Abstract
A vibration type driving apparatus includes a vibrating body having an electrical-mechanical energy converting element, a first elastic body and a second elastic body; and a moving body that moves relative to the vibrating body. The vibrating body has a third elastic body that includes a sliding surface. A resonance frequency in a mode where the non-sliding surface side of the vibrating body in the axial direction mainly vibrates with the third elastic body is adapted so as to fall out of a frequency range between a multiple of a maximum frequency of a driving signal applied to the electrical-mechanical energy converting element, and a multiple of a minimum frequency of the driving signal.
