摘要

The brush unit (1) is firmly clamped in its holder and is used for clearing roads, pavements and similar. It comprises a number of brush bodies (20) set in a holder (10). In particular, the brush bodies extend outwards through holes in the holder. During the manufacturing process, a firm connection between the holder and the brush body is formed and exerts pressure forces on the holder, which narrows the holes, causing the brush bodies to be firmly clamped in the holder.
