A hinge device is disclosed for interconnecting a first member with a second member for relative rotational movement, the hinge device comprising: a rod means connected with the first member; a sleeve member for receiving the rod means for relative rotation therewithin, the sleeve member being connected with the second member and having an interior surface extending longitudinally therethrough, the interior surface being in contact with the outer surface of the shaft means in order to provide a friction force between the shaft means and the sleeve member, the interior surface including a plurality of contact regions for exerting different friction forces on the shaft means.

[ What is claimed is:] [1.] A hinge device for interconnecting a first member with a second member for relative rotational movement, said hinge device comprising:a first cam being rotatable together with said first member;a second cam being rotatable together with said second member, said second cam being slidable in a direction of an axis of the rotational movement independently from said second member;a shaft means coaxially supporting said first cam and said second cam so that they can relatively rotate;a biasing means for pressing said first cam and second cam to each other,wherein one of said first cam and said second cam has a projection on one end thereof, the other one of said first cam and said second cam having a concavity and a flat portion on one end thereof, said concavity being formed for receiving said projection when said second cam is located in a predetermined range of pivot angle, and said flat portion being formed so as to stably support said projection when said second cam is located in a range other than said predetermined range of pivot angle.
