PROBLEM TO BE SOLVED: To provide an optical axis adjustment device for a headlight, which is able to adjust an optical axis more accurately.SOLUTION: Inclination of a vehicle body is determined on the basis of a front-wheel load and a rear-wheel load, and an optical axis is adjusted on the basis of it. The front-wheel load and the rear-wheel load are parameters that change in correspondence with a change in inclination of the vehicle body. Even if the entire height of the vehicle body is changed as in a case of low down, the front-wheel load and the rear-wheel load do not change unless the vehicle body inclines. Therefore, erroneous correction of an optical axis as in optical axis adjustment on the basis of an amount of change in the height of the rear wheel axle can be reduced. Accordingly, the optical axis adjustment device 100 can adjust an optical axis more accurately.SELECTED DRAWING: Figure 1 |
