Abstract

PURPOSE:To perform a titled treatment uniformly by bringing a treating agent holding body which has a surface of the shape conforming to the shape of the surface of a material to be treated into contact with the material to be treated and turning the holding body or the material to be treated. CONSTITUTION:A material 2 to be treated, for example, an Al alloy wheel is fixed on a stage 3, and an advancing and retreating means 24 of a supply means 23 for a treating agent is operated to extend a piston rod 25, thereby moving a cover 27 to the position right under a treating agent holding body 10. The body 10 is moved downward by a vertical movable means 14 until the body 10 is moved downward by a vertical movable means 14 until the body 10 is concealed fully with a cover 27. The surface treating agent is then sprayed through a spray part 26 by a means 23 onto the surface 12 of the body 10 so that the surface treating agent is impregnated and held thereon. The body 10 is moved upward and is removed from the cover 27, then the cover 27 is retreated. The body 10 is moved downward by a means 14 to bring the surface 12 thereof into contact with the surface 11 of the wheel, and electric motors 16, 19 are operated to rotate the plate 3 and a fixing plate 16 whereby the treating agent is coated uniformly on the surface 11 of the wheel.
