Abstract
A snow sweeper roller is mountable on a streetcleaning vehicle so that it is suspended and is vertically swingable and rotatable about a horizontal longitudinal shaft capable of being set oblique to the lengthwise direction of the vehicle on its under side. To avoid damage to a curb-end bearing of the sweeper roller, the bearing is provided with a guard on the outside of which has a forward cone converging towards the axis of the bearing shaft. The guard is mounted centrically rotatable on a cover of the bearing of the sweeper roller.
