Claims

[Scope of utility model registration request]

A bell mouth disposed inside the main body casing includes a cylindrical part into which the fan is inserted, and a shield that protrudes from the outer periphery of the cylindrical part and blocks a passage between the outer periphery of the cylindrical part and the inner periphery of the main casing. The shielding wall has a structure in which a cutout is provided in a part of the shielding wall, and the cutout and the inner periphery of the main body casing are connected to an exhaust passage that communicates the inside and outside of the cylindrical part. A grille is attached to the indoor opening of the main body casing, and an intake port communicating with the intake passage is formed in a part of the side wall.
A simultaneous intake/exhaust type ventilation fan characterized in that a side wall of another part is provided with an exhaust port that communicates with the exhaust passage.
