Abstract: A manual and an electromotive actuatable adjusting apparatus for a reflector of a motor-vehicle headlight (1) are arranged together in a common housing. An adjusting pin (4), which is attachable to the reflector, can be moved along its length axis by both the manual and the electromotor adjusting apparatus. An end portion (6) of the adjusting pin, directed away from the reflector, slidably engages in a blind hole (7) of a gear (9) to be rotatable therewith. The gear is sealingly seated in a hollow cylinder (10) of a cover (2) and its hub (8) rotatably engages, while being axially fixed, in a bearing opening (13) in an end wall (12) closing off the hollow cylinder to the outside. There are a plurality of openings (14) in the hollow cylinder which allow a rod-shaped auxiliary tool (11) to be inserted therethrough so that when the tool is rotated about its length axis tooth-like protrusions (15) thereof engage in teeth (16) of the gear.
