We have determined the inclination of the axis of the HCO+torus in NGC 7027 to the line of sight, based on interferometrie observations and model calculations. We found that the deduced inclination of the HCO+ torus is misaligned with the inclination of the major axis of the ionized core. The result may imply the precession of the axis of the axisymmetric mass loss.
