An article transporting conveyor roller having a frictional drive transmission component as the last link between the drive power source and the live portion of the roller. The frictional surface of the drive component extends around the entire inner surface of the live portion of the roller so as to provide a true linear relationship between the weight of the article conveyed and the frictional force of the drive component. The frictional drive transmission component allows the live portion of the roller to stop moving in the event of accumulation of the articles to be transported.
