ABSTRACT:
An electric motor operated adjusting drive has a housing with an opening, a threaded rotary spindle arranged in the housing and having an axis, an adjusting nut arranged on the spindle axially displaceable and non-rotatable, and an adjusting member arranged in the housing and sealed relative to the latter. The adjustment member is actuated by the adjusting nut so as to displace linearly outwardly of the housing through the opening. The adjustment member is formed by a hollow body which is thin-walled and surrounds the threaded spindle. The adjustment member is sealed inwardly relative to the threaded spindle and outwardly relative to the opening of the housing.
