Provided is a cordless blind apparatus, which can be conveniently operated without using a cord. The cordless blind apparatus comprises: a winding roll coupled to a rotary shaft; a screen member wound or unwound by the winding roll; a weight member connected to a lower portion of the screen member to apply torque in the first direction in which the screen member is unwound from the winding roll by gravity; an elastic member applying an elastic force to the winding roll so as to apply the torque in the second direction in which the screen member is wound; and a friction member increasing frictional resistance of the winding roll at an inner side of the winding roll.
코드 없이 편리하게 작동시킬 수 있는 코드리스 블라인드장치가 제공된다. 코드리스 블라인드장치는, 회전축에 결합된 권취롤, 권취롤에 권취(winding)되거나 권출(unwinding)되는 스크린부재, 스크린부재의 하단에 연결되어, 중력에 의해 권취롤에 스크린부재가 권출되는 제1방향으로 토크를 인가하는 웨이트부재, 권취롤에 탄성력을 가하여, 스크린부재가 권취되는 제2방향으로 토크를 인가하는 탄성부재, 및 권취롤의 내측에서 상기 권취롤의 마찰저항을 증가시키는 마찰부재를 포함한다.
