Abstract:
1. A silent chain comprising a plurality of links each having a pair of tooth parts which mesh with sprockets and a pair of pin holes are arranged in a series of rows in a lengthwise direction with the links in each row stacked in a thickness direction, the rows of links being linked so as to be able to pivot about one another by linking pins which are inserted into the in holes, wherein: guide links are provided for guiding the silent chain on the sprockets when the silent chain meshes with the sprockets, the silent chain made up of alternate guide link rows and non-guide link rows with the guide links provided on the outermost ends of each guide link row; sliding plates are provided only in the guide link rows, the sliding plates have a pair of pin holes into which the linking pins are inserted, and also have a back surface part which has a first back surface height that is greater than a second back surface height of the links and comes into contact with a tensioner arm or chain guide; and the sliding plates do not have tooth parts which mesh with the sprockets so that when the plurality of links pivot, the tooth parts of the plurality of links in the non-guide link rows do not slide against the sliding plates, wherein the pin holes in the sliding plates are larger than the pin holes in the plurality of links, and the pin holes in the sliding plates have a clearance fit with the linking pins, wherein the pins do not rotate relative to the sliding plates in spite of the clearance fit.
