<p>The present invention relates to a roll blind which can easily adjust the amount of transmitted light regardless of the position of a roll screen, be easily manipulated, and have high reliability. The roll blind includes: a roll screen in which a first screen overlaps with a second screen; a winding rod around which the roll screen is wound; a first driving gear rotating the winding rod; a friction rod contacting the roll screen to push the first or the second screen upward by a frictional force therebetween so that the first and second screens are dislocated with respect to each other; a control rod driving the friction rod in rotation; and a switch part blocking the transmission of power between the friction rod and the control rod when the winding rod rotates.</p> |
