A both-side meshing type silent chain is provided which not only permits improvement in durability of a tensioner and a chain guide, but also permits a high-speed and smooth transfer of power. The both-side meshing type silent chain has a high durability and includes a plurality of articular train plates and a plurality of guide train plates. Each of the plurality of articular train plates and the plurality of guide train plates have main teeth for engagement with a sprocket disposed on an inner peripheral side of a chain. The plurality of articular train plates are alternately connected to the plurality of guide train plates with pins. Guide plates, which are guided by side faces of the teeth of the sprocket, are disposed on both outer sides of each of the plurality of guide train plates. Rear faces of the guide plates, which constitute a part of each of the plurality of articular train plates, the plurality of guide train plates, and the guide plates, and which are arranged in the longitudinal direction of the chain, are formed as flat faces. The rear faces, of a remainder of the plurality of articular train plates and plurality of guide train plates, are formed with sub-teeth for engagement with a sprocket located on an outer peripheral side of the chain.
