Abstract: An electric hand-held power tool, in particular a hammer drill and/or chipping hammer, having an electropneumatic impact mechanism which has a transmission housing, a guide tube arranged at least partially in the transmission housing, an exciter piston that is movable in an axial direction in the guide tube, a connecting rod coupled to the exciter piston, and an eccentric wheel which is coupled to the connecting rod on one side and is mounted so as to be rotatable with respect to the transmission housing via an end plate of the transmission housing on the other side, wherein the transmission housing is subdivided at least into a main shell and a cover shell separate from the main shell, such that the guide tube is braced against the main shell at least partially by the cover shell.
