[Function] When the left and right aiming screws are rotated,
The tilting member tilts with respect to the reference member (tilts about the tilting central axis), and the nut member moves back and forth along the male screw portion of the screw. The tilting amount of the tilting member with respect to the reference member due to the rotation of the aiming screw (the moving amount in the front-back direction of the point where the tilting member is supported by the lateral aiming screw) is proportional to the moving amount between the slide member and the guide member. The tilting amount of the tilting member with respect to the reference member, that is, the deviation amount of the irradiation angle of the headlamp appears as a change in the scale between the slide member attached to the nut member and the guide member. Therefore, it is possible to know from the change in the scale whether the irradiation angle of the headlamp in the left-right direction is proper, and if not, the deviation amount. If there is a deviation, the aiming screw may be used to adjust the irradiation angle so as to eliminate the deviation on the scale.
