Abstract
The invention relates to a guide bar for the saw chain of a motor-driven chain saw. The guide bar has a guide groove which extends about the periphery thereof wherein the saw chain runs. The guide groove is delimited by two side plates which are tightly connected to each other and are held at a spacing relative to each other. The side plates are also approximately coincident with each other. At least one of the side plates has a connecting part which projects in a direction toward the other side plate. This connecting part lies with a contact surface on a corresponding counter surface of the other side plate. The connecting part of a side plate extends through the guide groove up to the other side plate and there contacts with its contact surface the counter surface of the other side plate. The contact surface and the counter surface lie approximately perpendicular against each other. In this way, a simple manufacture of the guide bar and an easy assembly thereof is guaranteed.
