Abstract
A roll shade device includes: a fixed shaft fixed to a roof of a vehicle and extending in a vehicle width direction; a flexible rotation shaft into which the fixed shaft is inserted; a light shielding sheet whose first terminal end portion is fixed to the rotation shaft, and which is in an unfolded state where light passing through a light transmitting portion provided to the roof is blocked or is in a winding state where light is allowed to pass; and a torsion spring which is accommodated between the fixed shaft and the rotation shaft, and which biases the rotation shaft in a rotation direction in which the light shielding sheet is wound so that twist of the rotation shaft becomes symmetrical in the vehicle width direction.
