Abstract

PROBLEM TO BE SOLVED: To mount/demount an air filter easily without removing a suction grille by employing an elastically deformable air filter. SOLUTION: Means for deforming an air filter 7 elastically in the direction perpendicular to the inserting/removing direction comprises a filter guide section formed of an elastic synthetic resin into a stripe, and a filter fixing section having corrugated cross-section and jointed, at the lower end thereof, to the filter guide section. Consequently, the air filter 7 can be easily deformed elastically in the direction perpendicular to the inserting/removing direction when it is inserted into an inserting/removing port. The air filter 7 can thereby be fixed to the inner face side of a suction griller 5 and removed therefrom easily. When a side wall is provided at the filter fixing part constituting the air filter 7 in order to block suction air supply from the opposite sides, the air sucked through a suction port 8 passes through the air filter 7 effectively.
