A link plate for silent chains includes a pair of teeth, each formed of an inside
flank and an outside flank and a pair of pin apertures. A moment of force around
a pin M=FLo, where F is a force applied by a sprocket tooth against the outside
flank, and Lo is a length of a perpendicular drawn from a center O of a pin aperture
to an action line of the force, is decreased by decreasing Lo. The link plate engages
a sprocket tooth on an intersection between a straight line n and a flank, line
n and the direction of a central line connecting each O forming a pressure angle
, and contacting a circle having a center O and a radius r0.25P,
where P is a pin aperture pitch. Also, of the outside flank satisfies an
inequality, 3234, to lessen the force.
