A hinge structure for a mobile communication terminal includes a drive cam arranged to be linearly displaced along a hinge axis, a drive shaft arranged to face the drive cam to be rotated about the hinge axis according to linear displacement of the drive cam, a follower shaft arranged to surround the drive shaft to be rotated along with the drive shaft, a follower cam arranged to face the follower shaft to be linearly displaced along the hinge axis according to rotation of the follower shaft, and an opening/closing resilient member for pushing the follower cam against the follower shaft.
