摘要: A rotary atomizing electrostatic coating apparatus includes air feed passages connected to an air bearing, a turbine, and a shaping air cap, respectively. In any one of air feed passages, a divergence portion for causing a portion of air flowing in the one air feed passage to diverge from the one air feed passage is formed so that a diverging air flows into an interior of the drive shaft. As a result, it is not necessary to provide an additional, air feed passage and an air source therefor for preventing paint from entering a bearing clearance between the drive shaft and the air motor. As a result, a size of the apparatus will not be large and a cost of the apparatus will not substantially increase.
