ABSTRACT:
In a sprocket buffer, in order to reduce a noise and a shake/vibration of the chain gearing mechanism, an elastic band is provided to be adhered in a bottom of the sprockets; a cylindric pin which is to be inserted into the coupling hole in the bottom of the sprockets is formed in a lower part of the elastic band, and a pressure portion having the same diameter as that of the coupling hole is formed integrally with the cylindrical pin at a lower portion of the outer peripheral surface of the pin, thereby improving a durability against a cut off of the pin head portion.
