  The relativistic calculations of the electromagnetic form factors, static
moments and lepton decay constant of the $\rho$-meson are given in the
framework of the instant form of the relativistic quantum mechanics with
different model wave functions. The modified impulse approximation (MIA) is
used for the electroweak current operator. MIA provides Lorentz covariance and
conservation law for current operators. The developed approach gives the
nonzero quadrupole moment due to the relativistic Wigner spin rotation in the
$S$-state of the quarks in $\rho$-meson
