ABSTRACT:
In an electrostatic powder coating method of the present invention, a wheel is placed on a supporting jig and powder is electrostatically applied on the surface of the wheel. Unnecessary powder adhered on a tapered surface of a bolt hole is eliminated by suctioning the air inside the bolt hole through a suction opening of the supporting jig. Thereby, a coating film can be formed on the road wheel without applying a coating on the tapered surface of the bolt hole.
