Abstract

The invention relates to a linear drive device having a housing element in which at least one drivable actuating element is arranged, a guide unit which is coupled to the actuation element and moves relative to the housing element between two stroke end positions in linear direction, a stroke limiting device, by means of which a first stroke end position and a second stroke end position of the guide unit are adjustable, wherein the stroke limiting device has a first stop and a first counterstop for setting a limit of the first stroke end position and a second stop and a second counterstop for setting a first limit of the second stroke end position, wherein the stroke limiting device has a third stop which is adapted to set a second limit of the second stroke end position adjusted with the first counterstop.
