ABSTRACT:
A relative movement of a fan1toward a motor2,which is one of the relative movements of the fan1with respect to a rotating shaft23,is restricted by an inner ring221of a radial bearing22.Due to this, the relative movement of the fan1toward the motor2is restricted by the inner ring221when the joining force between the fan1and the rotary shaft23is decreased, so that the contact between the fan1and the housing21can be prevented. Moreover, as the inner ring221rotates together with the rotating shaft23,a rotational force is transferred from the inner ring221to the fan1in a state in which the relative movement of the fan1toward the motor2is restricted by the inner ring221.
