A plate-link chain for a motor vehicle drive system including conical pulleys. The chain includes a number of link plates hingedly connected with each other by rocker members. The rocker members extend transversely to the longitudinal direction of the chain and within openings in the link plates. The rocker members and link plates bear against each other along curved contact surfaces to transmit power. Rocker member pairs roll against each other on facing curved rolling surfaces at a contact point that moves from an upper area above the center of mass of the rocker member cross section to a lower area below it. The ratio of the distance from the end of the upper area to the center of mass and the distance from the end of the lower area to the center of mass lies in a range of from about 1.1 to about 2.
