Abstract
A chain saw guide bar comprises a guide bar body and a nose assembly coupled to an end of the guide bar body, the guide bar body having a longitudinal tongue projecting centrally from an end thereof and thinner core plates extending laterally from opposite sides of the tongue, the nose assembly being composed of a pair of side plates having recesses defined centrally in tail ends thereof and receiving the tongue fitted therein, the body and the nose assembly being coupled together by rivets inserted through the side plates and the core plates with the core plates inserted between the side plates. The core plates may or may not project beyond a distal end of the tongue. The end of the guide bar body and the tail end of the nose assembly are held in abutment at a position spaced 90 mm or preferably more from a tip end of the nose assembly so that the guide bar body will not be adversely affected by hitting engagement with a saw chain.
