  Compressional properties of nuclear matter are studied by using the mean
field theory with the excluded volume effects of the nucleons. It is found that
the excluded volume effects make it possible to fit the empirical data of the
Coulomb coefficient $K_{c}$ of nucleus incompressibility, even if the volume
coefficient $K$ is small($\sim 150$MeV). However, the symmetry properties favor
$K=300\pm 50$MeV as in the cases of the mean field theory of point-like
nucleons.
