Abstract
An adjusting device for automatically actuating a vehicle door of a motor vehicle includes first and second tubular housings connected between a body of the vehicle and the door. A spindle drive includes a spindle driven by an electric-motor drive, a spindle nut threaded on the spindle, a push rod that bears the spindle nut, and a tubular guide part enclosing the push rod and the spindle nut. The tubular guide part is provided with a shape complementary to a shape of the spindle nut and secures the spindle nut against rotation. The tubular guide part is produced by a plastic forming process on a suitable metal tube. A cylindrical spring assists the spindle drive enclosing the tubular guide part. Spacers are provided over an outer circumference of the tubular guide part to reduce friction between the cylindrical spring and the tubular guide part.
