The iron lines from Seyfert 1 galaxies exhibit broad red-wings in general, which are attributed to the relativistic accretion disk close to the black hole. The line profile provides us with the information of the geometry of the accretion disk and the central source. We examine a time behavior of the iron line in accordance with a spectral variability of the power-law continuum of bright Seyfert galaxy Mrk 841 observed with ASCA. The emission mechanism and the structure around a black hole are discussed to accommodate both the spectral change of the continuum and the line profile change. .
