ABSTRACT:
A vehicular headlamp in which the zero point adjustment axis can be freely set and the zero point adjustment can be achieved with ease. An inclination member with a light reflecting surface for setting the axis of irradiation of a lamp is supported by an aiming mechanism in such a manner that the inclination member is inclinable about both horizontal and vertical axes with respect to a reference member arranged behind the inclination member. An inclination detector is provided which includes a stationary holder secured to the reference member, a movable holder coupled to the stationary holder in such a manner that the movable holder is slidable forwardly and rearwardly, a slider engaged with the movable holder in such a manner that the slider is slidable forwardly and rearwardly, the slider being elastically urged so that the front end thereof is abutted against the inclination member and so that the slider is allowed to slide as the inclination member inclines about the vertical axis, and a zero point adjustment shaft having a gear mounted thereon which is engaged with a rack formed on one side of the movable holder. The zero point adjustment shaft is supported by the stationary holder and extends in a direction perpendicular to the direction of slide of the movable holder.
