  The cluster $^4\rm He+\Lambda+\rm n$ model is applied to describe the
$^6_\Lambda$He hypernucleus. The consideration is based on the configuration
space Faddeev equations for a system of non-identical particles. A set of the
pair potentials includes the OBE simulating (NSC97f) model for the $\Lambda \rm
n$ interaction and the phenomenological potentials for the $\alpha\Lambda$ and
$\alpha \rm n$ interactions. We calculated energies of spin (1$^-$,2$^-$)
doublet. For the 2$^-$ excitation energy, the obtained value is 0.18 MeV. The
hyperon binding energy of the bound 1$^-$ state is less than the experimental
value, which may be an evidence for violation of the exact three-body cluster
structure.
