WINDING SHADE DEVICE

A winding shade device includes a sheet-form member, a winding shaft for winding the sheet-form member, and a support member that is secured to a hinge door and that rotatably supports the winding shaft. The support member has a plurality of elastically deforming parts that push on and rotatably support the outer periphery of the winding shaft, which is passed through a through-hole. The plurality of elastically deforming parts have a plurality of first elastically deforming parts which are arranged along a closing direction with respect to the hinge door from the center of the winding shaft, and which are arranged in line symmetry with respect to a line passing through the center of the through-hole and extending in the opening and closing direction of the hinge door.
