PURPOSE: A dual hinge module for a portable terminal is provided to reduce a classification of components by using the same components in a first hinge unit and a second hinge unit. CONSTITUTION: A first hinge unit includes a first rotary shaft member, a first elastic member, a first rotary restriction washer, and a first interdisciplinary washer(127). A second hinge unit includes a second rotary shaft member, a second elastic member, a second rotation restriction washer(136), and a second interdisciplinary washer(137). The second rotation restriction washer includes a rotation restriction protrusion(136b). The rotation restriction protrusion restricts the rotation of the second rotary shaft member by selectively bumping into a second stopper. The second interdisciplinary washer is fixed at end unit of the second rotary shaft member in an external side of the second rotary restriction washer. A linear rotation permission unit is formed at one side of the second interdisciplinary washer.
