Abstract
A chain cover is provided which can be mounted on a general-purpose roller chain, can be attached and detached to and from the chain, and will not impair bendability of the chain. Side covers for covering both sides of the chain extend from both ends of a top cover for covering a top of the chain. Each side cover has a shaft hole for receiving a coupling pin of the chain, a convex arcuate front edge that is concentric with the shaft hole, a concave arcuate rear edge opposed to the front edge, and a tapered guide surface. The top cover is supported directly by roller links of the chain to allow the coupling pin to be inserted not deeply into the shaft hole.
