We analyze a direct-transmission model of dynamical supersymmetry breaking previously proposed. In the model the gravitino mass is naturally smaller than $1 \mathrm{keV},$ which is required from standard cosmology. We find that there are many distinguishable features with other models: for example the so-called GUT relation among the gaugino masses does not hold even if we consider the GUT models. Furthermore, the gauginos are always lighter than the sfermions since the gaugino masses have extra suppression factors. We also discuss a collider signature ``$\ensuremath{\gamma}\ensuremath{\gamma}+$ missing energy'' in the present model.
