PROBLEM TO BE SOLVED: To provide a rolling screen capable of preventing a weight member from moving up and down while making the weight member large-sized in adjusting a daylighting quantity by relative movements of front and rear double screens and further in switching of an elevating operation.SOLUTION: A rolling screen according to the present invention is configured to suspend front and rear double screens 5a, 5b, and comprises two take-up shafts 4a, 4b, and an operation device 10 which allows the two take-up shafts 4a, 4b to rotate. The operation device 10 comprises a rotation transmission mechanism which is operable in lighting control according to how the front and rear double screens 5a, 5b overlap with each other such that a rotation quantity by which the first screen 5a is unwound by the take-up shaft 4a is substantially equal to a rotation quantity by which the second screen 5b is wound from the take-up shaft 4b, and a rotation quantity by which the first screen 5a wound by the take-up shaft 4a is substantially equal to a rotation quantity by which the second screen 5b is unwound from the take-up shaft 4b.SELECTED DRAWING: Figure 1
【課題】前後二重のスクリーンの相対移動による採光量の調整時、更には昇降操作の切り替え時に、錘部材の大型化を抑えつつ錘部材が上下動することを防止可能としたロールスクリーンを提供する。【解決手段】本発明のロールスクリーンは、前後二重のスクリーン５ａ，５ｂを吊下するロールスクリーンであって、２本の巻取軸４ａ，４ｂと、この２本の巻取軸４ａ，４ｂの回転を操作可能とする操作装置１０とを備える。操作装置１０は、当該前後二重のスクリーン５ａ，５ｂの重なり具合により調光操作する際に、巻取軸４ｂから第２スクリーン５ｂを巻き取る回転量に対して、巻取軸４ａにて第１スクリーン５ａを巻き戻す回転量をほぼ等しく操作可能とし、且つ巻取軸４ｂから第２スクリーン５ｂを巻き戻す回転量に対して、巻取軸４ａにて第１スクリーン５ａを巻き取る回転量をほぼ等しく操作可能な回転伝達機構を備える。【選択図】図１
