PROBLEM TO BE SOLVED: To wash a rotary atomization head without using a dedicated washing means with regard to a coating apparatus fitted with a coating gun having the rotary atomization head. SOLUTION: In the coating apparatus, an ejection opening 12 opens toward the peripheral edge 11a of the rotary atomization head 11, and a washing liquid supply means B for supplying the washing liquid is connected to a supply passage 21 for shaping air in the coating gun A. After coating, the washing liquid is supplied to the supply passage 21 in a body 10. When the washing liquid is sprayed from the ejection opening 12 to the peripheral edge 11a of the rotary atomization head 11, a coating adherent to the peripheral edge 11a is removed. Since the washing liquid is supplied and ejected by using the supply passage 21 and the ejection opening 12, a dedicated washing apparatus is unnecessary. COPYRIGHT: (C)2005,JPO&NCIPI
