Abstract
With a view to suppressing fretting in a power transmission chain, when a chain straight-line area is seen from a chain widthwise direction W, a flat portionof a first pinof the chain extends in an inclination direction D. A point of intersection Pis formed by an imaginary line Lwhich passes through a center position of an overall height h of the first pinalong the inclination direction D intersecting the flat portion. A point of intersection Pis formed by an imaginary line Lwhich passes through a contact portion Aand which extends in a chain advancing direction X intersecting the flat portionbetween the point of intersection Pand one end Pof the flat portion. When assuming that a distance between the point of intersection Pand the point of intersection Pis referred to as hand a distance between the point of intersection Pand the one end Pof the flat portionis referred to as h, 0.1·h≦h
