We investigate the propagation of Ultra High Energy Cosmic Rays (UHECRs) with energy E>1019 eV in the regular component of magnetic field of our Galaxy. Model of the Galactic magnetic field with both symmetric and asymmetric cases of halo magnetic field have been considered. The maps of angular dependence of deflection of UHECRs have been constructed. Concentration of magnetic field in the Galactic disk results in some decreasing of initially isotropic extragalactic flux of cosmic rays for E≤ 5\cdot 1019 eV from a Galactic disk zone. This effect is more prominent in case of asymmetric halo magnetic field model. We estimate also a contribution of a random component of Galactic magnetic field to the deflection of UHECRs.
