The triaxial superdeformed bands in odd mass nuclei are analysed by applying the Holstein-Primakoff transformation both to the total angular momentum and to the single-particle angular momentum in the triaxial rotor model. The special attention is paid to the D_2 symmetry in the Hamiltonian. By comparing this algebraic expression with the numerical results from the exact diagonalization of the rotor Hamiltonian, the quantum numbers are assigned to each level.
