PURPOSE:To eliminate dropping of oil adhered to a decorative frame of a ventilator from the frame even if the ventilator is operated without mounting a filter body at the frame. CONSTITUTION:When a ventilator is operated without mounting a filter body 8 at a decorative frame 7 of the ventilator, an outer frame 10 and a thin part 21 of a lower end of a support beam are cut by a cutter, a lower end of a sheetlike filter 11 is cut, and an oil receiver 19 is separated. Then, the receiver 19 is mounted at a lower part of the front surface of the frame 7. Since oil adhered to and flowing down on a front surface of the frame 7 is received by the receiver 19, it is not dropped from the frame 7. |
