On a rotary atomizer head (7), an outer circumferential surface cleaning passage (14) opening onto the outer circumferential surface (13) of the atomizer head is provided to cause cleaning fluid supplied from a feed tube (6) to flow out to a circular gap (20) between the rotary atomizer head (7) and a shaping air ring (15). The outflow opening (14C1) of the outflow passage (14C) configuring said outer circumferential surface cleaning passage (14) is provided at a position that is set back by a distance (L1) into the circular gap (20) from the front end face (17A) of a front ring region (17) configuring the shaping air ring (15). Additionally, the outflow opening (14C1) opens into the circular gap (20) at an angle (α1) that forms an acute angle with respect to the outer circumferential surface (13) of the atomizer head. |
