초록

A chain component which has a simple surface treatment structure and in which satisfactory wear resistance is maintained for a long term; and a chain which employs this chain component so that a satisfactory wear elongation resistance is maintained are provided. A roller chain serving as an industrial chain for power transmission is constructed such that a pair of outer plates linked by two pins and a pair of inner plates linked together by two bushes onto each of which a roller is fit are alternately linked together in a plurality in a state that each p...
