摘要： Projections colliding with constricted portions at the center of hourglass-shaped pin link plates and with constricted portions at the center of hourglass-shaped roller link plates are provided at an annular resilient body. When a roller chain starts to mesh with a sprocket, constricted portions at the centers of hourglass-shaped link plates of the roller chain can be pushed radially outwards from the sprocket by the projections of the resilient body, vibrations occurring at the roller chain meshing with the sprocket can be made small, vibrations at each part of the roller chain can be made small, collision speed when rollers of the roller chain collide with teeth bottoms of the sprockets can be reduced, and the generation of noise can be suppressed. Moreover, because hourglass-shaped link plates are used, the roller chain can be made lighter than when flat oval shaped or oval shaped link plates are used.
