An unlocking apparatus of a door is provided to narrow the gap between the door and the door frame and improve the closure force according as the rod is moved to the inner direction of the door frame when the door is locked. An unlocking apparatus of a door is selectively opened and closed by a rod(30) inserted and withdrawn to a unit unlocking part(10). The unit unlocking part is combined with a rod guide unit(20) at a case having an opened upper surface. The rod is formed with a taper shape expanded from the lower part to the upper part and inserted to the inner front side of the case by the rod guide unit. A separation prevention piece(16) is formed like a rectangle having a predetermined thickness and provided with plural penetration holes(161,161') between both ends and a support shaft pressure unit(162) integrally formed to have a recessed shape at one end of the both ends. |
