A screen device including a parallel motion mechanism using wires inserted into a screen, an upper part of the screen being restricted from bending by external forces such as wind. One end of a screen made expandable and contractible by alternate folding in opposite directions is connected to a longitudinal frame member of a screen frame, and another end is connected to a movable frame to make the screen openable and closable by lateral pulling. A parallel motion mechanism moving parallel the movable frame by flexible linkage members including wires is inserted in an expansion and contraction direction of the screen. A part of the wires are tensioned along a portion above the screen as wires for hanging the screen and are inserted into an inner hole of a ring portion of a hanging member, the upper end of the screen being sandwiched by a sandwiching portion of the hanging member.
