PROBLEM TO BE SOLVED: To enable a change in transmittance of visible light of a shade and allow an area having target transmittance to spread without being influenced by a prior spread state.SOLUTION: A shade device 20 comprises: a shade 50 including a first area (for example, a high transmittance area 52) and a second area (for example, a low transmittance area 54) having visible light transmittance different from the first area; a first winding device 30 for winding the shade 50 from an end part on the first area side; a second winding device 40 for winding the shade 50 from an end part on the second area side; moving means 60 for moving the first winding device 30 and the second winding device 40 relatively; and winding drive means 70. When spread from a non-spread state, the shade 50 is in an initial one-side wound state in which the shade is wounded by at least one of the first winding device 30 and the second winding device 40, or an initial one-side wound state in which both of the first area and the second area are wound by the first winding device or the second winding device.SELECTED DRAWING: Figure 1

    【課題】シェードの可視光線の透過率を変更することができ、かつ、前回の展開状態に左右されずに、目的とする透過率の領域を展開させることができるようにすること。【解決手段】シェード装置20は、第1領域(例えば、高透過率領域52)と、第1領域とは異なる可視光線透過率を示す第2領域(例えば、低透過率領域54)とを含むシェード50と、シェード50を第1領域側の端部から巻取る第1巻取装置30と、シェード50を第2領域側の端部から巻取る第2巻取装置40と、第1巻取装置30と第2巻取装置40とを相対的に移動させる移動手段60と、巻取駆動手段70とを備える。非展開状態から展開するとき、シェード50が第1巻取装置30及び第2巻取装置40の少なくとも一方に巻取られた初期片方巻取状態、又は、第1領域および第2領域の両方が、第1巻取装置若しくは第2巻取装置に巻取られた初期片方巻取状態とする。【選択図】図1
