Abstract
A power transmission chain () has links (), pins (), and interpieces (). The links () each have a front and a back insertion parts () through which the pins are inserted. The pins () and the interpieces () connect links () that are arranged side by side in the lateral direction of the chain such that the front insertion part () of one of the links () and the rear insertion part () of the other link () correspond to each other, and the connection is made such that that the links () are bendable in the longitudinal direction. The locus of a contact position of a pin () and an interpiece () is an involute of a circle. Two or more kinds of sets of a pin () and an interpiece () having different radii of base circles of involutes are formed, and these sets of a pin () and an interpiece () are randomly arranged.
