摘要： Provided is a chain of a chain saw. In a chin saw including a chain which cuts an object to be cut while being rotated in an infinite trajectory, the chain includes a drive link in which an abrasive is mounted on an upper portion thereof, a pair of side links which are fastened to connect neighboring drive links, and a connection pin which is mounted by passing through overlapping portions of the drive link and the side links. The drive link and the side links may absorb rotational friction so that a rivet can withstand well. By a technical configuration for simply replacing, removing and assembling the assembly of the drive link and side links which become loose, power transmitted to the drive link may be provided as cutting force as it is, thereby improving cutting efficiency.
