The present invention relates to improvements in a ventilating apparatus installed in a ventilating hole in an outer wall to enable natural ventilation. The ventilating apparatus includes a sound deadening cartridge (10) installed in a ventilating hole (2) and a cap cover (20) detachably installed in an interior opening of the ventilating hole (2) and covering the sound deadening cartridge (10) and thus the interior opening of the ventilating hole (2), the cap cover (20) having an air outlet (24) through which introduced external air having passed through the sound deadening cartridge (10) is blown out into a room (4). The air outlet (24) is placed along a wall surface (8) to allow the introduced external air to flow out along the wall surface (8). The air outlet (24) may have a normally open portion (32) and an adjustment area (33) in which a control plate (30) is placed, the control plate opening and closing a part of the air outlet (24) so that the amount of air introduced can be controlled. Alternatively, the air outlet (24) may be normally open in all directions. |
