The sprocket includes the sprocket body formed with a plurality of teeth on a circumferential surface thereof, and the cushion ring provided to at least one side face of the sprocket body and having an outer circumferential surface that makes contact with link plates of a chain. The cushion ring is secured to the sprocket body without an adhesive layer.
