Zusammenfassung:	The present invention relates to a washer for tightening a chain sprocket of an excavator, and more specifically, to a washer for tightening a chain sprocket of an excavator as a tightening washer to connect the chain sprocket of the excavator and a driving reducer for the excavator when combining a bolt. The washer forms a penetration hole in which a tightening bolt passes through up and down on a center part and is made up of a square body. According to the present invention, fastening force can be improved by changing a shape of washer and a structure of a washer installation part of the chain sprocket used when binding the bolt for connecting the driving reducer of the excavator for construction machinery and the chain sprocket. Also, slip phenomenon of the bolt is prevented and bolt loosening caused by improved fastening force can be prevented when binding the bolt.
