<P>PROBLEM TO BE SOLVED: To provide a light-weight louver device which is friendly for users and objects, of which the assemblability is improved and further of which the strength is high even if it is thin. <P>SOLUTION: A first bending part 3d is formed by folding one terminal side 3c in a width direction of a blade body 3a comprised of a rectangular metal plate at an obtuse angle and into U shape, and a second folding part 3f is formed by folding another terminal side 3e at ab obtuse angle. A junction 3b which is welded while being overlapped with a strut 1 at both terminal sides in a length direction of the blade body 3a, is folded and formed, respectively, between the first folding part 3d and the second folding part 3f. <P>COPYRIGHT: (C)2013,JPO&INPIT |
