the axis X-X is displaced due to an error in manufacturing precision or assembly precision of the feed screw 18, the displacement can be absorbed by the resilient member and will not be transmitted to the stage 13.
