ツジあさり分け構造。[Scope of claim for utility model registration] A cutting center link 1 having a plurality of cutting edges, a pair of side links 2,
A saw chain C, which is pivotally connected with a pin via 2, is stretched endlessly over the groove on the circumference of the guide bar 3, and the chain sprocket 4 is engaged with the bottom recess of the center link 1 and driven to rotate. In the chainsaw M, the first blade of the plurality of cutting edges 11 on each cutting center link 1 starts from the center of the cutting center link 1,
A cutting edge shaving structure characterized in that the front and rear adjacent center links 1 and 1 are slit in opposite directions so as to clear the entire cutting width of the chain saw so as to be left-right symmetrical with each other. . The first blade of the cutting edge starts from the center, while the last blade ends at or near the center, and the cutting edge is divided so that the last blade of the front center link 1 is continuous with the first blade of the subsequent center link 1. The cutting edge scavenging structure as described in the above item.
