PURPOSE: An expansion type winder of air filter with improved winding efficiency is provided, which can conduct smoothly winding/separation operation in the course of changing air filter by winding as circumference type, thus improving winding efficiency. The filter shortens the operation time by adopting a simple method to hang the front end of air filter to hook pin of bobbin unit and enlarge the scope of extension and contraction of winder after separating winder from main body by operating removable handle, thus enabling easy separation of roll filter and winder. CONSTITUTION: The system comprises a bobbin bar(40), a tail spindle part(60), and a driving part(50). The extension and contraction of air filter are conducted by the bobbin bar(40). At the tail spindle part(60), by operation of tail handle(61), two-way latch proceed alternately to conduct extension and contraction of the bobbin bar(40). At the driving part(50), by operation of driving handle(51), driving force is transmitted to the bobbin bar(40). The bobbin bar(40) contains pentagonal bobbin plate(41), many connecting rods which penetrate the bobbin plate(41) and hook pin.
