Abstract

In order to create a guiding rail (2) for chain saws which eliminates the recoil problem owing to its special shape and geometry without thereby in any way limiting the useability of the guiding rail (2) or of the chain saw equipped therewith, it is proposed, in the case of a guiding rail (2) for chain saws, that the tip part (20), which is located on the same side of the axis (18) as the inlet portion (12), has a small radius of curvature which is less than or equal to a quarter of the width (R2 </= 0.25 B) and the inlet portion (12) merges into this tip part (20) via an inlet slope (22) which leads tangentially into this tip part (20) and forms an acute angle alpha with the axis. <IMAGE>
