Abstract:
A driving apparatus has a vibration plate, a vibrator having a piezoelectric element that excites vibration of the vibration plate, and first and second contact parts, and a friction member being in contact with the contact parts. The vibrator and the friction member relatively move with respect to each other, and the contact parts are provided at positions with and interpose an odd number of antinodal lines of vibration generated in a first direction of the vibrator along with excitation, and provided at positions with and interpose an odd number of nodal lines of vibration generated in a second direction of the vibrator along with excitation.
