<P>PROBLEM TO BE SOLVED: To provide a pleat screen that is reducible in cost while an opening/closing cord for adjusting the length of a screen material and an insertion hole through which the cord is run do not spoil the beauty and light does not leak out through the insertion hole either. <P>SOLUTION: As reverse-side folds 4 forming mountains of a screen material 2 on an outdoor side, projection folds 41 which have ridges at relatively projecting positions as compared with other folds and a non-projection fold 42 which has a ridge at a relatively non-projecting position are formed, and those projection folds 41 and non-projection fold 42 are mixedly distributed. Parts of the screen material 2 which form areas of predetermined width on both sides of a ridge of a projection fold 41 are joined together one over the other to form a projection piece 14 which projects to the reverse side along the projection fold 41, and an insertion hole 9 through which an opening/closing cord 8 is run is formed in the projection piece 14. <P>COPYRIGHT: (C)2013,JPO&INPIT |
