PROBLEM TO BE SOLVED: To solve problems in a low-priced folding fan, such as little wind quantity due to weak bracing of folding fan ribs in usage from the beginning, unstable wind quantity due to a changeable opening/closing angle of the folding fan, or early hand tiring when holding power is strengthened to hold a folding fan opening maintaining state onto a central axle for preventing the above.SOLUTION: In a folding fan ribs opening/closing regulator, plan view U shape base frames with an opening around a projecting end of the central axle are right and left disposed onto the central axle projecting ends mounted to sandwich folding fan ribs between right and left main rib base ends. The base frame has front and rear walls to cover front and rear of the main rib and a boss seat with engaging furrows engraved roughly in equally disposed shape around the opening. Moreover, a right and left connecting frame is disposed to sandwich and hold lower side detouringly the boss seats engaging the engaging furrows on right and left boss seats outer sides. |
