ABSTRACT:
A saw chain for a motor-driven chain saw (1) is formed from center drive links (10) and lateral connecting links (11). A first radius (18) is the maximum distance of the axis (22) of the leading rivet opening (12) to the region (19) facing toward the forward running surface and lying in the running direction. A second radius (20) defines the maximum distance from the axis (23) of the trailing rivet opening (13) of the connecting link (11), which is next adjacent in the running direction (8), to the region (21) of the connecting link (11). The region (21) lies facing toward the rearward running surface (17) opposite to the running direction (8). The second radius (20) is greater than the first radius (18) and the sum of first radius (18) and second radius (20) corresponds approximately to the distance (b) of the axes (26, 27) of the rivet openings (24, 25) of a drive link (10) arranged between the connecting links (11).
