<p>A rotary atomizing-head type coating machine, wherein a paint passage (11) for flowing a paint to a rotary atomizing-head (8), a turbine air passage (14) flowing a turbine air to the turbine (7C) of an air motor (7), a discharge air passage (18) for flowing the turbine air after driving the turbine (7C) to the outside in the form of a discharge air, and a heat insulated air discharge passage (19C) of a heat insulated air passage (19) axially extending while surrounding the discharge air passage (18) and allowing hot heat insulated air to flow therein are formed in the bottom part (4B) of a housing body (4) forming a housing (3). Thus, even if the turbine air expanded in a heat insulated state and reduced in temperature flows in the discharge air passage (18), the housing (3) can be prevented from being cooled by the discharge air by flowing a heat insulated air with a temperature higher than that of the discharge air in the heat insulated air discharge passage (19C).</p> |
