SOLUTION: When an air filter 7 is detachably attached to the internal surface of a suction grill 5, the filter 7 is inserted from an inserting and removing port of the grill 5 and, at the same time, guided to the internal surface side of the grill 5 by means of a filter guide 6 while the filter 7 is elastically deformed. In addition, the grill 5 is constituted in such a way that the inserting and removing port side of the grill 5 can come off while the end of the grill 5 on the opposite side of the inserting and removing port is locked when an excessively strong force is applied to the grill 5 when the filter 7 is removed. |
