Abstract
A rocker pin type continuously variable transmission chain comprising a plurality of link plates connected endlessly by paired rocker pins, each of the load transmitting surfaces of each rocker pin insertion bore having an arcuate portion, opposing the planar portion of each rocker pin, with a radius of curvature greater than that of the convex portions of the rocker pins to prevent rotation of the rocker pins in the bores, whereby load forces are transmitted by extensive surface contact areas.
