Disclosed are a mobile communication device and a hinge structure therefor with improved mechanical strength and outer appearance. The mobile communication device 100 comprises the lower case 11 and the upper case 21 mutually coupled to each other by way of the hinge structure so that the two cases 11, 21 are pivoted to take either the folded position or the unfolded position. The hinge structure comprises: the bearing structure comprising the first bearing portion 16 formed in the first case 11 with open at one end and closed at the other end and the second bearing portion 25, 26, 27 formed in the second case 21 with open at both ends, wherein one end of the second bearing portion 25, 26, 27 is disposed adjacent to one end of the first bearing portion 16 in the axial direction; the pivotal shaft 41 comprising the first shaft portion 41b pivotally mounted on the first bearing portion 16 and supported so as to move in the axial direction and the second shaft portion 41a pivotally mounted on the second bearing portion 25, 26, 27 and supported so as to move in the axial direction , wherein the first and second shaft portions are pivotally coupled ; and the opening 28 formed in the upper case 21 at a location adjacent to the bearing structure in the axial direction so that the pivotal shaft 41 is permitted to pass.
