Three-body-force contributions entering three-nucleon equations are discussed within the relativistic cluster-dynamical scattering formalism recently proposed by Haberzettl. It is argued that, in addition to the three-body forces usually taken into account, there is an effective enhancement of two-nucleon-force contributions in the medium of three nucleons. The dominant enhancement of this type, a one-pion-exchange three-body force, is included in a five-channel triton binding-energy calculation based on the Paris potential. It is found to provide an increased binding of about 0.6 MeV, a value which closely corresponds to the amount by which the binding energy obtained in coupled-channel calculations with explicit Δ degrees of freedom differs from experiment.
