Abstract:
A low-noise roller chain for use with a sprocket, comprising:a hollow cylindrical bushing;a pair of inner plates connected to opposite ends of said bushing, respectively;a roller fitted on said bushing and having opposite ends facing inside surfaces of said inner plates; andan elastic member covering at least part of at least one of an inner peripheral surface and an outer peripheral surface of said roller and having a pair of projecting portions projecting beyond said opposite ends of said roller in an axial direction of said roller, the roller having an overall axial length which is less than an overall axial length of the elastic member, said elastic member being elastically deformable to move said projecting portions into pressure contact with said inside surfaces of said inner plates, respectively, for preventing collision of said roller with said inner plates when said roller chain and said sprocket are engaged together.
