<p>PURPOSE: A hinge apparatus is provided to keep a coupling state by itself without using a latch, thereby safely keeping units when the hinge apparatus units are folded. CONSTITUTION: The first cam(130) moves on a rotating shaft straight, rotates together with the first unit and includes the first concavo-convex sloping about a rotation direction. The second cam(150) rotates on the rotating shaft, rotates together with the second unit and includes the second concavo-convex corresponding to the first concavo-convex. An elastic member(160) adheres closely the first and the second cams each other. A riveting connecting unit is formed in both ends of the rotating shaft.</p> |
