Abstract
A guide bar for a chain saw includes three layers. The two outer layers are defined by side plates which can be welded together by means of inserts and the intermediate member located therebetween is held in a form-tight manner by means of the inserts that are welded to the side plates. Because of this configuration, the intermediate member may be made of plastic or aluminum thereby reducing the weight of the chain saw. The guide bar with this sandwich configuration has excellent strength and has a weight less than conventional guide bars of comparable size.
