摘要： A door hinge of the type comprising a first metal plate having one vertical side edge formed integral with a pin and a second metal piece having one vertical side edge formed integral with a second knuckle cylinder into which is fitted the pin. A load plug is slideably fitted into the second knuckle cylinder for engagement with the upper end of the pin and the second knuckle cylinder is formed with an engaging portion for preventing the load plug from being displaced from a predetermined position. A compression spring means is loaded in the second knuckle cylinder above the load plug so as to press the load plug against the engaging portion, whereby a load applied axially to the pin is carried by the compression spring means through the load plug. When the upper or lower side edge of the door interferes with a gate frame due to an earthquake or the like, the first and second plate metals are caused to move toward or away from each other so that the interference between the door and the gate frame is eliminated and the door is moved upwardly or downwardly relative to the gate frame. Therefore even when the gate frame is distorted, the door can be positively opened.
