Abstract
A motor vehicle headlamp has adjusting means for adjusting the orientation of its reflector by essentially linear displacement of an application point on the reflector. This application point is defined by one end of a threaded rod which includes at its opposite end an adjusting head, and which is threadedly mounted with a first degree of friction in a fixed part of the headlamp. The threaded rod is also threadedly engaged, but with a second degree of friction, in an adjusting cap. The second degree of friction is greater than the first degree of friction.
