摘要：
A guide bar has a main portion and a nose portion. The main portion has a convex outer end and the nose portion a mating concave inner end. A tongue extends from the nose portion for insertion in a receiving slot in the main portion and rivets fasten the tongue to the main portion. A relief is formed at the junctions of the edges of the nose portion and main portion, i.e., at the points where the saw chain passes from the main portion to the nose portion and then back to the main portion of the guide bar.
