The traditional nuclear shell model approach is extended to include
many-body forces. The empirical Hamiltonian with a three-body force is constructed for the identical nucleons on the 
shell. Manifestations of the three-body force in spectra, binding energies, seniority mixing,
particle-hole symmetry, electromagnetic and particle transition rates are investigated.
It is shown that in addition to the usual expansion of the valence space within the tranditional two-body shell model, the three-body component in the Hamiltonian can be an important part improving the quality of the theoretical approach.
