PURPOSE: A washing device is provided to minimize change of vibrational property due to a motor. CONSTITUTION: A first and second cooling hole(218a,218b) are symmetrically matched based on a central line. In order to enable a inside of a rotor to be sloped, a first blade(217a) is installed in a base. The first blade generates an airflow component to an internal circumference direction and an internal vertical direction through the first cooling hole. The second blade(217b) generates the airflow component to the internal circumference direction fo the rotor and an external vertical direction of the rotor through the second cooling hole. |
