摘要： A vibration type driving apparatus, which is capable of increase of output torque and rotational speed without increasing the size of a vibration body, is described. The apparatus comprises a vibration body which generates vibration by supplying a driving signal to an electro-mechanical energy converting element and a contact body which contacts this vibration body and is moved by vibration received from the vibration body. The vibration body comprises a base portion having the electro-mechanical energy converting element and a plurality of vibration amplification portions for amplifying vibration generated at this base portion. Neighboring vibration amplification portions of the plurality of vibration amplification portions are connected at a position different from a connecting position of each vibration amplification portion with the base portion.

摘要： There is provided a foreign substance removing device which is capable of moving a foreign substance in a desired direction at a high removing efficiency. The foreign substance removing device removes a foreign substance on an object. A vibrator has first and second piezoelectric elements provided on the object. Power supplies applies alternating voltages to the respective first and second piezoelectric elements. A control circuit controls the alternating voltages applied by the power supplies. The control circuit changes the frequency of the alternating voltage and at the same time makes respective phases of the alternating voltages applied to the first and second piezoelectric elements different from each other, so as to concurrently generate a first standing wave and a second standing wave different in order.
