Abstract

The invention proposes an air exhaust device. To prevent the creation of abnormal noise. The air exhaust device (101) is an air exhaust device constructed to exhaust indoor air from the inside out of the room. The air exhaust device (101) consists of a casing (12) and a blower (13). The casing (12) includes the first inlet port (12a) formed on the top surface of the casing. The blower (13) is contained in the casing (12). In the plan view, the first inlet port (12a) is positioned closer to the first side surface (Sl) of the casing. The machine (13) is positioned closer to the second bending surface (S2) of the shell (12). The second bending surface (S2) of the shell (12) is the surface opposite to the first bending surface (S1).
