Abstract
A power transmission chain having a plurality of links, with each link having a pair of apertures. The links are connected by rocker pins inserted in the apertures. The radius of curvature of a convex rocker contact surface of a pair of rocker pins is from approximately 0.6 to 1.6 times the pitch of the chain. In another embodiment, each of the rocker pins includes an arc-like rocker surface, a seat surface, and a flank surface that connects the above two. The aperture includes an arc-like support surface that supports the seat surface and side surface and is located with certain clearance from the flank surface. Also, the chain pitch line is located within the aperture seat surface.
