With the help of the improved Monte Carlo renormalization-group scheme, wenumerically investigate the renormalization group flow of the antiferromagneticHeisenberg and XY spin model on the stacked triangular lattice (STA-model) andits effective Hamiltonian, 2N-component chiral $\phi^4$ model which is used inthe field-theoretical studies. We find that the XY-STA model with the latticesize $126\times 144 \times 126$ exhibits clear first-order behavior. We alsofind that the renormalization-group flow of STA model is well reproduced by thechiral $\phi^4$ model, and that there are no chiral fixed point ofrenormalization-group flow for N=2 and 3 cases. This result indicates that theHeisenberg-STA model also undergoes first-order transition.Comment: v1:15 pages, 15 figures v2:updated references v3:added comments on  the higher order irrelevant scaling variables v4:added results of larger  sizes v5:final version to appear in J.Phys.Soc.Jpn Vol.72, No.
