Abstract: When a light-shielding sheet enters guide rails, engagement belts of the light-shielding sheet engage with the guide rails. A roll-screen device includes a winding roller, a light-shielding sheet, guide rails, and guide sections. The light-shielding sheet includes a sheet body, and engagement belts provided along side edges at both sides of the sheet body in a vehicle width direction. The sheet body and the engagement belts are rolled up on the winding roller such that the sheet body and the engagement belts overlap each other. Each guide rail includes engagement wall section which is located at a vehicle widthwise inner side of the engagement belt and engages with the engagement belt to prevent the light-shielding sheet from falling out of the guide rail. The guide section includes a guide piece configured to put a distance between the engagement belt and the sheet body before the light-shielding sheet enters the guide rail.

Abstract: A roller shade includes a light shielding sheet which can be rolled up in a roll shape, a roller and an electric motor for openably moving the light shielding sheet, guide belts connected to respective lower surfaces of side end parts of the light shielding sheet in a sheet width direction, and a pair of guide parts each having a guide space which receives a corresponding one of the side end parts of the light shielding sheet in the sheet width direction and a corresponding one of the guide belts, for guiding the side end part and the guide belt. In the roller shade, the light shielding sheet is prevented from being creased when the light shielding sheet moves in the width direction while being rolled or unrolled, due to lack of a tension of the light shielding sheet in the width direction.
