動装置。[Claims for Utility Model Registration] (1) One or more piezoelectric vibrators are made of a long metal block that is long in length relative to its diameter and a short metal block that is short in length, with the long metal block A stator is constructed by sandwiching the short metal blocks with bolts having male threads at both ends in screw holes provided in the axial direction approximately at the center of each of the short metal blocks, and bearings are mounted on the metal blocks at both ends of the stator. , a shaft is rotatably supported by the bearing through an axial hole provided in the bolt;
An ultrasonic drive device characterized in that a rotor is fixed to one end of the shaft and brought into contact with an end surface of the stator, and the other end of the shaft is screwed. (2) The ultrasonic driving device according to claim 1, wherein at least one of the contact portions of the rotor or the stator is provided with a wear-resistant material.
