We use heavy vector meson SU(2){sub {ital L}}{times}SU(2){sub {ital R}} chiral perturbation theory to predict differential decay distributions for {tau}{r_arrow}{rho}{pi}{nu}{sub {tau}} and {tau}{r_arrow}{ital K}{asterisk} {pi}{nu}{sub {tau}} in the kinematic region where {ital p}{sub {ital V}}{center_dot}{ital p}{sub {pi}}/{ital m}{sub {ital V}} (here {ital V}={rho} or {ital K}{asterisk}) is much smaller than the chiral symmetry-breaking scale. We also predict the rate for {tau}{r_arrow}{omega}{pi}{nu}{sub {tau}} in this region (now {ital V}={omega}). Comparing our prediction with experimental data, we determine one of the coupling constants in the heavy vector meson chiral Lagrangian. {copyright} {ital 1996 The American Physical Society.}
