Abstract:
A vibrating type driving device comprising:a vibration member in which vibration is generated;a moving member press contactable with said vibration member and rotatable driven by vibration generated in said vibration member;an output shaft coupled to said moving member and rotated by rotation of said moving member;pressurizing means for press contacting said vibration member and said moving member to each other; anda plurality of bearings separately arranged in an axial direction and rotatably supporting said output shaft, each of said plurality of bearings being arranged so as to separately receive a reactive force of pressure applied by said pressurizing means, said reactive force acting in the same direction as the axial direction; andan elastic member functionally contactable with at least one of said plurality of bearings so as to distribute the reactive force among said plurality of bearings.
