PURPOSE: A light distribution plate conveying device for a light distribution tester of a vehicle head lamp is provided to obtain a minute value by controlling a light distribution plate with a conveying motor and to precisely test and measure a luminous intensity, a speed of light, an intensity of illumination, and an irradiation angle of a head lamp by using a light receiving lens. CONSTITUTION: A light distribution plate conveying device for a light distribution tester of a vehicle head lamp comprises a coupling member(4), a conveying screw part(42), a conveying motor(5), and a rotational conveying screw bar(51). A plurality of the coupling members fixes each edge of a light distribution plate(2). The conveying screw part is formed one side end part of one coupling member among the plurality of the coupling members. The rotational conveying screw bar is connected to the conveying motor. The conveying screw part is coupled with the rotational conveying screw bar by a screw nut.
