PURPOSE:To prevent paint from adhering to a shaft during the process by composing of a holder having a receiving hole, to which one of a rotor shaft is inserted, and a piston having a holding hole opposed to the receiving hole for varying the interval of both holes, and externally applying high pressure in the state that the shaft is held in both holes. CONSTITUTION:A holder 3 having a receiving hole 3b, to which one of shafts 2a, 2b projected from both sides of a rotor 2 is inserted, and a cylinder 4 provided therein with a piston 6 having a holding hole 6b for varying the interval to the hole 3b are provided. Air is fed from an air source in the state that the shafts 2a, 2b are held in the holes 3b, 6b, and both holes are increased in pressure higher than the exterior. In this manner, it can completely prevent the powder paint from being adhered to the shaft portion, thereby omitting the cleaning step of the shaft. |
