The Michel parameters are fundamental characteristics of
$\mu$ and $\tau$ leptons
which determine the kinematic distribution of daughter particles from their leptonic
The comparison of experimentally-measured values versus the Standard model predictions allows us
to test the Lorentz structure of weak interaction in model independent way.
We review the tau Michel parameter measurements performed before and
present our recent measurements by Belle experiments.
