<p>A rotation restricting mechanism (25) is provided between a mounting shaft section (15) of a rotational shaft (14) and a mounting tube section (24) of a rotary atomizing head (21). The rotation restricting mechanism (25) is constituted by a male spline member (26) which is provided on the outer peripheral side of the mounting shaft section (15), and a female spline member (27) which is provided on the inner peripheral side of the mounting tube section (24). By meshing engagement of the male spline member (26) with the female spline member (27), the rotation restricting mechanism (25) restricts rotational displacements of the rotary atomizing head (21) relative to the rotational shaft (14).</p> |
