Drive unit for a vibrating spiral conveyor, consisting of a base part, with which an opposed-action part and a fastening part, the motion of which is coupled with that of a pot, are connected flexibly, the former over several first leaf spring elements and the latter over several second leaf spring elements, it being possible to bring the opposed-action part and the fastening part into an opposite, oscillating, torsionally vibrating movement about a central axis of rotation, characterized in that the leaf spring elements ( 10, 11 ) are disposed in such a manner that their central transverse axis (M), which is perpendicular to the longitudinal axis, intersects a leaf spring element ( 10, 11 ) essentially in the center with respect to its length and extends parallel to the lateral surfaces of the spring, is disposed essentially radially to the axis of rotation (D).
