A gear comprising a metal toothed portion 49 and a synthetic resin tubular portion 50 is rotatably mounted in a hole in, a rear wall 39 of a housing by a snap-fit. The tubular portion has integral elastic, engagement pieces 53 with claws 54 which engage the inner end of a tubular section 42, surrounding the hole, another surface of the gear engaging the outside of wall 39. The gear is used in the initial adjustment of a headlamp levelling mechanism. The headlamp levelling mechanism subsequently operates using an electric motor 59 which drives a worm 61 to rotate a gear 11 and so effect adjustment via a screw an nut device. <IMAGE>
