ABSTRACT:
A method of manufacturing of power transmission chain1by interconnecting plural link plates2with pins3. Individual pin pairs3are arranged and temporarily fixed to places. The link plates2are sequentially stacked in layers by press-fitting respective through-holes4of the link plates2about the respective pin pairs3, whereby the link plates2are interconnected to form a circular chain (an endless loop). Subsequently, the individual pin pairs3are released from the temporarily fixed state. Thus, the manufacture of the power transmission chain1is decreased in the number of operation steps, so that the chain may be assembled easily.
