We update the analysis of $\\tau$ lepton decays into a light charged lepton ($\\ell$ = $e^{\\pm}$ or $\\mu^{\\pm}$) and a vector meson ($V^0$ = $\\rho^0$, $\\phi$, $\\omega$, $K^{\\ast0}$, or $\\overline{K}{}^{\\ast0}$) using 980 fb$^{-1}$ of data collected with the Belle detector at the KEKB collider. No significant excess of such signal events is observed, and thus 90% credibility level upper limits are set on the $\\tau \\rightarrow \\ell V^0$ branching fractions in the range of (1.7--$4.3) \\times 10^{-8}$.
