<P>PROBLEM TO BE SOLVED: To solve the problem that, a rigid band body is distorted by the weight of a pleated screen to damage horizontality at an upper end edge of the pleated screen, pleats are protruded, expanded or disordered by rigidity or plastic deformation of the pleated screen in approach of a post to increase air pressure between posts disposed oppositely especially when reducing the distance between the posts, so that considerable protrusion or disorder may occur and the pleated screen may become extremely bad in appearance. <P>SOLUTION: In a screen device, between an inner right slope of one of pleated screens which are disposed while being opposed to each other and integrally formed in a pleated shape with an arbitrary length, and an inner left slope of the other pleated screen, an upper screen setter disposed in an upper part and a lower screen setter disposed in a lower part are installed while being divided vertically, and the pleated screens are spread over a first post and a second post which are opposed to each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
