(54)	Vacuum cleaner with noise reduction device

(57) The present invention relates to a vacuum cleaner that can reduce noise due to discharging air. The vacuum cleaner includes a cleaner case inside which contaminants collector and fan motor are disposed; a discharging duct disposed inside the cleaner case in fluid communication with the fan motor, and the discharging duct having a substantially rectangular section with a length dimension of a long side more than twice of a length dimension of a short side thereof; and an exit formed at one end of the discharging duct in a direction perpendicular to a direction in which air flows inside the discharging duct; wherein air discharged from the fan motor is discharged outside the cleaner case via the exit of the discharging duct.
