PURPOSE: A door-opening test device is provided to easily measure the angle change of a door generated in applying predetermined load while the door is completely opened without substituting into an angle calculation formula. CONSTITUTION: A fixed device fastened to a roof of a vehicle by magnetic force is composed of a magnetic base(10) fixed by self-magnetic force and a fixing member(11) connected and installed integrally in the upper center of the magnetic base to fasten a length adjusting device. The length adjusting device combined to an upper part of the fixed device to regulate the length comprises a rotary member(20) hinge-combined to the fixing member to adjust vertically the angle and formed with helixes; a length adjusting member(21) helix-combined to the rotary member and fastened in regulating the length of an angle check device; and a connecting member(23) helix-combined to the length adjusting member to regulate the length of the angle check device. The angle check device connected with the length adjusting device to measure the angle changed in applying the predetermined load to the door is composed of a fixed shaft(30) installed upward at the side of the connecting member; an angle frame(31) disposed at the fixed shaft to rotate in applying predetermined load to a door; an angle meter(33) installed to the fixed shaft at the predetermined gap between the angle frames to check the angle change of the door; and a pin(32) disposed at the side of the angle frame to transmit the angle change of the door to the angle frame.
