Abstract

PURPOSE:To obtain a large rotation angle and reduce the energy consumption due to unnecessary displacement by a method wherein the first and the second couplings which produce an angular moment at a movable part while being bent by dimensional strain generated by a piezoelectric substance. CONSTITUTION:Dimensional strain generated by elongation of a piezoelectric substance 3 is transmitted to a movable part 21 nearly along a board surface of the first coupling 41. As one end of the movable part 21 is supported by a fitting part 11 by the second coupling 51 which has elasticity, an angular moment is produced around an axis parallel to the board surface of the coupling 41. Displacement of the angle is produced at the movable part 21 by this angular moment. Accordingly, if an arm is fitted and fixed to the movable part 21, the angular displacement produced at the movable part 21 can be enlarged and reciprocal movement of the tip of the arm can be obtained. The ends of couplings 41 and 51 which are fixed to the movable part 21 move according to the fluctuation of the maovable part 21 and bending is occurred at the couplings 41 and 51. But as the thickness of the boards of the couplings is small the energy consumption can be small.
