To provide a roll shade device that is able to hinder wrinkling of a shading sheet in an unrolled state and is able to prevent an increase in the outer diameter of the shading sheet in a rolled state.SOLUTION: A roll shade device comprises: a fixed shaft 31 extending in a vehicle width direction; a flexible rotary shaft 23 with the fixed shaft 31 inserted therein; a shading sheet 24 whose first terminal part is fixed to the rotary shaft 23 and which is brought into an unrolled state for blocking light passing through a translucent part, provided in a roof, as a second terminal part is moved or into a rolled state allowing passage of the light; and first and second torsion springs 33, 34 whose first leg parts 35 are locked to the middle, in the vehicle width direction, of the fixed shaft 31 and whose second leg parts 36 are locked to a spring holding hook 32 fixed to the leading end part, in the vehicle width direction, of the rotary shaft 23, and that urge the rotary shaft 23 in a rotating direction in which the shading sheet 24 is rolled such that torsion of the rotary shaft 23 is symmetrical in the vehicle width direction.SELECTED DRAWING: Figure 3

    【課題】展開状態にある遮光シートに生じる皺を抑制でき、且つ、巻取状態にある遮光シートの外径が大きくなることを抑制できるロールシェード装置を提供する。【解決手段】車両の幅方向に延在する固定シャフト31と、固定シャフト31が挿通された可撓性の回転シャフト23と、第1端末部が回転シャフト23に固定され第2端末部の移動に伴ってルーフに設けられた透光部を通過する光を遮断する展開状態となり、あるいはその光の通過を許容する巻取状態となる遮光シート24と、第1脚部35が固定シャフト31の車両の幅方向における中央に掛止されるとともに第2脚部36が回転シャフト23の車両の幅方向における先端部に固定されたばね保持駒32に掛止され、回転シャフト23の捩れが車両の幅方向において対称になるように遮光シート24を巻き取る回転方向に回転シャフト23を付勢する第1及び第2捩りばね33,34とを備える。【選択図】図3
