Shade device

A shade device comprising:

• a pair of guide rails that extend in parallel to each other in a first direction as one direction;
• a winding shaft that extends in a second direction as a direction orthogonal to the first direction on one end side of both of the guide rails in the first direction;
• a light-shielding sheet that has one end portion coupled to the winding shaft;
• a rod that extends in the second direction and is coupled to the other end portion of the light-shielding sheet;
• a pair of sliding members that are attached to both of the end portions of the rod in a longitudinal direction and are slidably supported by both of the guide rails;
• and
• a pair of guide members that are attached to both of the end portions of the rod in the longitudinal direction, are slidably supported by both of the guide rails, and are fixed in a state where both of the side edges of the light-shielding sheet are folded, wherein
• the shade device is configured such that, when the rod moves in the first direction approaching the winding shaft, the light-shielding sheet is brought into a storage state in which the light-shielding sheet is wound around the winding shaft while both of the side edges folded at the guide rails are unfolded, and a light-transmitting portion disposed in a vehicle allows light to pass therethrough, and
• a fixing position of the side edge at the guide member is more separated from the winding shaft than from the rod, and a range in which folding and unfolding of the side edge in the storage state of the light-shielding sheet changes overlaps with a range of the rod in the first direction.
