Abstract
A rotary atomization type painting device includes an atomization head that supplies paint from a paint supply machine. The atomization head has an outer member that includes a truncated conical body, and an inner member that is disposed inside the outer member. The inner member has an annular protruding part that protrudes toward a large diameter side opening. The paint is lead out from a plurality of lead-out holes of the inner member to a root of the annular protruding part. At a root position in an axial direction, an angle in a lead-out direction of each of the lead-out holes with respect to an axis, and an angle of an inner surface of the annular protruding part with respect to the axis are made equal.
