Therefore, depending on the temperature and humidity inside the indoor unit Ui (see FIG. 2), moisture or dust may accumulate in the gaps of the hair of the brush 24b, or moisture may adhere to the shaft portion 24a due to condensation. . Furthermore, since the shaft portion 24a is made of metal, the axial length of the shaft portion 24a changes due to thermal expansion or contraction in accordance with a temperature change inside the indoor unit Ui. For example, when the temperature is high, the shaft portion 24a is thermally expanded, and its length becomes slightly longer.
