Claims

[Scope of claim for utility model registration] A pin link in which both ends of a pin link plate are connected and fixed by pins, and both ends of a roller link plate are connected and fixed by bushings, and furthermore, a roller body and an elastic ring are arranged side by side on the bushings. In the noise prevention roller chain, the elastic ring has a substantially rectangular cross section, and the elastic ring has a substantially rectangular cross section, and the elastic ring has a substantially rectangular cross section. In addition, the outer diameter of the elastic ring is configured to be larger than the outer diameter of the roller body so that the roller chain comes into contact with the sprocket first when the roller chain engages with the sprocket, and the length of the contact surface of the outer peripheral surface of the elastic ring with the sprocket is A noise prevention roller chain characterized in that the length is shorter than the length of the contact surface with the bushing on the inner peripheral surface.
