Abstract
A vibrating type driving device is constructed by a vibration member in which a vibration is excited, a moving member which is come into contact with the vibration member and is rotated, an output shaft which is coupled to the moving member and is rotated, pressurizing means for making the vibration member and the moving member come into pressure contact with each other, and a plurality of bearings which are separately arranged in an axial direction for rotatably supporting the output shaft, wherein the plurality of bearings are arranged so as to separately receive a reactive force of pressure applied by the pressurizing means.
