A shaft mounting structure is provided to reduce the costs for service in respect of products by preventing the abrasion of a motor shaft and a coupling member. A shaft mounting structure includes a fan motor, a motor shaft(234), a blower fan(220), a bush(223), a coupling member, and a shaft coupling hole(236). The fan motor generates rotation power by being applied by the external power. The motor shaft is coupled to the center of the fan motor. The motor shaft is rotated by the rotation power of the fan motor. The blower fan is rotated by the rotation of the motor shaft to make the air flow. The bush is placed at the rotation center of the blower fan, and transmits the rotation power of the motor shaft. The coupling member penetrates the motor shaft crossing the length of the motor shaft. The shaft coupling hole is for the coupling member to penetrate the motor shaft for guiding the coupling member to be coupled.
