The triple Reggeization of the spin-dependent inclusive reaction rr+N-7n+anything is discussed, starting from the Lorentz invariant amplitude. Due to the kinematical factor, one-particle spectrum by polarized nucleon be'comes zero at forward direction. Being different from rrN elastic scattering case, dip (non-sense zero) may not appear at ap(t) =0, but may appear at a.(t) = -2, -4,-·····. The energy square s and missing mass square s1 dependence of the one-particle spectrum is also given. We also discuss the triple Pomeron coupling constant.
