    摘要： A vibration wave driving apparatus includes a vibration member in which an electro-mechanical energy conversion element is fixed to an elastic member, and a contact member pressed against a sliding part provided in the vibration member, so as to be kept in contact therewith. The vibration wave driving apparatus is configured to supply alternating signals in a predetermined driving frequency band to the electro-mechanical energy conversion element, thereby generating a predetermined natural vibration mode in the elastic member to drive the contact member. In the apparatus, the natural vibration mode is generated in the elastic member, a natural frequency of another vibration mode different from the natural vibration mode is detected, and a stiffness of the support member is altered if the natural frequency of the other vibration mode detected is included in the driving frequency band.
