Abstract
In a watertight brushless fan motor of the present invention, a first pad is disposed in a first space between a stator and a circuit substrate , A second pad is disposed in a second space between the circuit substrate and a plate-like section of a case . Spaces between the plate-like section of the case and a bearing supporting cylindrical section are formed with an insulating resin in such a manner that the stator and the circuit substrate are included inside, thereby forming a molded part , With this arrangement, the watertight brushless fan motor is provided that can prevent occurrence of a crack in the outer surface of the molded part due to the so-called molding shrinkage of the insulating resin or expansion and shrinkage of the insulating resin caused by a change in ambient temperature.
