PURPOSE: A door checker decreases man-hour to install a door to a body and does not need to be separately installed to increase the efficiency of assembling work. CONSTITUTION: A door checker comprises a checker(4) and a checking device. The checker(4) is installed rotatably at a rotary hole by a rotary axis(2) of the second hinge(57) fixed at a body and has a check bar(3) horizontally extended. The checking device is rotatably connected with the second hinge(57) and is installed to the first hinge(56) so that the check bar(3) is guided and fixed at a prescribed location when a door is opened/shut. The check bar(3) and a roller(8) are installed between the first and the second hinges(56, 57) and slide to be fixed by a fixing groove(5) to act as a checker.
