摘要： The present invention relates to a vibration wave driving apparatus including 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 ratio 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.

摘要： A vibration wave driving element includes a vibration element and a moving element. The vibration element includes a member joined with an electro-mechanical energy conversion element. The moving element is in contact with a surface of the vibration element. The vibration element is in contact with the moving element through the surface opposite to a surface with which the electro-mechanical energy conversion element is joined, and a projection portion inside the moving element is formed on the surface of the vibration element that is in contact with the moving element. When a frequency of alternating signal applied to the electro-mechanical energy conversion element is varied, a ratio of vibration displacements in the same direction, each of which is generated on one of both ends of the vibration element, is varied.
