PURPOSE: An air blow apparatus of a spindle is provided to increase the efficiency of foreign material removal by compensating the pressure loss as a high pressure. CONSTITUTION: An air blow apparatus of a spindle comprises a draw bar(100), a collet pipe(130), a contracting ring(140), a pressing ring(150), and an adjusting bolt(160). The draw bar has a sill(110) and a female screw(120). The female screw is formed in the outer diameter part of the sill. The collet pipe has a plurality of cut pieces. If the outer diameter of the collet pipe is pressurized, the collet pipe is contracted to the inside diameter. An inside diameter of the pressing ring is tapered, and is inserted into an outer diameter part of the contracting ring.
