Abstract
The headlight for a motor vehicle has with an electromotive adjusting device (5) for adjusting a reflector (2). The adjusting device (5) include an electric motor (7) and a step-down gear unit which are accommodated in a housing part (12) which is arranged within the headlight housing (1). The step-down gear unit includes a small worm gear (8) and a large toothed wheel (9) with radial teeth. A rotational movement of the toothed wheel (9) is transformed via a thread between the toothed wheel (9) and the housing part (12) into a movement of the toothed wheel (9) along an axis (6) determining the adjusting direction. The toothed wheel (9) is connected with the reflector (2) a ball-ended spindle which is held pivotally with one spherical end in a spindle receptacle attached to the toothed wheel so that, when the toothed wheel moves along the axis, the spindle moves to adjust the reflector. A deflecting gear unit with an adjusting part extending outside the headlight housing can be provided, which is coupled to the spindle so that the reflector can also be adjusted manually with the adjusting part.
