Abstract: Disclosed is a dust suction apparatus includes: an upper plate 110 forming an upper part of a housing, which includes a plurality of suction ports 111 formed therein at a predetermined interval, and is connected with a vibration device 300 so as to be horizontally vibrated; a lower plate 130 forming a lower part of the housing and including a stepped portion formed on an inner side wall along an upper edge portion thereof so as to have the upper plate placed thereon, such that a storage space for storing the dust which has fallen down through the suction ports 111 is defined between the upper plate 110 the lower plate 130; and elastic actuating members 120 disposed between the upper plate 110 and the lower plate 130 to selectively open the suction ports 111 while normally closing the suction ports by elastic force stored therein.
