PROBLEM TO BE SOLVED: To suppress generation of a positional deviation in an oscillation type driving apparatus due to an external force between an oscillator and a driver at the time of stopping driving.SOLUTION: An oscillation type driving apparatus 1 comprises a rotor unit 3 and a stator unit 2, and rotates the rotor unit 3 by oscillating oscillator units 5a and 5b included by the stator unit 2. The stator unit 2 includes: a holding base 18 in which deviation and a rotation deviation in a direction crossing to a thrust direction are regulated; and a holding member 16 that holds the oscillator units 5a and 5b, of which the rotation deviation to the holding base 18 is regulated, and the deviation is permitted in an X direction crossing to the thrust direction. A concave and convex part 23e is arranged in the rotor unit 3, and a projection part 16e is arranged in the holding member 16. The rotor unit 3 is set to a rotation regulation state by deviating the holding member 16 in the X direction with a driving force of the oscillator units 5a and 5b and engaging the concave and convex part 23e and the projection part 16e.SELECTED DRAWING: Figure 2 |
