Abstract:
The present invention comprises: an air motor (3); a rotation shaft (4) that is rotatably supported by the air motor (3); a feed tube (5) that extends through the inside of the rotation shaft (4) to the distal end thereof; a rotary atomizing head (6) that is attached to the distal end of the rotation shaft (4); and a shaping air ring (7) that surrounds the outer periphery of the rotary atomizing head (6), the distal end in the axial direction of the shaping air ring being disposed more toward the rear than a discharge end edge (6D) of the rotary atomizing head (6). The shaping air ring (7) is provided with a plurality of first shaping air-jetting holes (9) and a plurality of second shaping air-jetting holes (10). An inner diameter dimension (d1) of the first shaping air-jetting holes (9) is set to be larger than an inner diameter dimension (d2) of the second shaping air-jetting holes (10). The number (N2) of the second shaping air-jetting holes (10) is set to be less than the number of (N1) of the first shaping air-jetting holes (9).
