Abstract
In a silent chain transmission, the distance between the centers of front and rear pin holes of each of the inner link plates of the chain is smaller than the length of the smallest chord obtained by dividing, by the number of sprocket teeth, the circumference of a circle having a radius extending from the center of the sprocket to the center of a pin hole of a link plate of the chain when the last-mentioned link plate is fully engaged with the sprocket.
