Claims5
A rotary atomizing coating device comprising a rotary atomizing head coupled to a rotary shaft of a rotary drive source and configured to discharge a paint by a centrifugal force caused by rotation thereof, the rotary atomizing coating device coating a workpiece with the discharged paint, wherein
- the rotary atomizing head includes:
- a first bell cup including a first paint discharge surface configured to thin the paint by the centrifugal force;
- a second bell cup fitted to an outer side of the first bell cup and including a second paint discharge surface configured to thin the paint;
- a paint supply passage which extends in an axial direction of the rotary shaft and through which the paint is supplied;
- and
- an inner member disposed inside the first bell cup and communicating with the paint supply passage, and wherein
- an outer peripheral surface of the inner member includes a paint discharge hole communicating with the paint supply passage, and the first bell cup is formed with, at a position near the paint discharge hole, a through hole communicating with the second bell cup, and
- the paint discharge hole faces the first paint discharge surface and the through hole in a radial direction of the first bell cup.
