ABSTRACT:
There is provided a duster which is suitable for cleaning. To prevent a brush wound around a rod from slipping in the direction of the length and the direction of the axial rotation of the rod, the duster comprises: a number of sharp protrusions formed on a portion of the rod around which the brush is wound, so that a stitched portion of the brush is stuck to the sharp protrusions to semi-permanently prevent the slip of the brush, thereby maintaining the product to be like a first assembled state thereof, preventing the function of the duster from being deteriorated, and preventing the surface of an object to be cleaned from being scratched by the rod which is partially exposed. In addition, since the slip of the brush is prevented by using no adhesive agent, the product is easily assembled and the cost is greatly reduced accordingly.
