Abstract
A piezoelectric motor comprising: a piezoelectric vibrator () having a surface comprising a localized non-planar shaped first surface region thereon which first surface region has a shape different from the shape of the surface on which it is located; and a friction nub () formed with a second surface region that is substantially a negative relief of the first surface region, which first and second regions are bonded together. Preferably the friction nub () is detachably mounted to the vibrator () via a boss () waving a protuberance () of conical shape. Alternatively the friction nub () has a protuberance () which is form-fitted to a recess () in the vibrator () or boss (), respectively. First and second surface regions can also be threading surfaces.
