PROBLEM TO BE SOLVED: To provide an air suction device for an air conditioner which can reduce the piping sound of the air blown out of a blowout port. SOLUTION: One end of a porous cylindrical silencing member 30 consisting of foamed material is connected to the blowout part 22 of a duct 2 for ventilation. The above silencing member 30 guides the air blown out of the blowout part 22 of the duct 2 for ventilation and suppressed the distrurbance of the air and prevents the occurrence of piping sound of air and also absorbs the piping sound generated in the vicinity of the blowout part 22 of the duct 22 for ventilation by means of the porous silencing member 30. |
