For example, it has been recognized that two reflecting surfaces are simultaneously aiming as described above. Not always. In such a case, it is impossible to perform aiming individually with the above-described configuration. Therefore, there are two types, one that can separately aim at the same vehicle type and the other that simultaneously. It has to be prepared, which is disadvantageous in terms of productivity and cost.

In the headlamp 1 according to the present invention, in addition to the above-described structure, a passing sight provided on the passing reflecting surface 2 is provided. An interlocking mechanism 7 is provided for the mechanism 5 and the traveling sighting mechanism 6 provided on the traveling reflecting surface 3.

In the above, by attaching the interlocking mechanism 7, one of the drive gear 5d of the passing aiming mechanism 5 and the drive gear 6d of the traveling aiming mechanism 6 is adjusted with a driver or the like, so that both of the reflection surfaces are adjusted. That is, it is possible to aim the passing reflecting surface 2 and the traveling reflecting surface 3 and satisfy the requirement that the aiming of the two reflecting surfaces 2 and 3 be performed by one aiming mechanism.

In this case, the distance between the ball joint 5a and the adjusting screw 5c of the passing aiming mechanism 5 provided on the passing reflecting surface 2 and the traveling reflecting surface 3
Ball joint 6a of the sighting mechanism 6 for traveling provided in the
If the interval between the adjustment screw 6c (not shown) and the adjustment screw 6c is not the same, if the adjustment screw 5c and the adjustment screw 6c are caused to rotate at the same rotational speed, the inclination angles will be different, and accurate aiming will be achieved. It will not be possible.

For example, if the second idle gear 7b is configured to be replaceable, the compatibility can be further expanded. Of course, the drive gears 5d, 6d are replaced with the diameters of the idle gears 7a, 7b.
The diameter may be changed on the d side.

An interlocking mechanism consisting of a flexible shaft having an appropriate length for connecting between the two idle gears is attached, and by operating either one of the drive gears, the aiming mechanism is configured so that the aiming of the two reflecting surfaces can be performed simultaneously. By having a headlight provided, it is a headlight in which two reflecting surfaces are provided in one lamp body,
This eliminates the need to prepare multiple types of headlamps that individually correspond to each law and regulation, even when laws and regulations for the aiming mechanism differ depending on the destination, increasing costs and complicating the production process. It has an extremely excellent effect of preventing the formation of the sapphire.
