ABSTRACT:
The invention relates to a guide bar having a main member made of solid material for a motor chain saw. The guide bar has two flat sides and narrow edges defining a saw chain path. A cutout extends through the main member of the guide bar for reducing weight. The openings in the main member defined by the cutout are closed by cover plates for maintaining the stiffness and are attached to the main member of the guide bar. A fill body is seated in the cutout with an approximately precise fit and is connected to the cover plates in a force-transmitting manner. In this way, a higher torsion stiffness is obtained while at the same time retaining the reduction in weight.
