The holding means 31 includes frame bodies 32a-32d which are arranged radially to an outer direction from a center and are mounted so as to be bridged on the intake port 54. The fixing means 43b and 43d include attracting means 46b and 46d which are respectively structured of magnets and yokes. Thereby, the holding means 31 with the filter 21 held thereon is fixed to a front surface part 53 of the Sirocco fan 52 of which an outer surface is formed of magnetic material by magnetic force of the fixing means 43b and 43d arranged on the frame bodies 32b and 32d. |
