Abstract
A power transmission chain belt has a rocker joint to reduce power transmission loss and to reduce the surface pressure acting on the connecting pin while maintaining bendability of the entire chain. The chain is formed of multiple inner links, each having a pair of pin apertures. The links are interleaved in the transverse and longitudinal directions and are connected by connecting pin inserted in pin apertures. The connecting pin includes a center pin. Arranged at the center of pin aperture are curved faces of which at both of its ends contact pulley friction surface and of a pair of rocker pins, which are arranged on both sides of center pin in the pin aperture and which are shorter than the center pin. In addition, the outer link is arranged on the outside of outermost inner link and step part of center pin is press-fitted into a pair of pin apertures in outer link.
