PURPOSE: A hinge device is provided to improve convenience by spreading one member against the other member to the position of the spread angle at once in unfolding, and by stopping the member at the specific angle in folding. CONSTITUTION: A hinge device is composed of a cam driving member(10) having a couple of driving cam protrusions forming continuous concave and convex portions; a first cam driven member(20) stopping in rotating the cam driving member in the direction and rotating together in rotating in the opposite direction; a second cam driven member(30) linearly moving by the first cam driven member rotating in the opposite rotation of the cam driving member; an elastic member(40) elastically and supporting first and second cam driven members; a housing(50) containing the parts; and a supporting shaft(60) penetrating the center of the parts contained in the housing and supporting parts movably. |
