気扇。 A blower is housed within a cylindrical body frame that forms a ventilation path, a grill is attached to the indoor side of the body frame, and when the blower is operated, indoor air is sucked through the grill and exhausted to the outside. When the air passage is supported within the body frame and wind pressure is present, the air passage is closed by the wind pressure to open the air passage, and when the wind pressure is not present, the air passage is opened by the force of a spring to open the air passage. A ventilation fan characterized in that a blocking shield is disposed between the grille and the blower.
