A first wash fluid discharging passage (15) having an outlet end thereof opened to an outer peripheral surface (8C) is provided on a rotary atomizing head (7) and positioned behind a paint reservoir (12). On the other hand, a second wash fluid discharging passage (20) having an outlet end thereof opened to the paint reservoir (12) is also provided on the rotary atomizing head (7) positioned around a fore end of a paint tube (18). In addition, a nozzle (22) is provided at a fore outlet end of a wash fluid tube (19). The nozzle (22) internally defines an annular chamber (24) for pooling a wash fluid. The nozzle (22) is provided with first and second outlet openings (25, 26) to spurt a wash fluid toward the first and second wash fluid discharging passages (15, 20). Further, a check valve (27) is provided in the annular chamber (24) of the nozzle (22) to prevent a reverse flow of a wash fluid. |
