ABSTRACT:
An axial flow fan motor is provided with a motor housing that supports a bearing box. Bearings supported by the bearing box rotatably support a rotary shaft on which a yoke and an impeller are fixed. A U-letter shaped groove is provided on one portion of the motor housing, which is adapted to be engaged with a projection provided on an outer circumference on a PC board assembled with a control circuit. Since the PC board is securely positioned, the tip end of a probe of an automatic test machine can securely contact the terminal pin.
