If the adjustment line is not operated after the rotation, the reverse rotation of the inner rotating body is prevented, and the blind sheet is prevented from being loosened.

이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 한정되는 것이 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위내에서 여러가지 치환 및 변경이 가능하다는 것이 본 발명이 속하는 분야에서 통상의 지식을 가진자에게 있어서 명백할 것이다.The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various permutations and modifications can be made without departing from the spirit of the present invention. It will be obvious to him.
