  Charged-lepton-flavor-violation is predicted in several new physics
scenarios. 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--$4.3) \times 10^{-8}$. These limits are
improved by 30% on average from the previous results.
