摘要：PROBLEM TO BE SOLVED: To provide a roller chain, a sprocket and a roller chain transmission device, capable of emphasizing a desired sound. SOLUTION: This roller chain (60) is constituted by connecting a plurality of links meshing with a sprocket. The roller chain is characterized in that the plurality of links include a large pitch link of a large pitch and a small pitch link of a small pitch, and at least one of the large pitch link and the small pitch link is periodically arranged. According to this roller chain, at least one of the large pitch link and the small pitch link is periodically arranged. Thus, when the roller chain meshes with the sprocket, the meshing forcing power of the roller chain and the sprocket can be periodically changed. As a result, the desired sound can be emphasized.
