PROBLEM TO BE SOLVED: To provide a double Roman shade of a drum-wound type, having a miniature size and manufactured at low cost. SOLUTION: Drums 3 and 4 are rotatably supported on a head rail 1. One end side of each of lifting up/down cords 5 and 6 is retained on each of the drums 3 and 4. The other end side is connected to each of curtain bodies C1 and C2. A rotary shaft 7 relatively rotatably penetrates through the drums 3 and 4 and is rotated/stopped by an operation part 8 provided on the one side. Drive members 13 and 14 of clutch mechanisms 9 and 10 are shifted by an operation part 8 to reciprocally shift between two positions of a connected position where the drums 3 and 4 are connected to the rotary shaft 7 and an unconnected position where the connection is released. Fixing members 17 and 18 of stopper mechanisms 11 and 12 are shifted by the operation part 8 to be synchronized with the clutch mechanisms 9 and 10 to reciprocally shift between two positions of a locked position where the drums 3 and 4 are fixed and an unlocked position where the fixation is unlocked. Alternate movements of the clutch mechanisms 9 and 10 and the stopper mechanisms 11 and 12 connect either of the drums 3 and 4 to the shaft 7, enabling the two curtain bodies to be lifted up/down by the single shaft 7.
