PROBLEM TO BE SOLVED: To form an end face shape of a split pin so that a pin width variation by rotation of the pin is minimized, reduce a polygonal effect and sliding of the pin to a sheave, and reduce noise and power loss. SOLUTION: In this endless belt connecting link plates by a pair of the split pins and holding two blocks between the pins, end faces of the pins are formed in round shapes in a belt longitudinal direction (an X direction). A deviation amount aA of a radial center of the round shape to a pin rotational center is determined by distributing the pin width variationμso that the variation is equal on a positive rotation side and a negative rotation side of a rotation angleθin regard to a rotation angle variationηa within an application range.
