We investigate, in a fully microscopic way, the double gamma-vibrational states in ^<168>Er by means of the selfconsistent-collective-coordinate (SCC) method proposed by Marumori, Maskawa, Sakata and Kuriyama. In applying the SCC method, we propose a new prescription to derive a quantized collective Hamiltonian. The collective potential is defined in terms of the Wigner transform of the quantized collective Hamiltonian. It is different from the potential defined by the energy expectation values with respect to the time-even Slater determinants, and we find that it acquires a much stronger tendency toward the triaxial equilibrium shape than the latter. Numerical calculations show that ^<168>Er is situated just in the transitional region toward the triaxial equilibrium shape.
