PURPOSE: A structure for fixing a blade of indoor unit of air conditioner is provided to reduce noise and to improve abrasion resistance. CONSTITUTION: A fixing plate(21) has a joining hole(24) facing joining protrusions(23) protrusively formed on both sides of a blade(22) installed to control air direction of an air conditioner. The joining hole is formed to be square to reduce frictional noise by minimizing contacting area. The wind direction control unit and the fixing plate are made of ABS(Acrylonitrile Butadiene Styrene) to improve abrasion resistance against abrasion due to the minimized contacting area.
