PROBLEM TO BE SOLVED: To make a proper optical axis adjustment of a head lamp for a vehicle, considering an influences by a loading amount, a loading position, etc. by a simple constitution. SOLUTION: A three-dimensional map for determining an ideal optical axis direction from output values of front axis sensor and rear axis sensor of the vehicle is stored in a control device. The three-dimensional map determined for every type of vehicles by an experiment in advance is used. The control device determines the ideal optical axis direction determined from the output values of the front axis sensor and the rear axis sensor, and the three-dimensional map, transmits a driving signal to an actuator of the head lamp, based on the optical axis direction, and makes the optical axis adjustment.
