The present invention relates to an automatic window opening and shutting device having a noise prevention structure which has a mount unit of a window on which an automatic opening and shutting device is installed and a sound absorbing pad attached to an inner circumferential surface of a cover to cover the mount unit to conceal the mount unit, and changes a material of a gear unit to transfer power of a motor to a structure and a material with low noise to reduce noise produced when driving the automatic opening and shutting device. The automatic window opening and shutting device is installed on any one among a window frame (10) and at least one pair of windows (20) on the window frame (10) to be slid to be opened and closed, and comprises: a drive motor (110) installed on any one window (21) among the windows (20); and a drive roller (120) which receives power of the drive motor (110) to be rotated, and is installed to allow an outer circumferential surface thereof to come in contact with one surface of an adjacently installed fixed window (23) to slide the window (21) to open and close the window (21). A component is installed on a mount unit (M) of a window sliding part (21a). A sound absorbing pad (21c) is attached to an inner circumferential surface of a cover (21b) mounted to enclose the mount unit (M) on which the component is installed to conceal the mount unit (M). 본 발명은 자동개폐장치가 설치되는 창짝의 마운트부 및 상기 마운트부를 덮어 은폐시키는 커버의 내주면에 흡음재 패드를 부착하고, 모터의 동력을 전달해주는 기어부의 재질을 소음 발생이 적은 구조 및 재질로 변경해줌으로써, 자동개폐장치의 구동 시 발생하는 소음을 줄일 수 있도록 한 소음방지구조가 적용된 창짝 자동개폐장치에 관한 것이다. 이를 실현하기 위한 본 발명은, 창틀프레임(10)과, 창틀프레임(10)에 슬라이딩 개폐 가능하게 설치되는 적어도 한 쌍의 창짝(20) 중 어느 하나에 설치되는 창짝 자동개폐장치에 있어서, 상기 창짝(20) 중 어느 하나의 창짝(21)에 설치되는 구동모터(110); 및 상기 구동모터(110)의 동력을 전달받아 회전되되, 인접 설치된 고정 창짝(23)의 일면에 외주면이 맞닿게 설치되어 상기 창짝(21)을 슬라이딩 개폐시켜주는 구동롤러(120);를 포함하되, 상기 제 구성요소가 설치되는 창짝 여밈대(21a)의 마운트부(M)와, 상기 제 구성요소가 설치된 마운트부(M)를 감싸도록 결합되어 은폐시켜주는 커버(21b)의 내주면에는 흡음재 패드(21c);가 부착된 것을 특징으로 한다.
