Abstract: A rotary atomizing head (4) is mounted on a fore end side of a motor (3). A shaping air ring (9) having a plurality of air outlet holes (10) at fixed intervals is provided on a rear side of the rotary atomizing head (4). Outer surfaces of the air motor (3) and outer surfaces of the shaping air ring (9) are enshrouded over the entire circumference by a cover member (7) formed of an electrically insulating material. An external electrode assembly (13) is provided radially outwardly of the cover member (7). An annular projecting portion (16) which projects forward is provided on the shaping air ring (9) over the entire circumference. The air outlet holes (10) are open in a fore distal end of this annular projecting portion (16). As a result, a corona discharge can be generated by allowing an electric field to be concentrated at the fore distal end of the annular protecting portion (16).

Abstract: A shield member (14) is provided on an outer peripheral side of a front surface section (9D) of a shaping air spurting member (9) and is formed of an annular body radially extending to shield electric flux lines traveling toward rotary atomizing head (4) from each of electrodes (6C) in an external electrode member (6). A tubular insulating member (15) formed of an insulating material covering an outer peripheral surface (9B) of the shaping air spurting member (9) is provided on an outer peripheral side of the shaping air spurting member (9). Further, a discharge buffering member (16) formed of an annular self-returning insulator or semi-conductive material is provided in a position where the shield member (14) is separated from the insulating member (15) between the shield member (14) and the insulating member (15).

Abstract: A shaping air spurting member (9) is formed in a tubular shape by using a conductive material, and is arranged on an outer peripheral side of a rotary atomizing head (4) in a state where a front end thereof is positioned in an intermediate section of the rotary atomizing head (4) in a length direction. The shaping air spurting member (9) has a front surface section (9D) that is provided with many numbers of air spurting holes (10, 12) for spurting shaping air toward paint particles sprayed from the rotary atomizing head (4). In addition, a shield member (14) composed of an annular body extending radially is provided on an outer diameter side of the front surface section (9D) in the shaping air spurting member (9) to shield electric flux lines traveling toward the rotary atomizing head (4) from each of electrodes (6C) in an external electrode member (6).

Abstract: A rotation restricting mechanism is provided between a mounting shaft section of a rotational shaft and a mounting tube section of a rotary atomizing head. The rotation restricting mechanism is constituted by a male spline member which is provided on the outer peripheral side of the mounting shaft section, and a female spline member which is provided on the inner peripheral side of the mounting tube section. By meshing engagement of the male spline member with the female spline member, the rotation restricting mechanism restricts rotational displacements of the rotary atomizing head relative to the rotational shaft (14).
