The silent chain is made up of guide plates arranged inside in the chain width direction; link assemblies, at least one of which is arranged on both outsides of the guide plate; and outer link plates further arranged on outermost sides, and they are assembled in an interlinked manner and connected by connection pins freely bendable. The link assembly has a unified structure in which at least two inner link plates having a pair of teeth that engage with the sprocket teeth are connected by a pair of bushings. The sprocket thereof has a groove capable of inserting the guide plate being arranged inside in the silent chain width direction, and formed with a ring shape inside of an outer circumference width direction.
