A vibrating body is vibrationally driven by the expansion and contraction movement of the piezoelectric element to thereby produce standing waves. A moving body is frictionally driven by the standing waves of the vibrating body. Power transmission projections apply a frictional force to the moving body to thereby frictionally drive the moving body in accordance with the standing waves. The power transmission projections are disposed only every preselected number of wavelengths at intermediate positions between loops and nodes of the standing waves, the preselected number being a natural number.

Second projections are provided at each intermediate position between the first projections near all of the boundaries of the electrode patterns other than the boundaries near which the first projections are provided for adjusting the vibrating conditions of the vibrating member. The second projections have a different height from the first projection and do not frictionally drive the moving member.

The second polarized portion of the first piezoelectric body is aligned in the preselected direction with the first polarized portion of the second piezoelectric body. A movable member is frictionally driven by a combination of a stretching vibration and a bending vibration generated by applying a driving signal to the first polarized portions of the first and second piezoelectric bodies or to the second polarized portions of the first and second piezoelectric bodies.
