ABSTRACT:
The present invention relates to a vibration wave driving apparatus includes a vibration element having an electro-mechanical energy conversion element that is disposed between a first elastic member and a second elastic member, characterized in that the vibration element can have a plurality of vibration modes which are different in relative displacement ration between respective ends of the vibration element. Specifically, a third elastic member is disposed between the first elastic member and the second elastic member, and the vibration element is allowed to have two portions which are different in dynamic stiffness from each other and are arranged in the axial direction thereof with the third elastic member interposed therebetween. According to this structure, the length of the vibration wave driving apparatus in the axial direction can be reduced and internal loss of vibration energy can be suppressed to be small.
