<P>PROBLEM TO BE SOLVED: To cut manufacturing cost and facilitate assembly by getting rid of pins and equalizing the shapes of all blades. Ž<P>SOLUTION: The knock-down folding fan is made by combining a plurality of round fan-shaped blades 2 and can be separated into the blades. Each of the blades 2 is made of a decorative plate 4 and a center rib 3. The center rib 3 has a slender intermediate portion 32 and a lower end pivotal portion 33. The pivotal portion 33 has an engagement portion rotatably engaging with the pivotal portions of different blades on the front side and the rear side. Engagement/separation in the engagement portions permits engagement/separation even without using a pin. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
