  In this article, we study the structure of the \rho meson in the framework of
the coupled rainbow Schwinger-Dyson equation and ladder
  Bethe-Salpeter equation with a confining effective potential. The u and d
quark propagators get significantly modified, the mass poles are absent in the
timelike region, which implements confinement naturally. The Bethe-Salpeter
amplitudes of the \rho meson center around zero momentum and extend to the
energy scale about $q^2=1GeV^2$, which happens to be the energy scale of chiral
symmetry breaking, strong interactions in the infrared region result in bound
state. The numerical results of the mass and decay constant of the \rho meson
are in agreement with the experimental data.
