PURPOSE: An irradiation angle adjuster of a head lamp for a vehicle according to altitude is provided to drive safely and to obtain the visual field by automatically adjusting the irradiation angle of the head lamp according to the inclination angle during traveling on the uphill or downhill. CONSTITUTION: An irradiation angle adjuster of a head lamp(5) is composed of an altimeter(1) installed in a vehicle to detect the altitude of the vehicle with an electric signal; a control unit(2) detecting the change of altitude by receiving the output signal from the altimeter, and outputting a control signal to a motor driving unit(3) according to the map; the motor driving unit driving or reversing an angle adjusting motor(4) according to the output signal from the control unit; and the angle adjusting motor connected to the head lamp supported and turned up and down by a gear or link, and driven according to the output signal from the motor driving unit to adjust the irradiation angle of the head lamp according to the altitude. The visual field is obtained and safe driving is performed by automatically adjusting the irradiation angle of the head lamp during traveling on the uphill or downhill.
