A guide plate a for silent chain is substantially arch-shaped and has a pair of pin holes formed therein at a position adjacent to opposite free ends of the arch-shaped guide plate. The arch-shaped guide plate further has an arcuate inner peripheral surface and an arcuate outer peripheral surface both extending arcuately about a center located at the midpoint of a pitch line segment interconnecting the pair of pin holes. The arcuate inner peripheral surface has a radius of curvature which is in the range of 35 to 45% of the chain pitch, and the arcuate outer peripheral surface is blended with the opposite free ends of the arch-shaped guide plate.
