Abstract: A hinge mechanism includes a plurality of linkage units, each including a base bar and two rotating assemblies pivotally connected with two carrying sections of the base bar. Each rotating assembly has a synchronous rotation bar, a friction plate and a torsion plate. The friction plate has a first major plate body and a friction increasing portion inclined outwardly from the major plate body. The rotating assemblies are turnable relative to the base bar between unfolded and folded positions. During the turning, the friction increasing portion is gradually overlapped upon and in frictional contact with the torsion plate so as to increase a friction force for providing a stable turning.
