A silent chain is provided with strength and elongation of respective link rows made uniform, elongation of every link made equal regardless of elastic and/or plastic deformation, and inexpensive production cost. The silent chain includes a first link row, a second link row, a connection pin and a pin stopper. Each of the first and second link rows consists of a guide plate and the same number of link plates whose shapes and sizes are the same. The first and second link rows are staggered in the longitudinal direction of the chain, and connected in alternating, interleaved relationship by connection pins. The guide plates and the link plates of the first and second link row are relatively rotatable to the connection pins. The first and second link rows are alternately arranged in mirror image symmetry.

1. Field of the Invention
The invention relates to a silent chain wound on a pair of sprockets that are apart from each other to transmit power from a drive sprocket to a follower sprocket.
2. Prior Art
FIG. 1 is a plan view showing a portion of an embodiment of a silent chain according to the invention.
FIG. 2 is a front elevational view of the chain portion of FIG. 1.
An embodiment of the silent chain according to the invention will be described with reference to the drawings. Typical uses of a silent chain are in an engine for automobile, in a transmission for an automobile and in a transfer for an automobile. In such uses, the silent chain is wound in an endless loop around a pair of sprockets that are spaced apart from each other, and transmits power from a drive sprocket to a follower sprocket.
The silent chain 10 basically includes: first link rows 20; second link rows 30; connection pins 12; and pin stoppers 14.
Each first link row 20 consists of a guide plate 22 and three link plates 24. Each link plate 24 has the same shape and size. Each second link row 30 consists of a guide plate 32 and three link plates 34. Each link plate 34 has the same shape and size.
