<p>BRUSH STRUCTUREA rush structure includes a roller member (10), a sponge covering member (20), and a sponge axle member (30). Through connection portions (22) of the sponge covering member (20), an outer layer portion (21) and inner layer portions (23) of the sponge covering member (20) are firmly coupled to an outer wall of the roller member (10) and corresponding circumferential hole portions (12) of the roller member (10). When the roller member (10) is turned, the sponge covering member (20) is10 simultaneously driven so the roller member (10) won't be idling. The sponge covering member (20) won't disengage from the roller member (10) because of elastic fatigue, having a stable configuration and a long service life space.FIG 1</p> |
