For the synthesis of superheavy elements, it is indispensable to divide the fusion process into two steps; Overcoming the Coulomb barrier and passing over the conditional saddle or the ridgclinc. To facilitate the understanding of the mechanism which explains the fusion hindrance, we first employ an analytic model with an inverted parabola for the saddle. Then, results by realistic calculations are given for the cold fusion. Ambiguities of the model are also discussed for future investigations. Since the model is general, it is applied to incident channels with neutron-rich projectiles and/or targets. These are necessary for synthesis of nucleides in so-called superheavy island around Z=114 and N = 184.
