The belt lifter is provided with a tubular shaft portion pivotally mounted in the forward wall of the floor nozzle housing and a transparent plastic cup shaped member positioned within the tubular shaft section in which the end wall provides the viewing window. A face plate is keyed to the tubular shaft section to rotate the belt lifter for connecting and disconnecting the belt. A pair of triangular shaped snap rings secure the belt lifter assembly in its assembled position.
