PROBLEM TO BE SOLVED: To provide a blind capable of compensating for an error of a rotation angle of a slat, which occurs by inserting a middle stage cord into a notched part formed at a side edge of the slat.SOLUTION: When a rotary drum 32 is in a reference angle position which is an angle position assumed when a slat 18 is in a horizontal state, a cross-sectional shape of a peripheral surface of the rotary drum 32 assumes a shape asymmetrical with respect to a vertical plane. When the rotary drum 32 is in the reference angle position, height positions of connection points 16f and 16g between vertical cords 16a and 16b and a middle stage cord 16c of a ladder cord 16 are different from each other in the front and rear vertical cords. |
