Abstract
The disclosed invention relates to an adaption of a conventional conveyor driving roller whereby the driving force frictionally transmitted from a rotating shaft to the article conveying roller is maintained even under conditions wherein oil or water enters between the frictionally engaging surfaces. Specifically, a pressure plate is provided at one end face of the roller which is spring biased for frictionally engaging that roller end face. Provision is made for adjustment of the degree of compression of the pressure plate biasing spring so that the degree of frictional force between the pressure plate and the roller end face may be varied.
