PROBLEM TO BE SOLVED: To provide a fan guard integrated axial flow fan motor, which is reduced in noise due to the fan guard and also reduced in drop of an air flow rate, in an axial flow fan motor of a type provided with a fan guard. SOLUTION: A fan guard of a fan case surface has a plurality of upper surface blow out openings 5, and is provided with a plurality of side surface blow out openings 2 also in a side surface direction. Since air sucked from an opposite surface of a fan case 1 by the rotor fan is discharged from the side surface blow out opening 2 in addition to the upper surface blow out opening 5, reduction of noise, and sufficient blow out flow rate are secured.
