Abstract
PURPOSE:To turn into the strong turning effort by dividing one piece of electrode if a piezo-vibrator into two, combining a driven substance with the end of a stator and driving the driven substance. CONSTITUTION:A stator of an ultrasonic driving gear holds the piezo-vibrators 3-4 such as a ceramic vibrator and others between one metal block 1 and the other metal block 2, and has the electrodes 5-6 between the metal block 1 and the piezo-vibrator 3 and between the piezo-vibrators 3-4. And, a bolt 7 passes through the center holes of the piezo-vibrators 3-4 and the electrodes 5-6, the screws 7(a)-7(b) of the bolt 7 are fitted into the screw holes 1(a)-2(a) provided to the metal blocks 1-2 and constitutes a stator 8. And, the electrode 6 provided between the piezo-vibrators 3 and 4 is divided into two, and a clearance 9 is provided between the electrodes 6(a) and 6(b). Accordingly, a driven substance can be driven by combining the driven substance with the end and side faces of the metal blocks 1-2 and sides.
