Abstract
A chain is provided with a plurality of links, and connecting members for connecting those links such that the links are relatively bendable to each other. A first pin of the connecting member is clamped between pulleys thereby to transmit the power between itself and said pulleys. The chain includes a central area with respect to chain width directions, and side areas located on the sides of the central area. In the central area, links adjoining in the chain width directions are pushed to contact with each other, and rotate relative to each other while exerting frictional forces on each other as the chain is bent. In each of the side areas, the links adjoining in the chain width directions are arrayed through a predetermined clearance.
