In accordance with the invention, at least the connection zones of the housing () to the motor pot () and the attachment part () are configured in a cylindrical manner while the connection zone are formed by means of a rotary motion of the housing () and/or the motor pot () and/or the attachment part () in a radial direction. The connection zones are configured form-fittingly in an axial direction. This type of connection is realized by means of meshing threads. The linear drive according to the invention is particularly suitable for driving the adjustable components of a slatted frame or armchair.
