A rotary atomizing head type coating machine comprising: an air motor that uses compressed air as a power source; a hollow rotational shaft that is rotatably supported by said air motor and an axial tip end of which projects forward from said air motor; a feed tube that extends to the tip end of said rotational shaft through the inside of said rotational shaft to supply paint; a rotary atomizing head that is mounted to the tip end of said rotational shaft and includes an outer peripheral surface enlarged in a cup shape, an inner peripheral surface spreading paint supplied from said feed tube and a paint releasing edge positioned in the tip end to release the paint; and a shaping air ring that surrounds an outer periphery of said rotary atomizing head and an axial tip end of which is arranged in back of said paint releasing edge of said rotary atomizing head, said shaping air ring including: a plurality of first shaping air spurting holes that spurt first shaping air toward the periphery of said paint releasing edge; and a plurality of second shaping air spurting holes that are positioned to be closer to the radial inside than each of said first shaping air spurting holes and are arranged to surround said rotary atomizing head to spurt second shaping air along said outer peripheral surface of said rotary atomizing head, wherein the number of said second shaping air spurting holes is set to be smaller than the number of said first shaping air spurting holes, characterized in that: an inner diameter dimension in the open end of said first shaping air spurting holes is set to be larger than an inner diameter dimension in the open end of said second shaping air spurting holes; and an incident angle (β) of the second shaping air to be spurted from said second shaping air spurting hole to said outer peripheral surface of said rotary atomizing head is set to 12.0 degrees ≤ β ≤ 13.4 degrees. an air motor that uses compressed air as a power source; a hollow rotational shaft that is rotatably supported by said air motor and an axial tip end of which projects forward from said air motor; a feed tube that extends to the tip end of said rotational shaft through the inside of said rotational shaft to supply paint; a rotary atomizing head that is mounted to the tip end of said rotational shaft and includes an outer peripheral surface enlarged in a cup shape, an inner peripheral surface spreading paint supplied from said feed tube and a paint releasing edge positioned in the tip end to release the paint; and a shaping air ring that surrounds an outer periphery of said rotary atomizing head and an axial tip end of which is arranged in back of said paint releasing edge of said rotary atomizing head, said shaping air ring including: a plurality of first shaping air spurting holes that spurt first shaping air toward the periphery of said paint releasing edge; and a plurality of second shaping air spurting holes that are positioned to be closer to the radial inside than each of said first shaping air spurting holes and are arranged to surround said rotary atomizing head to spurt second shaping air along said outer peripheral surface of said rotary atomizing head, wherein the number of said second shaping air spurting holes is set to be smaller than the number of said first shaping air spurting holes, a plurality of first shaping air spurting holes that spurt first shaping air toward the periphery of said paint releasing edge; and a plurality of second shaping air spurting holes that are positioned to be closer to the radial inside than each of said first shaping air spurting holes and are arranged to surround said rotary atomizing head to spurt second shaping air along said outer peripheral surface of said rotary atomizing head, wherein the number of said second shaping air spurting holes is set to be smaller than the number of said first shaping air spurting holes, an inner diameter dimension in the open end of said first shaping air spurting holes is set to be larger than an inner diameter dimension in the open end of said second shaping air spurting holes; and an incident angle (β) of the second shaping air to be spurted from said second shaping air spurting hole to said outer peripheral surface of said rotary atomizing head is set to 12.0 degrees ≤ β ≤ 13.4 degrees.
