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).
