CONSTITUTION:The first guide rail 4c and the second guide rail 4d are integrally formed at a supporting part 4 and the first guide rail 5b and the second guide rail 5c are integrally formed at a supporting member 5, respectively, so that the supporting members 4 and 5 are fixed to a rear surface of a suction grill 1 and the two guide rails can be fixed at once. In addition, the first guide rail 4c and the second guide rail 4d are disposed at the supporting member 4 and the first guide rail 5b and the second guide rail 5c are disposed at the supporting member 5, respectively, so that the first filter 15 and the second filter 2 can be separately inserted and guided. |
