The widths of the decays τ→ K-K+K-ντ and τ→ K-KK¯ ντ are calculated in the U(3) × U(3) chiral quark NJL model. Four channels are considered: contact, axial vector, vector, and pseudoscalar channels. It is shown that the dominant contribution is given by the axial vector channel with an intermediate ϕ meson. The results obtained are in satisfactory agreement with the experimental data.
