wherein protruding portions are formed along the width directions at inner circumferential surfaces of the first and second cover portions to restrict the rotations of the first and second connecting portions, respectively.
11. The mobile terminal of claim 2, wherein a hollow portion is formed inside the rotating portion, the first and second connecting portions are flexible and integrally formed while passing through the hollow portion, and a first supporting shaft and a second supporting shaft, fixing the first and second connecting portions, are formed at both ends of the first and second connecting portions, respectively.
12. The mobile terminal of claim 11, wherein the first and second supporting shafts are fixed to the first and second wall portions of the first and second cases, respectively.
13. The mobile terminal of claim 12, wherein the first and second connecting portions are integrally formed, and each of the first and second connecting portions is a corrugated plate having a plurality of corrugations or a mesh.
14. The mobile terminal of claim 2, wherein the rotating portion is a click hinge which includes a housing fixed to the first and second wall portions, and a cam portion protruding from one side of the housing to be inserted into the first or second connecting portion, the camp portion rotating the first or second connecting portion.
