Abstract
A supporting roller assembly for a household appliance includes a fixed rear roller and a height-adjustable front roller. The front roller has a frame for mounting against a flat surface on the underside of the appliance, together with a vertically extending front wall at the front of the appliance mounting the head of an adjustment screw. The roller is carried on a roller carrier which is pivotally mounted on the frame member and carries a captive nut engaging the screw so that rotation of the screw causes the roller carrier to rotate about its pivotal engagement to raise and lower the front end of the appliance. The fixed rear roller assembly has a frame which snaps into an opening in a bottom wall of the appliance. The bottom wall has upwardly projecting flanges which overlay a press-in axle carried by the roller frame and journaling the roller and the flanges prevent any lengthwise movement of the axle which would cause it to disengage from the ears on the frame.
