We obtain quantum deformation of $SU(2,2)$ as a real form of multiparametric $GL(4,C)_{q_{ij},r}$. It is shown that Poincaré subgroup exists for special nonstandard one-parametric deformation only, the deformation parameter $r$ being equal to unity. This leads to commuting affine structure of the corresponding Minkowski space and simple structure of the corresponding Lie algebra, the deformation of the group being non-trivial.12 pages, Latex, HU-SEFT R 1993-15High Energy Physics - TheoryLarge Quantum Poincare Subgroup of q-Conformal Group and q-Minkowski Geometrytext
