PURPOSE:To facilitate the quipment of a brush body by allowing the maintenance operation surface side plate of an assembly to be attached and detached freely, providing a rubber band around a brush rotating shaft which projects to the internal surface of the opposite-side side plate, and fitting a tapered annular spring to the internal surface of the maintenance operation surface side plate. CONSTITUTION:Prior to operation, a maintenance operation side plate 2 is detached firstly and the hollow core of a brush body is inserted loosely into a guide shaft 5 and further intruded as it is to abut on a rubber band 7. Then, the side plate 2 is fixed with a screw to intrude an annular spring 8 to the opposite end of the hollow core, and consequently the expanded part of the spring 8 comes into excellent tight contact with the internal surface of the hollow core; and the side plate 2 is further clamped to the enclosure to press the hollow core to left with a spring 9, and consequently the rubber band 7 and hollow core circumferential edge are brought into press contact with each other, thus completing brush equipping operation. |
