PURPOSE: A door hinge is provided to reduce the manufacturing cost by simplifying an auto-closing structure and not to influence the outward appearance of a door by not being invisible from the outside. CONSTITUTION: A door hinge comprises a foot bearing(1), a shaft seal(2), and a connector(3). The inside of the foot bearing is formed in a female screw and the outside of the shaft seal is formed in the male screw, and the connector is coupled to the upper part of the shaft seal to be separable from the shaft seal freely. |
