Abstract: A mobile communication terminal includes an upper body, a lower body and a swivel hinge unit connecting the upper body and the lower body such that the lower body swivels about the upper body. Before the swiveling movement, the upper and lower bodies form a horizontal axis, and the swivel hinge unit has a central axis arranged with an inclined angle with respect to the horizontal axis. After the swiveling movement, the upper and lower bodies are arranged relative to each other to form an obtuse tilting angle. The inclined angle of the swivel hinge unit is ½ of the tilting angle, and the tilting angle can be 5° to 30°. The upper body includes a display, and the lower body includes a key input unit.
