PURPOSE: A hinge for a hinged door is provided to open a hinged door at set degrees and to maintain the opened state of the hinged door using a small amount of power. CONSTITUTION: A hinge(100) for a hinged door comprises a fixture(10) and a rotator(20). The fixture and the rotator have first and second foot bearings(12,22). The first and second foot bearings have through holes(11,21) so that a hinge shaft(H) can be inserted. A guide groove(23) having a slope is formed in the second foot bearing. Angle regulation units(24) are integrally formed in both ends of the slope of the guide groove. A key groove(13) having a fixing protrusion(14c) is formed in the first foot bearing. The fixing protrusion fixes the opened angle of a hinged door. |
