Generalized transversality theorem for Cr mapping F(u,s):M×S→N is established in infinite dimensional Banach manifolds M, S, N. If the mapping F (u, s) is generalized transversal to a single point set {θ}, and fs(u) = F (u, s) is a Fredholm operator in the sense of parameter s, then there exists a residual set Σ⊂ S, such that fs(u) are generalized transversal to {θ} , for all s∈Σ.
