In this paper, the lepton flavor violating τ→ℓP(V) (P, V=π0, η, η′, ρ0, ω, φ) and τ→3ℓ (ℓ=e, μ) decays are studied in the framework of the type-III seesaw model, in which new triplet fermions with a zero hypercharge (Y=0) interact with ordinary lepton doublets via Yukawa couplings, and affect tree-level leptonic Z-boson couplings. We investigate the experimental bound from the leptonic Z decay to get constraints on the existing parameters space. We predict that the upper limits on the branching ratios of τ→ℓP(V) and τ→3ℓ can reach the experimental current limits.
