Abstract
A roller conveyor has rollers mounted on laterally-spaced side frames by brackets that have a frame attachment opening extending through a base portion of the bracket, and a roller shaft end receiving aperture extending through a flange portion of the bracket. The shaft receiving aperture is aligned at an oblique angle with respect to the frame attachment fastener opening such that when a fastener is inserted through the frame attachment opening and the bracket installed on a respective side frame, the shaft receiving aperture becomes misaligned with the end of the roller shaft to an extent sufficient to lock the shaft end in fixed relationship with the bracket and maintain a bias force on the fixed connection between the shaft receiving aperture of the flange and the roller shaft end.
