Using the mass function obtained by D'Odorico et al. (1991, AAA 117.226), we recalculate the theoretical light curves of SS 433 in the primary eclipse and confront them with observations. We assume that in SS 433 there exists a geometrically thick torus around a compact object, and that the primary eclipse is an eclipse of the torus by a companion of an early-type star. The main parameters are the shape of the tori, the size of the tori, and the binary mass ratio. We obtain light curves for several combinations of parameters. The light curves for sufficiently thick tori are deep at the mid-eclipse and preferable, while those for geometrically thin tori are shallow. The duration of eclipse for a large torus is long and beneficial, while that for a small torus is short. Finally, m at mid-eclipse for a thick torus around a neutron star becomes ~ 0.6 and suitable, whereas for thick tori around a black hole it is ~ 0.3. Hence, under the new mass function, geometrically thick and wide tori around a neutron star can well reproduce the observed light curves of SS 433.
