For each of several proposed {π}-meson cutoff masses (Λ_π) in the {π}NN form factor, we obtained {ρ}-meson cutoff mass (Λ_ρ) in the {ρ}NN form factor so that the three-body force with these form factors may reproduce the triton binding energy. We calculated the wave function and the exchange current in the Gamow-Teller matrix element for the triton beta decay, consistently using these form factors. The most favorable set Λ_π=0.81 GeV and Λ_ρ=1.13 GeV yielded a triton binding energy of 8.485 MeV (experimentally, 8.482 MeV) and a Gamow-Teller matrix element divided by {}3 0f 0.955 (experimentally, 0.961).
