Abstract
An annular gap space (), into which a part of turbine air for driving a turbine () and exhaust air discharged from a rear thrust air bearing () flow out, is provided between an inner peripheral surface (B) of a rotational shaft () and an outer peripheral surface (B) of a feed tube (). Air outflow holes () are provided in the rotational shaft () to be positioned between a radial air bearing () and a rotary atomizing head () and to be radially bored through the rotational shaft (). As a result, the exhaust air flowing in the annular gap space () flows out outside of the rotational shaft () from the air outflow holes () in a position behind the rotary atomizing head ().
