  • Publication number: 20120065010
    Abstract: [Issue] To allow deviation of a chain to be reliably restricted during travel, and also to allow friction loss to be easily reduced when the chain is operating. [Means of Resolution] A guide plate 4 is disposed on the outermost side in the width direction of a silent chain 1 comprising link plates 2 which are pivotably linked by means of linking pins 3. The guide plate 4 has a pair of pin holes 41 into which the linking pins 3 are inserted, and also has side end parts 42 which are disposed at both ends in the longitudinal direction thereof, and an upper end part 43 and a lower end part 44 which link the side end parts 42 in the longitudinal direction. The upper end part 43 and the lower end part 44 are formed with a tapered transverse section, and become steadily thinner toward the tip end.
