[Scope of Claim for Utility Model Registration] (1) A sound deadening chamber having a connection port for connecting to a ventilation duct on one side and a grill mounting opening on the bottom side, and a sound damping chamber installed in the grill mounting opening of the sound damping chamber, The silencing chamber has a rim that forms a ventilation opening in the room, and the silencing chamber has a ventilation flow flowing between the opening of the connection port and the grille mounting opening on the side of the connection port opening or the grille mounting opening. A wind direction plate with holes for guiding toward the opening side is provided obliquely or in an arc shape so as to form an air layer between the outer shell of the sound deadening chamber, and is formed by the wind direction board and the inner surface of the sound deadening chamber. This noise-absorbing ventilation grill features a sound-absorbing material attached to the inner surface of the ventilation duct. (2) The connection port is made of a sound-absorbing tube made of glass wool with a cross-covered inner surface on the side of the ventilation path through which the ventilation flow passes;
Consisting of a cover member that covers the outer periphery of this sound-absorbing tube, a connecting member that connects one end of the cover member to the sound-deadening chamber, and a connecting pipe that connects the other end of the cover member to the ventilation duct. The noise-reducing ventilation grille according to claim 1, characterized in that: (3) The end face of the sound-absorbing tube on the sound-deadening chamber side is covered by the inner fitting of a bar-ring-like part formed in the opening of the sound-deadening chamber, and the end face of the sound-absorbing pipe on the side connected to the ventilation duct is covered with a bar-ring-shape part formed at the end of the connecting pipe. 3. The noise-reducing ventilation grille according to claim 2, characterized in that it is coated with.
