生じる弾性体と、この弾性体に当接し該弾性体表
面の楕円運動の頂点との摩擦力によつて移動する
動体とを備えた超音波モータにおいて、 前記弾性体と前記動体とが対向接触する面の内
、少なくとも一方の面を、該表面の突起部の曲率
半径を大きくする耐摩耗性表面加工を施した平坦
面としたことを特徴とする超音波モータ。[Claims for Utility Model Registration] By the frictional force between an elastic body that is energized by ultrasonic vibrations of a piezoelectric body and generates traveling waves on its surface, and the apex of the elliptical motion of the surface of the elastic body that comes into contact with this elastic body. In an ultrasonic motor equipped with a moving moving body, at least one of the surfaces where the elastic body and the moving body come into contact with each other is subjected to a wear-resistant surface treatment that increases the radius of curvature of a protrusion on the surface. An ultrasonic motor characterized by having a flat surface.
