The brush member includes a brush base which has a generally U-shaped cross section, a rear section that straddles the distal open end portion of the pipe body and that has opposite lateral side portions pivoted respectively to two diametrically opposite positions of the distal open end portion of the pipe body, and a front section with a distal front end face. The brush member further includes a plurality of bristles provided on the front end face of the front section of the brush base. The brush base is pivotable with respect to the distal open end portion of the pipe body between a position of use, wherein the front section of the brush base extends frontwardly relative to the distal open end portion of the pipe body, and a storing position, wherein the front section of the brush base straddles the pipe body. The brush base can be retained releasably on the pipe body at the position of use and the storing position.
