Beschreibung
Zusammenfassung:	A screen device (1) provided with: cylindrical body (2A) having a prescribed inner diameter and comprising a plurality of wire rods (3A); four restriction parts for restricting movement of one end and the other end of the respective wire rods (3A) to the radial outside and inside of the cylindrical body (2A), respectively; an annular sliding part (4A) provided at one end of the cylindrical body (2A); a control device for rotating the annular sliding part (4A) around a central axis (O). The inside of the annular sliding part (4A) has a shape in which protruding parts (43a) protruding toward the central axis (O) and recessed parts (44a) recessed away from the central axis (O) continue alternately and regularly. The control device is configured such that the size of an opening formed between two adjacent wire rods (3A) on one end side of the cylindrical body (2A) can be made larger than that of an opening formed between two adjacent wire rods (3A) on the other end side, by rotating the annular sliding part (4A)
