<p>The invention relates to an adjusting device (3) having a spindle drive (11), in particular for automatically actuating the vehicle door (2) of a motor vehicle (1), the spindle drive (11) comprising a spindle (13), which can be rotated by an electric-motor drive (100), and a spindle nut (15) which, when the spindle (13) is rotated, can be displaced along the longitudinal axis (16) of the spindle (13) in a guide (24), from a retracted rest position into an extended position. The invention proposes a spindle drive (11) having a one-piece spindle nut (15) which has the form of a tubular push rod which extends in the direction of the longitudinal axis (16) of the spindle (13). This push rod-shaped region of the spindle nut (15) then acts, via a corresponding connecting part (6), on a part (2) of the motor vehicle that is to be adjusted, that is to say, for example, the tailgate (2) of the motor vehicle (1).</p> |
