Abstract
The headlamp is structured such that a reflector 4 is supported within a lamp body 2 so as to be inclinable with respect to the lamp body 2 and, by rotatively operating an aiming screw 20 which extends through and forwardly of the lamp body 2 and is supported rotatable in the extend-through portion thereof, the reflector 4 is inclined right and left with respect to the lamp body 2 by an amount equivalent to the amount of rotation of the aiming screw 20 to thereby be able to adjusted the right and left illumination angle of the headlamp. In the headlamp, there is formed in the aiming screw 20 a male screw portion 20a which extends out backwardly of the lamp body 2, there is provided in the lamp body 2 a guide element 60 which extends in parallel to the male screw portion 20a, between the male screw portion 20a and guide element 30, there is disposed an inclination measuring device including a nut element 50 which is threadedly engageable with the male screw portion 20a and is advanceable and retreatable along the guide element 60 in linking with the rotation of the aiming screw 20, a cursor 74 provided in the nut element 50, and a linear scale 63 provided in the guide element 60, and there is formed in the root position of the male screw portion 20a a crown gear 23 which is engageable with the tip edge D.sub.1 of a driver D inserted from a direction at right angles to the aiming screw 20, thereby facilitating the rotative operation of the aiming screw 20.
