See full text

The present invention relates to a clothes dryer, in which mounting/dismounting of a fan is made easy by clamping a motor shaft with a tool, such as a spanner, effectively in cases when the fan is dismounted/mounted from/on the motor shaft for service of the product. For this, a motor shaft structure, in a clothes dryer including a drying drum rotatably mounted in a body, a motor bracket fixed to a bottom of an inside of the body, a motor mounted on the motor bracket for generating a rotating power, and a fan coupled to the motor with a shaft, includes chambered parts.
