ABSTRACT:
A vacuum cleaner brushroll including a tufted spindle supported by end assemblies having bearings that rotatably mount the spindle in the vacuum cleaner nozzle. The brushroll includes a spindle and improved end assemblies for supporting the spindle comprising a first member fixed to an end of the spindle, a relatively rotatable second member having a portion that is adapted to mate with mounting structure in the vacuum cleaner nozzle, a bearing which is supported by the second member and in turn supports the first member and stub shaft structure for coupling the first member with the bearing. Either the first or second member has a pair of annular walls that are radially spaced apart to define an annular channel, while the other member has an annular skirt that extends into the annular channel to form a labyrinth thread seal. The stub shaft structure may be integral with the second member and may include reinforcing shafts or inserts for strengthening the first member against bending due to the force of the drive belt.
