Title: Chain saw handle and vibration isolation system

Abstract: A chain saw including an improved suspension system characterized by a U-shaped hand grip means extending transversely across a longitudinal median plane of a guide bar means, with the U-shaped hand grip means being contiguous with a longitudinally extending rear handle and serving to house, at least in part, a portion of the chain saw vibration isolation system. Generally longitudinally aligned vibration isolation units are constrained by abutment means and axially oppositely directed mounted shaft means to impede axially oppositely directed movements of a vibration generating assembly relative to the chain saw suspension system.
