ABSTRACT:
A chain capable of diminishing noise and wear occurring at the time of engagement of the chain with a sprocket is provided. At least a portion of an inner surface of each inner plate, which comes into opposition to a side face of a tooth top of the sprocket at the time of engagement of the chain with the sprocket, is chamfered in a shape conforming to the contour of a side tooth form of the sprocket tooth top. Since a chamfered portion of an inner surface of each inner plate has a shape conforming to the contour of a side tooth form of a sprocket tooth top, the chamfered portion and the sprocket tooth top come into contact with each other smoothly in a state of face-to-face contact, so that the level of noise generated upon engagement of the chain with the sprocket can be reduced and it is possible to suppress the wear of the inner surface of the inner plate and that of the tooth top of the sprocket.
