POWER TRANSMITTING CHAIN AND POWER TRANSMISSION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a power transmission chain and a power transmission device capable of optimizing stress generated in a link and capable of reducing the development man-hour. SOLUTION: The link 11 is provided with a front side pillar part 20 on a front side of a front insertion part 12, a rear side pillar part 22 on a rear side of a rear insertion part 13, and an intermediate pillar part 21 between the front insertion part 12 and the rear insertion part 13. A minimum width of the front side, the rear side and the intermediate pillar parts 20, 22 and 21 is made equal, and the minimum width Q of the front side, the rear side and the intermediate pillar parts 20, 22 and 21 satisfies the following relationship; 0.2P
