<p>Included are: a windup device; a screen attached to the windup device so as to be drawn therefrom and housed therein; a stay attached to a drawing-side edge of the screen and including a main body and a pair of connecting end portions; and a pair of arms each including a distal end portion connected to the connecting end portion so as to rotate relative thereto and a proximal end portion supported by the windup device so as to rotate relative thereto, the pair of arms being configured to change a position between a folded position and an extended position through the rotary movement. The pair of arms each include: a pivot base including a one-end-side portion extending toward a vertical frame side in the extended position and the other-end-side portion extending along the vertical frame in a manner of being bent from a distal end portion of the one-end-side portion; and an arm portion connected the other-end-side portion and extending along the vertical frame in the extended position, and the pair of connecting end portions are each configured so as to extend and retract in a state of being biased in an extending direction along a drawing/housing direction of the screen.</p> |
