Abstract
In a silent chain, guide plates are U-shaped so that they can deform when tension is applied to the chain, thereby avoiding deformation of the connecting pins of the chain and warping of the guide plates. When the chain is unloaded, the frontmost edges of front pin holes of intermediate link plates of each link row are located forward of the frontmost edges of the front pin holes of the guide plates of the same link row, and the rearmost edges of the rear pin holes of the intermediate link plates of each link row are located rearward of the rearmost edges of the rear pin holes of the guide plates of the same link row.
