PURPOSE: A hinge module for a folding-type portable terminal capable of automatically opening and closing the portable terminal at specific angle is provided to prevent eccentricity by minimizing the friction on single axis in order to automatically open and close the portable terminal. CONSTITUTION: An actuating camera is installed in one end of a shaft(10). A first link frame(20) is fixed to the other side end of shaft. A sliding cam(30) is installed to be rotated and slid. A second link frame(40) is combined and is circulated from a housing in a shaft. A bushing(50) prevents separation of the second link frame according to the pitch of the second link frame.
