  • Vibration wave driving apparatus
    Patent number: 6819029
    Abstract: A vibration wave driving apparatus for obtaining driving force in 3D directions comprises a vibration member having a shape that is line-symmetrical with respect to two orthogonal axes, electro-mechanical energy conversion elements which can selectively excite in the vibration member three different types of bending vibrations, which each displace in a direction perpendicular to the two axes, and a driven member which is brought into contact with driving portions of the vibration member and driven by vibration excited in the vibration member.
    Type: Grant
