Vibration-wave motor

Abstract

PURPOSE: To prevent partial friction, and to improve efficiency by dividing a slider into certain sections and separately making each section follow up to the sliding surface of a diaphragm. CONSTITUTION: A hemispherical contact member 7 is divided into some sections, and a plurality of the contact members 7 are mounted separately to a support plate 9 through an elastic body 8. The support plate 9 is fitted to a moving body through leaf springs 4. Even when the slider is given pushing force F by the leaf springs 4, each contact member 7 independently follows up to the warpage of a diaphragm 1, thus uniformly keeping surface pressure at all times.
