OPENING/CLOSING DEVICE

To provide a technique capable of transmitting electric power to a functional part at least when a shielding part is in a closed state.SOLUTION: A rolling screen 1 is provided with a screen 14 and a weight bar 15 that are movably provided by a take-up pipe 13 to open and close the space. The screen 14 and the weight bar 15 include a power reception unit 162 that can receive electric power in a non-contact manner, and a detection unit 164 that functions by the electric power received by the power reception unit 162. When the power reception unit 162 is located in a power transmissive area of a power transmission unit 161 that is provided in the vicinity of a movable path where the screen 14 and the weight bar 15 can move and can transmit electric power in a non-contact manner, in a state in which the screen 14 and the weight bar 15 are closed, the power reception unit 162 receives electric power from the power transmission unit 161 to cause the detection unit 164 to function.SELECTED DRAWING: Figure 1 【課題】少なくとも遮蔽部が閉状態にある場合に、機能部に対して送電することができる技術を提供する。【解決手段】巻取パイプ１３により可動に設けられ空間を開閉するスクリーン１４及びウエイトバー１５を備えたロールスクリーン１であって、スクリーン１４及びウエイトバー１５は、非接触で電力を受電することができる受電部１６２と、該受電部１６２で受電された電力によって機能する検知部１６４とを備え、前記スクリーン１４及びウエイトバー１５が可動する可動経路近傍に設けられて非接触で電力を送電することができる送電部１６１の送電可能領域に、スクリーン１４及びウエイトバー１５が閉状態において受電部１６２が位置する場合に、受電部１６２は送電部１６１から受電して検知部１６４を機能させる。【選択図】図１
