• a transmission is advantageously provided which has fewer components than the arrangements known from the prior art, as a result of which the adjusting device requires less space overall.
• This is achieved in particular by the fact that the worm and the threaded shank or bolt are in direct engagement.
• the threaded shaft or bolt is rotatably mounted relative to the adjusting housing. The worm shaft is then rotated via the worm connected to the threaded shaft or bolt in order to adjust it axially in the desired direction.
• the axes of the worm and of the threaded shaft or bolt are at an angle , preferably at a 90 ° angle, intersect.

• the screw of a bushing of the adjusting housing is rotatably mounted. It is particularly preferred if the socket is arranged releasably releasably in the adjustment. This procedure makes it possible to optionally provide a screw in the adjusting device during production of the adjusting device or else not. Because the threaded shank or bolt is rotatably mounted in a thread of the adjusting device, it is also possible to adjust the object by direct rotation of the threaded shaft or bolt. A more comfortable adjustment is given when the axial Ver ⁇ shift of the threaded shaft or bolt can be done by means of the then provided in the adjustment screw.
• the preferred screw adjustment device may, for example, be reserved for articles of a higher price category during manufacture, while articles of a lower price category can only be adjusted by direct rotation of the threaded shaft or bolt since the screw is omitted therefrom.
• the screw is formed 1 or 2-course aus ⁇ .
• the choice of how many gears the thread of the screw is formed depends on which angle of rotation of the screw which axial path of the Ge threaded stem or bolt is to be actuated, or which forces on the toothing on the threaded shaft or bolt may act without this being damaged in use.
• the suitable choice ultimately depends on which object is to be adjusted by means of the adjusting device according to the invention.
• the threaded shaft or bolt and / or the worm can be made of a plastic, in particular by means of an injection molding process, or a metal.
• the threaded shaft may preferably be formed in one or more parts, in particular in two parts, of a tubular element and a threaded rod. The use of metal in this case allows particularly long-lived adjusting devices, since frequent operation will not lead to significant wear.
