PROBLEM TO BE SOLVED: To restrain heat generation by using an axial air-gap type micro fan motor capable of oscillating by an eccentric rotor with the fan, and expedite cooling of a heat generation member by forming an effective mounting structure for a moving body machine. SOLUTION: This eccentric rotor with the fan has a bearing portion provided in the center of rotation, a commutator 1b provided on one side of a printed wiring board 1, air-cored armature coils 2, 22 which are disposed outward in a radial direction of the bearing portion on the other side of the printed wiring board and receive power from the commutator, and a tungsten eccentric weight 33. A wing-shaped impeller 55e facing rearward is provided at least on a portion of an outer circumference, and the tungsten eccentric weight is also composed at an impeller 33d with a turning outer diameter roughly matching with an outer circumference, thus forming suspended portions in the respective impellers in the axial directions.
