板ばねの変位部の途中には、前記本体に向かつて
変位部から所定の傾斜角で立上がつた入力部が連
設され、その入力部の自由端には、その自由端を
前記変位部の固定端を支点として変位させること
により変位部全体をその固定端を支点として変形
させる積層型圧電素子が取付けられると共に、こ
の積層型圧電素子の伸縮方向と前記入力部の立上
がり方向が略一致するように当該圧電素子が配設
されたことを特徴とする変位機構。 A leaf spring is cantilever-supported on the main body, and an input part is connected to the middle of the displacement part of the leaf spring protruding from the main body, rising up from the displacement part at a predetermined angle toward the main body. A laminated piezoelectric element is attached to the free end of the section, and the laminated piezoelectric element deforms the entire displacement section using the fixed end of the displacement section as a fulcrum by displacing the free end using the fixed end of the displacement section as a fulcrum. A displacement mechanism characterized in that the piezoelectric element is arranged so that the expansion and contraction direction of the input section substantially coincides with the rising direction of the input section.
