(57) A glass door hinge is revealed. The glass door hinge includes a fixed hinge seat disposed on a fixed glass door end and a corresponding movable hinge seat arranged at a movable glass door end being pulled or pushed. The fixed hinge seat and the movable hinge seat are pivoted and assembled with each other. A stopper is mounted on a pivot end of the fixed hinge seat for holding the fixed glass door end. Thus the stopper supports the fixed glass door end for stabilizing load of pivot ends of the fixed hinge seat and of the movable hinge seat. Thus even after the movable glass door end being opened and closed for multiple times, the glass door will not fall off so as to meet safety requirement of the glass door. Moreover, a shore that is against by an elastic member is mounted correspondingly on the main body of the fixed hinge seat. By the shore against the pivot end of the movable hinge seat correspondingly, the closeness of the glass door being pulled or pushed is adjusted. Furthermore, an integrated waterproof stick is arranged at the moveable glass door being pulled/pushed. While being assembled, the waterproof stick is not segmented on the position corresponding to the hinge so as to have superior water resistance.
