The present invention relates to a fan capable of preventing degradation in productivity while reducing high-frequency noise generated during the operation of the fan, the fan comprising: a fan hub having one open side; a rotor inserted and bolted in the fan hub; and a damping portion which is disposed between the inner surface of the fan hub and the outer surface of the rotor and reduces vibration and high-frequency noise during operation by coming into contact with the fan hub and the rotor. La présente invention concerne un ventilateur capable d'empêcher la dégradation de la productivité tout en réduisant le bruit haute fréquence généré pendant le fonctionnement du ventilateur, le ventilateur comprenant : un moyeu de ventilateur ayant un côté ouvert ; un rotor inséré et boulonné dans le moyeu de ventilateur ; et une partie d'amortissement qui est disposée entre la surface interne du moyeu de ventilateur et la surface externe du rotor et réduit les vibrations et le bruit haute fréquence pendant le fonctionnement en entrant en contact avec le moyeu de ventilateur et le rotor. 본 발명은 팬의 동작시 발생하는 고주파 소음을 저감하면서도, 생산성 저하를 방지할 수 있는 팬에 관한 것으로, 일측이 개방된 형상의 팬 허브, 상기 팬 허브에 삽입되어 볼팅되는 로터 및 상기 팬 허브의 내면과 상기 로터의 외면 사이에 배치되어 상기 팬 허브 및 상기 로터와 접촉해 동작시 진동과 고주파 노이즈를 저감시키는 댐핑부를 포함하는 것을 특징으로 한다.
