とができる。According to the above-described air purifier 40, both wall surfaces of the case portions 8 and 9 forming the air storage portion 3 are regulated at intervals by the support members 10 and 11, and penetrate the support members 10 and 11 in this regulated state. Since the bolts 12 are tightened and fixed, the rigidity of the wall surface can be increased as a whole. Moreover, since the fastening position by the bolts 12 is near the inlet side of the air supply duct 7 through the support members 10 and 11, wall vibration in the vicinity of the inlet of the air supply duct 7 where a large negative pressure is applied is effectively suppressed. be able to. Further, as in the embodiment, by making both the wall surfaces fastened with the bolts 12 curved outward, the rigidity of the whole wall surface can be further enhanced.

好ましい。In the above embodiment, the support members 10 and 11 are the case portions 8 and 9.
It is integrally formed on the wall surface of the, but as shown in FIG. 4, this is one spacer 1 independent from the case parts 8 and 9.
It may be replaced by 3. However, from the viewpoint of improving the assemblability, this supporting member is
It is preferable to integrally form the case portions 8 and 9 as in the embodiment shown in FIG.
また、実施例では、支持部材10,11が１個所だけであ
