The branching fractions of the decays τ → a1πντ, τ → K1πντ and τ → K1Kντ are calculated in the framework of the extended U(3) ×U(3) chiral Nambu-Jona-Lasinio model. There are no experimental data for these decays in the present time, thus the obtained results are considered as predictions. The comparison of these results to the theoretical results of other authors is carried out.
