Abstract
A feed guide mechanism for guiding a reciprocating movable member with a guide member having tabular elastic members forming a guide surface for guiding the reciprocal movement of the movable member on one surface thereof. A piezoelectric member with alternately polarized portions are attached to an opposite surface of the guide member. The piezoelectric member undergoes a polarization so that application of an alternating current produces a standing wave to urge the movable member upward and reduce friction.
