Abstract: We construct a phenomenological three-nucleon force (3NF) model that gives a good description of polarization observables in elastic nucleon-deuteron ($N\text{\ensuremath{-}}d$) scattering at a low energy together with a realistic nucleon-nucleon force and a 3NF arising from the exchange of two pions. Parameters of the model, which consists of spin-independent, spin-orbit, and tensor components, are determined to reproduce the three-nucleon binding energy and polarization observables in $N\text{\ensuremath{-}}d$ scattering at 3 MeV. Predictions of the 3NF model on $N\text{\ensuremath{-}}d$ polarization observables at higher energies are examined, and the effects of each component on the observables are investigated.
