In this paper we describe a model of a four-dimensional spherically symmetricblack hole in a limiting curvature theory of gravity. In this theory theEinstein-Hilbert action is modified by adding to the action terms providinginequality constraints on chosen curvature invariants. We demonstrated that insuch a model, instead of formation of the curvature singularity, the spacetimeremains regular in the black hole interior. For black holes with gravitationalradius much larger than the radius $\ell$ of the critical curvature theobtained solutions describe a space exponentially expanding in one directionand periodically oscillating in the other two (spherical) directions.
