The rail includes two guide arms (722), a closed end portion (724) which connects the guide arms to each other, and wings (723) extended from free end portions of the guide arms. A groove (711) of the brush accommodates the guide arm (722). The fixation unit includes a first fixation unit (A) and a second fixation unit (B). The closed end portion (724) of the guide rail (72) is joined to the first fixation unit (A). The second fixation unit (B) includes tow posts (4) which are separated from each other. Each post defines a slot (41) on an upper end portion. A protrusion (42) is extended from each slot (41) and locks the wing (723) in the slot. |
