A hinge device for a portable terminal having a first housing and a second housing rotatably coupled to the first housing such that the second housing is moved between an opened position and a closed position with respect to the first housing is provided. The hinge device extends in one direction to provide a hinge axis, which is a rotational center of the second housing. The hinge device allows the second housing to linearly move in a hinge axis direction and generates rotational force to rotationally shift the second housing into the opened position or the closed position with respect to the first housing about the hinge axis as the second housing linearly moves in the hinge axis direction. A user easily and conveniently opens or closes the portable terminal by horizontally moving one housing with respect to the other housing.
