Abstract
A guide bar for a saw chain of a motor chainsaw has two side plates having a longitudinal extension. At least one longitudinal stay for fixedly connecting the side plates to one another is provided such that the side plates are positioned substantially congruent and parallel to one another and define a peripheral guide groove therebetween. The longitudinal stay preferably extends in a direction of the longitudinal extension over most of the longitudinal extension of the side plates. The longitudinal stay has contact surfaces and the side plates have support surfaces extending perpendicular to the center plane of the guide bar extending parallel to the side plates. The contact surfaces rest on the support surfaces.
