PURPOSE: A fan motor is provided to reduce the generation of noise by supporting a rotational shaft with an oilless metal bearing. CONSTITUTION: A rotor(53) is provided with a rotational shaft(52) on one side thereof. The rotor(53) is inserted into a rotor rotational hole(H) of a stator(50). A fixing housing(3) is provided with a shaft through bore(1) through which the rotational shaft(52) penetrates. Both ends of the fixing housing(3) are fixed on the stator(50) with a bolt(2). A bearing is provided between the fixing housing(3) and the rotational shaft(52). The bearing maintains a uniform rotation of the rotational shaft(52) in case that a side of the rotational shaft(52) is supported. A fixer is installed between the rotational shaft(52) and the fixing housing(3) to prevent the rotational shaft(52) from falling out.
