Abstract
A window shade device including a shade, a pair of rails disposed so as to have a gradually decreasing spacing therebetween from proximal ends to distal ends thereof, a housing device disposed on the proximal end side, a drawing member supporting a drawing-side edge of the shade, and a pair of runners connected to both ends of the drawing member and configured to respectively move along the pair of rails. Upon the pair of runners being guided by the pair of rails to move, the drawing member deforms to have a dimension varying in the width direction of the shade, and causes the drawing-side edge of the shade to advance and retract in the drawing/housing direction such that the drawing-side edge is disposed on the drawing side exceeding the pair of runners in a state in which the shade is drawn.
