Abstract
A rotary atomizing-head type coating machine, wherein a paint passage for flowing a paint to a rotary atomizing-head, a turbine air passage flowing a turbine air to the turbine of an air motor, a discharge air passage for flowing the turbine air after driving the turbine to the outside in the form of a discharge air, and a heat insulating air discharge passage of a heat insulated air passage axially extending while surrounding the discharge air passage and allowing hot heat insulated air to flow therein are formed in the bottom part of a housing body forming a housing. Thus, even if the turbine air expanded in a heat insulated state and reduced in temperature flows in the discharge air passage, the housing 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.
