For two integers m, n with m $leq$ n, an [m,n]-factor F in a graph G is a spanning subgraph of G with m $leq$ d$\_$F/(v) $leq$ n for all v ∈ V(F). In 1996, H. Enomoto et al. proved that every 3-connected Planar graph G with d$\_$G/(v) $geq$ 4 for all v ∈ V(G) contains a [2,3]-factor. In this paper. we extend their result to all 3-connected locally finite infinite planar graphs containing no unbounded faces.
