PURPOSE: A supporting structure of a fan motor is provided to improve the stability and the durability of a fan and to improve operation efficiency because a belt is driven without damages by preventing a driving shaft of a motor being tilted. CONSTITUTION: A supporting structure of a fan motor comprises a body(10), an installation frame(12), and a bracket(40). The body is formed into an edge shape in which a through-hole(11) is formed. A blade(2) is formed in the central part of the through-hole. A motor is accommodated in one edge of the body. The installation frame is installed across the through-hole of the body and a rotary shaft(21) of the blade is joined to the central part of the installation frame to be rotated. The bracket is composed of a motor installing plate and an expansion supporting unit. A through-hole where a driving shaft of the motor is penetrated is formed in the central part of the motor installing plate. The expansion supporting unit is projected to a direction orthogonal to the driving shaft of the motor in the outer end part of the motor installing plate, thereby being fixed and installed in the installation plate.
