Abstract:
1. A mobile communication terminal comprising: (a) a main housing comprising a first hinge axis formed on one end; (b) a connection member hingedly connected to the main housing so as to be opened from and closed into the main housing around the first hinge axis, and comprising a second hinge axis spaced apart from and perpendicular to the first hinge axis; and (c) a rotational housing rotatably connected to the connection member, wherein the rotational housing rotates around the second hinge axis, and the second hinge is connected to an upper surface of the rotational housing opposite to the connection member, and the rotational housing includes at least one convex arc-shaped end having a designated radius of curvature, wherein the connection member further comprises an auxiliary member formed on one end of the connection member and being concave arc-shaped with the designated radius of curvature, thereby forming a stepped side surface enabling smooth rotation of the rotational housing around the second hinge axis.
