PROBLEM TO BE SOLVED: To provide a power transmission chain and a power transmission device preventing fretting caused by relative sliding of a pin to a link when a load repeatedly acts on. SOLUTION: Linear relative sliding preventing parts 22, 23 sandwiched between curve portions are formed at the upper and lower edge parts of the pins 14, and linear relative sliding preventing parts 26, 27 sandwiched between curve portions are also formed at the pin fixing parts 18 of the rear insertion parts 13 of the corresponding links 11. Similarly, linear relative sliding preventing parts 24, 25 sandwiched between curve portions are formed at the upper and lower edge parts of inter pieces 15, and linear relative sliding preventing parts 28, 29 sandwiched between curve parts are also formed at the inter piece fixing parts 17 of the front insertion parts 12 of the corresponding links 11.
