Abstract
A rocker pin for use in a power transmission chain has an identifying mark for distinguishing the rocker pin from another rocker pin having a different thickness or a different rocker surface. The identifying mark may include a groove, ridge, colored mark, lustrous streak or the like provided on a peripheral surface except a rocker surface in the longitudinal direction of the rocker pin. The rocker pin having such identifying mark can be visually identified with ease so that the rocker pin is prevented from being mixed with a different kind of rocker pins. This enables easy and confusion-free storage of the rocker pin and prevents incorrect combination of a longer pin and a shorter pin, which may occur when they are used in combination to form a single rocker joint.
