Claims

[Scope of utility model registration request]

In an axial cooling blower in which a propeller fan is driven by an electric motor in which a rotor rotates inside an armature fixed to a stator frame, a sleeve-shaped oil-impregnated bearing metal is fixed to the shaft center of the rotor, and the oil-impregnated bearing metal is fixed to the shaft center of the rotor. A cooling blower characterized in that the bearing metal is rotatably fitted and supported by a shaft having one end fixed to the stator frame.
